Advertising is a form of communication that typically attempts to persuade potential customers to purchase or to consume more of a particular brand of product or service. “While now central to the contemporary global economy and the reproduction of global production networks, it is only quite recently that advertising has been more than a marginal influence on patterns of sales and production. The formation of modern advertising was intimately bound up with the emergence of new forms of monopoly capitalism around the end of the 19th and beginning of the 20th century as one element in corporate strategies to create, organize and where possible control markets, especially for mass produced consumer goods. Mass production necessitated mass consumption, and this in turn required a certain homogenization of consumer tastes for final products. At its limit, this involved seeking to create ‘world cultural convergence’, to homogenize consumer tastes and engineer a ‘convergence of lifestyle, culture and behaviors among consumer segments across the world’.” 
Many advertisements are designed to generate increased consumption of those products and services through the creation and reinvention of the “brand image” . For these purposes, advertisements sometimes embed their persuasive message with factual information. Every major medium is used to deliver these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet, carrier bags and billboards. Advertising is often placed by an advertising agency on behalf of a company or other organization.
Organizations that frequently spend large sums of money on advertising that sells what is not, strictly speaking, a product or service include political parties, interest groups, religious organizations, and military recruiters. Non-profit organizations are not typical advertising clients, and may rely on free modes of persuasion, such as public service announcements.
Money spent on advertising has increased dramatically in recent years. In 2007, spending on advertising has been estimated at over $150 billion in the United States and $385 billion worldwide, and the latter to exceed $450 billion by 2010.
While advertising can be seen as necessary for economic growth, it is not without social costs. Unsolicited Commercial Email and other forms of spam have become so prevalent as to have become a major nuisance to users of these services, as well as being a financial burden on internet service providers. Advertising is increasingly invading public spaces, such as schools, which some critics argue is a form of child exploitation.

2) Seo Marketing:
Search Engine Optimization
Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site from search engines via “natural” (“organic” or “algorithmic”) search results. Typically, the earlier a site appears in the search results list, the more visitors it will receive from the search engine. SEO may target different kinds of search, including image search, local search, and industry-specific vertical search engines.
As an Internet marketing strategy, SEO considers how search engines work and what people search for. Optimizing a website primarily involves editing its content and HTML coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines.
The acronym “SEO” can also refer to “search engine optimizers,” a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term “search engine friendly” may be used to describe web site designs, menus, content management systems and shopping carts that are easy to optimize.
Another class of techniques, known as black hat SEO or Spamdexing, use methods such as link farms and keyword stuffing that degrade both the relevance of search results and the user-experience of search engines. Search engines look for sites that employ these techniques in order to remove them from their indices. From: http://en.wikipedia.org/wiki/Search_engine_optimization

4) Web hosting
a) A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own or lease for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation.

 Service scope
The scope of hosting services varies widely. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web “as is” or with little processing. Many Internet service providers (ISPs) offer this service free to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or cheap. Business web site hosting often has a higher expense.
Single page hosting is generally sufficient only for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, Ruby on Rails, ColdFusion, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL is also highly recommended.
The host may also provide an interface or control panel for managing the Web server and installing scripts as well as other services like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company.
 Hosting reliability and uptime
This section does not cite any references or sources. Please help improve this article by adding citations to reliable sources. Unverifiable material may be challenged and removed. (March 2009)
Multiple racks of servers.
Hosting uptime refers to the percentage of time the host is accessible via the internet. Many providers state that they aim for a 99.9% uptime, but there may be server restarts and planned (or unplanned) maintenance in any hosting environment.
Many providers tie uptime and accessibility into their own service level agreement (SLA). SLAs sometimes include refunds or reduced costs if performance goals are not met.
 Types of hosting
A typical server “rack,” commonly seen in colocation centres.
Internet hosting services can run Web servers; see Internet hosting services.
Hosting services limited to the Web:
Many large companies who are not internet service providers also need a computer permanently connected to the web so they can send email, files, etc. to other sites. They may also use the computer as a website host so they can provide details of their goods and services to anyone interested. Additionally these people may decide to place online orders.
* Free web hosting service: Free web hosting is offered by different companies with limited services, sometimes advertisement-supported web hosting, and is often limited when compared to paid hosting.
* Shared web hosting service: one’s Web site is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be quite extensive. A shared website may be hosted with a reseller.
* Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a provider. Resellers’ accounts may vary tremendously in size: they may have their own virtual dedicated server to a collocated server. Many resellers provide a nearly identical service to their provider’s shared hosting plan and provide the technical support themselves.
* Virtual Dedicated Server: also known as a Virtual Private Server (VPS for short) divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will often be allocated resources based on a one server to many VPSs relationship, however virtualisation may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have root access to their own virtual space. This is also known as a virtual private server or VPS. Customers are sometimes responsible for patching and maintaining the server.
* Dedicated hosting service: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); however, the user typically does not own the server. Another type of Dedicated hosting is Self-Managed or Unmanaged. This is usually the least expensive for Dedicated plans. The user has full administrative access to the box, which means the client is responsible for the security and maintenance of his own dedicated box.
* Managed hosting service: the user gets his or her own Web server but is not allowed full control over it (root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.
* Colocation web hosting service: similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of the web hosting service. In most cases, the colocation provider may provide little to no support directly for their client’s machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes.
* Cloud hosting: is a new type of hosting platform that allows customers powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. Removing single-point of failures and allowing customers to pay for only what they use versus what they could use.
* Clustered hosting: having multiple servers hosting the same content for better resource utilization. Clustered Servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability.
* Grid hosting: this form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
* Home server: usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user’s connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS hostname is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.
Some specific types of hosting provided by web host service providers:
* File hosting service: hosts files, not web pages
* Image hosting service
* Video hosting service
* Blog hosting service
* One-click hosting
* Pastebin Hosts text snippets
* Shopping cart software
 Obtaining hosting
Web hosting is often provided as part of a general Internet access plan; there are many free and paid providers offering these services.
A customer needs to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. Most hosting providers provide Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The webhosting client may want to have other services, such as email for their business domain, databases or multi-media services for streaming media. A customer may also choose Windows as the hosting platform. The customer still can choose from PHP, Perl, and Python but may also use ASP .Net or Classic ASP.
Web hosting packages often include a Web Content Management System, so the end-user doesn’t have to worry about the more technical aspects. These Web Content Management systems are great for the average user, but for those who want more control over their website design, this feature may not be adequate.
Most modern desktop operating systems (Windows, Linux, Mac OS X) are also capable of running web server software, and thus can be used to host basic websites.
One may also search the Internet to find active webhosting message boards and forums that may provide feedback on what type of webhosting company may suit his/her needs. However some of these message boards and forums will require not only registration, but a paid subscription to be able to access the sections and sub forums with such information.
) Domain name
a) A domain name is an identification label to define realms of administrative autonomy, authority, or control in the Internet, based on the Domain Name System (DNS).
Domain names are used in various networking contexts and application-specific naming and addressing purposes. A prominent example are the top-level Internet domains com, net and org.
Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are open for reservation and registration by end-users that wish to connect local area networks to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.
Individual Internet host computers use domain names as host identifiers, or hostnames. Hostnames are the leaf labels in the domain name system usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g., en.wikipedia.org).
Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the DomainKeys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URIs).
An important purpose of domain names is to provide recognizable names to numerically addressed Internet resources. This abstraction allows any resource (e.g., website) to be moved to a different physical location in the address topology of the network, globally or locally in an intranet. Such a move usually requires changing the IP address of a resource and the corresponding translation of this IP address to and from its domain name.
This article primarily discusses the registered domain names, the domain name registered by the domain name registrars to the public. The Domain Name System article discusses the technical facilities and infrastructure of the domain names system and the hostname article deals with specific information about the use of domain names as hostname.

 Allowed character set
Registered domain names are restricted to using the same character set as all other hostnames, as such they typically can use only ASCII letters, numbers and the hyphen (-). The full stop (dot, .) is used to separate DNS labels. Since this rule does not allow the use of other characters commonly found in non-English languages, and does not allow multi-byte characters necessary for most Asian languages, the Internationalized domain name (IDN) system has been developed and is now in testing stage for a group of top-level domains established for this purpose.
The underscore character is frequently used to ensure that a domain name is not recognized as a hostname, as with the use of SVR DNS server records, for example, although some older systems such as NetBIOS did allow it. To avoid confusion and for other reasons, domain names with underscores in them are sometimes used where hostnames are required.
Domain names are often referred to simply as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use.
The following example illustrates the difference between a URL (Uniform Resource Locator) and a domain name:
Domain name: www.example.net
Registered domain name: example.net
As a general rule, the IP address and the server name are interchangeable. For most Internet services, the server will not have any way to know which was used. However, the explosion of interest in the Web means that there are far more Web sites than servers. To accommodate this, the hypertext transfer protocol (HTTP) specifies that the client tells the server which name is being used. This way, one server with one IP address can provide different sites for different domain names. This feature goes under the name virtual hosting and is commonly used by web hosts.
For example, as referenced in RFC 2606 (Reserved Top Level DNS Names), the server at IP address 18.104.22.168 handles all of the following sites:
 Top-level domains
Every domain name ends in a top-level domain (TLD) or first-level domain name, which is always either one of a small list of generic names (three or more characters), or a two-character territory code based on ISO-3166 (there are few exceptions and new codes are integrated case by case). The generic top-level domain (gTLD) extensions are:

 Second-level and lower level domains
Below the top-level domains in the domain name hierarchy are the second-level domain (SLD) names. These are the names directly to the left of .com, .net, and the other top-level domains. As an example, in the domain en.wikipedia.org, wikipedia is the second-level domain.
Next are third-level domains, which are written immediately to the left of a second-level domain. There can be fourth- and fifth-level domains, and so on, with virtually no limitation. An example of a working domain with four domain levels is www.sos.state.oh.us. The www preceding the domains is a host name of the World-Wide Web server. Each level is separated by a dot, or period symbol. ‘sos’ is said to be a sub-domain of ‘state.oh.us’, and ‘state’ a sub-domain of ‘oh.us’, etc. In general, subdomains are domains subordinate to their parent domain. An example of very deep levels of subdomain ordering are the IPv6 reverse resolution DNS zones, e.g., 22.214.171.124.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa, which is the reverse DNS resolution domain for the IP address of a loopback interface, or the localhost name.
Second-level (or lower-level, depending on the established parent hierarchy) domain names are often created based on the name of a company (e.g., microsoft.com), product or service (e.g., gmail.com). Below these levels, the next domain name component has been used to designate a particular host server. Therefore, ftp.wikipedia.org might be an FTP server, www.wikipedia.org would be a World Wide Web server, and mail.wikipedia.org could be an email server, each intended to perform only the implied function. Modern technology allows multiple physical servers with either different (cf. load balancing) or even identical addresses (cf. anycast) to serve a single hostname or domain name, or multiple domain names to be served by a single computer. The latter is very popular in Web hosting service centers, where service providers host the websites of many organizations on just a few servers.
 Official assignment
The Internet Corporation for Assigned Names and Numbers (ICANN) has overall responsibility for managing the DNS. It administers the root domain, delegating control over each TLD to a domain name registry. For ccTLDs, the domain registry is typically installed by the government of that country. ICANN has a consultation role in these domain registries but cannot regulate the terms and conditions of how domain names are delegated in each of the country-level domain registries. On the other hand, the generic top-level domains (gTLDs) are governed directly under ICANN, which means all terms and conditions are defined by ICANN with the cooperation of each gTLD registry.
Domain names are often seen in analogy to real estate in that (1) domain names are foundations on which a website (like a house or commercial building) can be built and (2) the highest “quality” domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, search engine optimization, and many other criteria.
A few companies have offered low-cost, below-cost or even cost-free domain registrations with a variety of models adopted to recoup the costs to the provider. These usually require that domains be hosted on their website within a framework or portal that includes advertising wrapped around the domain holder’s content, revenue from which allows the provider to recoup the costs. Domain registrations were free of charge when the DNS was new. A domain holder (often referred to as a domain owner) can give away or sell infinite number of subdomains under their domain name. For example, the owner of example.edu could provide subdomains such as foo.example.edu and foo.bar.example.edu to interested parties.

As domain names became interesting to marketers because of their advertising and marketing potential, rather than just being used to label Internet resources in a technical fashion, they began to be used in manners that in many cases did not reflect the intended purpose of the label of their top-level domain. As originally planned, the structure of domain names followed a hierarchy in which the TLD indicated the type of organization (commercial, governmental, etc.), and addresses would be nested down to third, fourth, or further levels to express complex structures, where, for instance, branches, departments and subsidiaries of a parent organization would have addresses in subdomains of the parent domain. Also, hostnames were originally intended to correspond to actual physical machines on the network, generally with only one name per machine.
As the World Wide Web became popular, site operators frequently wished to have memorable addresses, regardless of whether they fit properly into the structure; thus, because the .com domain was the most popular and therefore most prestigious, even noncommercial sites began to obtain domains directly within that gTLD, and many sites desired second-level domain names in .com, even if they were already part of a larger entity where a subdomain would have been logical (e.g., abcnews.com instead of news.abc.com).
Shorter, and therefore more memorable, domain names are thought to have more appeal. As a convenience methods were implemented to reduce the amount of typing required when entering a web site address into the location field of a web browser. A website found at ”http://www.example.org” will often be advertised without the http://, since the HTTP protocol is implicitly assumed when referring to web sites. In many cases, web sites can be also be reached by omitting the www prefix, as in this given example. This feature is usually implemented in DNS by the website administrator. In the case of a .com, the website can sometimes be reached by just entering example (depending on browser versions and configuration settings, which vary in how they interpret incomplete addresses).
The popularity of domain names also led to uses which were regarded as abusive by established companies with trademark rights; this has become known as cybersquatting, in which a person registers a domain name that resembles a trademark in order to profit from visitors looking for that address. To combat this, various laws and policies were enacted to allow abusive registrations to be forcibly transferred, but these were sometimes themselves abused by overzealous companies committing reverse domain hijacking against domain users who had legitimate grounds to hold their names. Such legitimate uses could include the use of generic words that are contained within a trademark, but used in a particular context within the trademark, or their use in the context of fan or protest sites with free speech rights of their own.
As of 2008, the four major Registrars have all sub-contracted their expiring domain lists to certain reseller and auctioneer partnerships, for the purpose of keeping the domain name at the original registrar and continuing to extract revenue off the renewal of premium registered names. Since this policy is not explicitly banned at ICANN, the practice has become more commonplace and as a result, complaints from individual registrants about losing their domains has tracked higher over the past two years .
Laws that specifically address domain name conflicts include the Anticybersquatting Consumer Protection Act in the United States and the Trademarks Act of 1999 in India. Alternatively, domain registrants are bound by contract under the UDRP to comply with mandatory arbitration proceedings should someone challenge their ownership of a domain name.
Often email phishing scams will abuse subdomain names to appear to be a legitimate site. For instance, an email might purport to be from Bank of America, and include a link to a fake login screen hosted on http://www.bankofamerica.com.abc.def.ghi.jkl In this case, the actual domain is ghi.jkl, but appears at first glance to be bankofamerica.com.
 Generic domain names—problems arising from unregulated name selection
Within a particular TLD, parties are generally free to register an undelegated domain name on a first come, first served basis, resulting in Harris’s lament, all the good ones are taken. For generic or commonly used names, this may sometimes lead to the use of a domain name which is inaccurate or misleading. This problem can be seen with regard to the ownership or control of domain names for a generic product or service. By way of illustration, there has been tremendous growth in the number and size of literary festivals around the world in recent years. In the current context, a generic domain name such as literary.org is available to the first literary festival organization that is able to obtain the registration, even if the festival in question is very young or obscure. Some critics argue that there is greater amenity in reserving such domain names for the use of, for example, a regional or umbrella grouping of festivals. Related issues may also arise in relation to noncommercial domain names.
 Unconventional domain names
Due to the rarity of one-word dot-com domain names, many unconventional domain names, domain hacks, have been created. They make use of the top-level domain as an integral part of the Web site’s title. Two popular domain hack Web sites are cr.yp.to and blo.gs, which spell out “crypto” and “blogs”, respectively.
Unconventional domain names are also used to create unconventional email addresses. Non-working examples that spell ‘James’ are email@example.com and firstname.lastname@example.org, which use the domain names m.es (of Spain’s .es) and mes.com, respectively.
 Premium domain names
In the business of marketing domain names, “premium” domain names are often valuable, and have particular characteristics that are used in in the domain appraisal process. For example, the names are short, memorable, may contain words that are regularly searched on search engines, and/or keywords that help the domain name gain a higher ranking on search engines. They may contain generic words, so the domain has more than one meaning.
 Resale of domain names
The business of resale of previously registered domain names is known as the “domain aftermarket”.
Various factors influence the perceived value or market value of a domain name. They include 1) the natural or “organic” traffic that can be attributed to web surfers typing in a domain name in their web browser as opposed to doing a search for the site through a search engine. 2) Branding Opportunity. The ability to have a term recognized and easily recalled as a brand for a company or entity. 3) Re-sale value. The ability to spot trends and predict the value of a name based on its length (short is preferred), clarity, and commercial use. The word “loan” is far more valuable than the word “sunshine”.
Generic domain names have sprung up in the last decade. Certain domains, especially those related to business, gambling, pornography, and other commercially lucrative fields of digital world trade have become very much in demand to corporations and entrepreneurs due to their importance in attracting clients.
There are disputes about the high values of domain names claimed and the actual cash prices of many sales such as Business.com. Another high-priced domain name, sex.com, was stolen from its rightful owner by means of a forged transfer instruction via fax. During the height of the dot-com era, the domain was earning millions of dollars per month in advertising revenue from the large influx of visitors that arrived daily. The sex.com sale may have never been final as the domain is still with the previous owner. Also, that sale was not just a domain but an income stream, a web site, a domain name with customers and advertisers, etc. Two long-running U.S. lawsuits resulted, one against the thief and one against the domain registrar VeriSign . In one of the cases, Kremen v. Network Solutions, the court found in favor of the plaintiff, leading to an unprecedented ruling that classified domain names as property, granting them the same legal protections. In 1999, Microsoft traded the name Bob.com with internet entrepreneur Bob Kerstein for the name Windows2000.com which was the name of their new operating system. 
One of the reasons for the value of domain names is that even without advertising or marketing, they attract clients seeking services and products who simply type in the generic name. This is known as Direct Navigation or Type-in Traffic. Furthermore, generic domain names such as movies.com (now owned by Disney) or Books.com (now owned by Barnes & Noble) are extremely easy for potential customers to remember, increasing the probability that they become repeat customers or regular clients. In the case of Movies.com, Disney has built a stand-alone portal featuring branded content. More and more large brands are beginning to employ a more comprehensive domain strategy featuring a portfolio of thousands of domains, rather than just one or two.
Although the current domain market is nowhere as strong as it was during the dot-com heyday, it remains strong and is currently experiencing solid growth again.  Annually tens of millions of dollars change hands in connection with the resale of domains. Large numbers of registered domain names lapse and are deleted each year. On average, more than 25,000 domain names drop (are deleted) every day.
It is important to remember that a domain (name, address) must be valued separately from the website (content, revenue) that it is used for. The high prices have usually been paid for the revenue that was generated from the website at the domain’s address (URL.). The intrinsic value of a domain is the registration fee. It is difficult to appraise a current market value for a domain. The Fair Market Value of a domain can be anything from nearly nothing to millions of dollars. Factors involved may include previous sales data of similar domains, however a single letter difference can completely alter the value. The value of the domain (or any sum resp. division etc.) are usually added to the current or expected revenue from the web content (advertising, sales, etc.). The price of a domain (name + ext.) should not be confused with that of a website (content + revenue).
An estimate by an appraiser is always the addition of what they would like a domain to be worth together with the effective/expected/desired revenue from the web content. Some people put value on the length of the SLD (name) and other people prefer description capability, but the shorter an SLD is, the less descriptive it can be. Also, if short is crucial, then the TLD (extension) should be short too. It is less realistic to get a domain like LL.travel or LL.mobi than a domain travel. LL or mobi. LL. This illustrates the relativity of domain value estimation. It is safe to say that the revenue of web (content) can be easily stated, but that the value of a domain (SLD.TLD aka name.ext) is a matter of opinion and preference. In the end, however, any sale depends on the expectations of the domain seller and the domain buyer.
A webmaster creating a new web site either buys the domain name directly from a domain name registrar, or indirectly from a domain name registrar through a domainer. People who buy and sell domain names are known as domainers. People who sell value estimation services are known as appraisers.
 Domain aftermarket prices and trends
Domain name sales occurring in the aftermarket are frequently submitted to the DN journal. The sales are listed weekly and include the top aftermarket resellers which include but are not limited to Sedo, Traffic (auctions), Afternic, NameJet, Moniker and private sales.
To date, and according to Guinness World Records and MSNBC, the most expensive domain name sales on record as of 2004 were:
* Business.com for $7.5 million in December 1999
* AsSeenOnTv.com for $5.1 million in January 2000
* Altavista.com for $3.3 million in August 1998
* Wine.com for $2.9 million in September 1999
* CreditCards.com for $2.75 million in July 2004
* Autos.com for $2.2 million in December 1999
The week ending January 27, 2008, DNJournal reported that CNN, a cable news channel purchased iReport.com for $750,000. This signifies another turning point in domain name sales. This name has neither organic traffic, nor does it have a dictionary term alone. Instead it is a highly brandable domain name utilizing the second most popular prefix for a “dictionary” and commercial word.
 Popular domain prefixes – “E” and “I”
In addition to a domain placing value on the shortness of the word, ease in spelling, commercial appeal, and organic capacity to generate natural traffic, today’s domain names are being valued for the branding potential. The domain name sale iReport although not an organic or dictionary term alone, is actually preferred as a highly brandable term, in that it is has a popular pre-fix “i” which indicates the “report” to be online.
The prefixes and dashes between words were once considered second, but now due to brandability, if the term is a commercial term, a prefix is often preferred. Example eLoans markets with an e to indicate to its potential customers that a loan may be obtained online.
The two primary prefixes are “E”, for electronic, and “I”, for Internet. Both indicate the word or phrase to be accessible online. Because of that, in terms of branding, an i or e combined with a commercial term are highly desirable. In domain sales typically an e has been preferred, and i slightly less in terms of demand. eBrooklyn sold for approximately $2500 whereas once it would have been available to register at the price of a domain name (which ranges from $8 to $30 us dollars depending on the registrar). The rapidly increasing use of prefixes in conjunction with main dictionary and or commercial terms is here and for some predominantly internet based companies, or high technology, high profile companies, the prefix is now preferred.
One of the details that make a domain with a prefix more valuable for a brand, is the ability to simply promote the name without the use of “.com” in the promotion. If a domain owner had report.com he would be forced to use the .com to indicate it was on the net at that address, however a domain name with a one letter prefix does not need to use the “.com”.
Someone could promote “iReport” as a brand, and assuming it was a world class brand, visitors would know they could find it at “iReport.com without seeing the .com. However if it was a .net, it would be wise to state iReport.net. This option to simply state the name of the company or entity is particularly valuable in that it is brief and clear in indicating that a report can be either made or found on the “i”nternet.
eLoans similarly does not have to state “eLoans.com”. eLoans, in the minds of most is clearly an online entity offering electronic loan applications.
Some alternative domains that avoid the use of “.com” in their promotion are “WebMD” as the word web as a prefix suffice to indicate the information is online and likely at a .com extension.
 Branding with a domain name
Brands are greatly affected by the ability of the company to obtain the matching domain name. If a company builds a brand around a name to which it does not own the domain name, it can end up directing traffic to another domain owner’s site. If it is a competitor, this would be a problem.
Today’s advertising development of a great brand is strictly confined to the availability to synchronize the brand with a domain name. Any confusion might result in a competitor gaining valuable internet traffic and possible customers.
 Domain name confusion
Intercapping is often used to emphasize the meaning of a domain name. However, DNS names are case-insensitive, and some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com, which can be misread as whore presents. Similarly, a therapists’ network is named therapistfinder.com. Another example is powergenitalia.com, the website of an Italian power generator company. In such situations, the proper meaning may be clarified by use of hyphens in the domain name. For instance, Experts Exchange, the programmers’ site, for a long time used expertsexchange.com, but ultimately changed the name to experts-exchange.com.
Leo Stoller threatened to sue the owners of StealThisEmail.com on the basis that, when read as stealthisemail.com, it infringed on claimed (but invalid) trademark rights to the word “stealth”.
4) Online shopping cart:
a) A shopping cart is a piece of software that acts as an online store’s catalog and ordering process. Typically, a shopping cart is the interface between a company’s Web site and its deeper infrastructure, allowing consumers to select merchandise; review what they have selected; make necessary modifications or additions; and purchase the merchandise.
Shopping carts can be sold as independent pieces of software so companies can integrate them into their own unique online solution, or they can be offered as a feature from a service that will create and host a company’s e-commerce site.
b)Shopping cart software is software used in e-commerce to assist people making purchases online, analogous to the American English term ‘shopping cart’. In British English it is generally known as a shopping basket, almost exclusively shortened on websites to ‘basket’.
The software allows online shopping customers to place items in the cart. Upon checkout, the software typically calculates a total for the order, including shipping and handling (i.e. postage and packing) charges and the associated taxes, as applicable.

 Technical definition
These applications typically provide a means of capturing a client’s payment information, but in the case of a credit card they rely on the software module of the secure gateway provider, in conjunction with the secure payment gateway, in order to conduct secure credit card transactions online.
Some setup must be done in the HTML code of the website, and the shopping cart software must be installed on the server which hosts the site, or on the secure server which accepts sensitive ordering information. E-shopping carts are usually implemented using HTTP cookies or query strings. In most server based implementations however, data related to the shopping cart is kept in the Session object and is accessed and manipulated on the fly, as the user selects different items from the cart. Later at the process of commit, the information is accessed and an order is generated against the selected item thus clearing the shopping cart.
Although the most simple shopping carts strictly allow for an item to be added to a basket to start a checkout process (e.g. the free PayPal shopping cart), most shopping cart software actually provides additional features that an Internet merchant uses to fully manage an online store. Data (products, categories, discounts, orders, customers, etc.) is normally stored in a database and accessed in real time by the software.
Shopping Cart Software is also known as e-commerce software, e-store software, online store software or storefront software.
Shopping cart software typically consists of two components:
* Storefront: the area of the Web store that is accessed by visitors to the online shop. Category, product, and other pages (e.g. search, best sellers, etc.) are dynamically generated by the software based on the information saved in the store database. The look of the storefront can normally be changed by the store owner so that it merges with the rest of the Web site (i.e. with the pages not controlled by the shopping cart software in use on the store).
* Administration: the area of the Web store that is accessed by the merchant to manage the online shop. The amount of store management features changes depending on the sophistication of the shopping cart software chosen by the merchant, but in general a store manager is able to add and edit products, categories, discounts, shipping and payment settings, etc. Order management features are also included in many shopping cart programs. The administration area can be:
o Web-based (accessed through a Web browser)
o Desktop-based (a desktop application that runs on the user’s computer and then transfers changes to the storefront component).
 Licensed vs. Hosted Shopping Carts
Shopping cart software can be generally categorized into two main categories.
* Licensed software: The software is downloaded and then installed on a Web server. This is most often associated with a one-time fee, although there are many free products available as well. The main advantages of this option are that the merchant owns a license and therefore can host it on any Web server that meets the server requirements, and that the source code can often be accessed and edited to customize the application.
* Hosted service: The software is never downloaded, but rather is provided by a hosted service provider and is generally paid for on a monthly/annual basis; also known as the application service provider (ASP) software model. Some of these services also charge a percentage of sales in addition to the monthly fee. This model often has predefined templates that a user can choose from to customize their look and feel. In this model users typically have less ability to modify or customize the software with the advantage of having the vendor continuously keep the software up to date for security patches as well as adding new features added.
Marketing is an integrated communications-based process through which individuals and communities discover that existing and newly-identified needs and wants may be satisfied by the products and services of others.
Marketing is defined by the American Marketing Association as the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.  The term developed from the original meaning which referred literally to going to market, as in shopping, or going to a market to buy or sell goods or services.
Marketing practice tends to be seen as a creative industry, which includes advertising, distribution and selling. It is also concerned with anticipating the customers’ future needs and wants, which are often discovered through market research. Seen from a systems point of view, sales process engineering views marketing as a set of processes that are interconnected and interdependent with other functions, whose methods can be improved using a variety of relatively new approaches.
Marketing is influenced by many of the social sciences, particularly psychology, sociology, and economics. Anthropology and neuroscience are also small but growing influences. Market research underpins these activities. Through advertising, it is also related to many of the creative arts. The marketing literature is also infamous for re-inventing itself and its vocabulary according to the times and the culture.

6) Data Base
A database is a structured collection of records or data that is stored in a computer system. The structure is achieved by organizing the data according to a database model. The model in most common use today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships.
7) Online advertising
Online advertising is a form of promotion that uses the Internet and World Wide Web for the expressed purpose of delivering marketing messages to attract customers. Examples of online advertising include contextual ads on search engine results pages, banner ads, Rich Media Ads, Social network advertising, online classified advertising, advertising networks and e-mail marketing, including e-mail spam.

 Competitive advantage over traditional advertising
One major benefit of online advertising is the immediate publishing of information and content that is not limited by geography or time. To that end, the emerging area of interactive advertising presents fresh challenges for advertisers who have hitherto adopted an interruptive strategy.
Another benefit is the efficiency of advertiser’s investment. Online advertising allows for the customization of advertisements, including content and posted websites. For example, AdWords and AdSense enable ads shown on relevant webpages or aside of search results of pre-chosen keywords. Another is the payment method. Whatever purchasing variation is selected, the payment is usually relative with audiences’ response.
 Purchasing variations
The three most common ways in which online advertising is purchased are CPM, CPC, and CPA.
* CPM (Cost Per Impression) is where advertisers pay for exposure of their message to a specific audience. CPM costs are priced per thousand impressions, or loads of an advertisement. However, some impressions may not be counted, such as a reload or internal user action. The M in the acronym is the Roman numeral for one thousand.
* CPV (Cost Per Visitor) or (Cost per View in the case of Pop Ups and Unders) is where advertisers pay for the delivery of a Targeted Visitor to the advertisers website.
* CPC (Cost Per Click) is also known as Pay per click (PPC). Advertisers pay each time a user clicks on their listing and is redirected to their website. They do not actually pay for the listing, but only when the listing is clicked on. This system allows advertising specialists to refine searches and gain information about their market. Under the Pay per click pricing system, advertisers pay for the right to be listed under a series of target rich words that direct relevant traffic to their website, and pay only when someone clicks on their listing which links directly to their website. CPC differs from CPV in that each click is paid for regardless of whether the user makes it to the target site.
* CPA (Cost Per Action) or (Cost Per Acquisition) advertising is performance based and is common in the affiliate marketing sector of the business. In this payment scheme, the publisher takes all the risk of running the ad, and the advertiser pays only for the amount of users who complete a transaction, such as a purchase or sign-up. This is the best type of rate to pay for banner advertisements and the worst type of rate to charge. Similarly, CPL (Cost Per Lead) advertising is identical to CPA advertising and is based on the user completing a form, registering for a newsletter or some other action that the merchant feels will lead to a sale. Also common, CPO (Cost Per Order) advertising is based on each time an order is transacted.
* Cost per conversion Describes the cost of acquiring a customer, typically calculated by dividing the total cost of an ad campaign by the number of conversions. The definition of “Conversion” varies depending on the situation: it is sometimes considered to be a lead, a sale, or a purchase.
* CPE (Cost Per Engagement) is a form of Cost Per Action pricing first introduced in March 2008. Differing from cost-per-impression or cost-per-click models, a CPE model means advertising impressions are free and advertisers pay only when a user engages with their specific ad unit. Engagement is defined as a user interacting with an ad in any number of ways.
Though, as seen above, the large majority of online advertising has a cost that is brought about by usage or interaction of an ad, there are a few other methods of advertising online that only require a one time payment. The Million Dollar Homepage is a very successful example of this. Visitors were able to pay $1 per pixel of advertising space and their advert would remain on the homepage for as long as the website exists with no extra costs.
* Floating ad: An ad which moves across the user’s screen or floats above the content.
* Expanding ad: An ad which changes size and which may alter the contents of the webpage.
* Polite ad: A method by which a large ad will be downloaded in smaller pieces to minimize the disruption of the content being viewed
* Wallpaper ad: An ad which changes the background of the page being viewed.
* Trick banner: A banner ad that looks like a dialog box with buttons. It simulates an error message or an alert.
* Pop-up: A new window which opens in front of the current one, displaying an advertisement, or entire webpage.
* Pop-under: Similar to a Pop-Up except that the window is loaded or sent behind the current window so that the user does not see it until they close one or more active windows.
* Video ad: similar to a banner ad, except that instead of a static or animated image, actual moving video clips are displayed.
* Map ad: text or graphics linked from, and appearing in or over, a location on an electronic map such as on Google Maps.
* Mobile ad: an SMS text or multi-media message sent to a cell phone.
In addition, ads containing streaming video or streaming audio are becoming very popular with advertisers.
 E-mail advertising
Legitimate Email advertising or E-mail marketing is often known as “opt-in e-mail advertising” to distinguish it from spam.
 Affiliate marketing
Main article: Affiliate marketing
Affiliate marketing is a form of online advertising where advertisers place campaigns with a potentially large number of small (and large) publishers, whom are only paid media fees when traffic to the advertiser is garnered, and usually upon a specific measurable campaign result (a form, a sale, a sign-up, etc). Today, this is usually accomplished through contracting with an affiliate network.
Affiliate marketing was an invention by CDNow.com in 1994 and was excelled by Amazon.com when it launched its Affiliate Program, called Associate Program in 1996. The online retailer used its program to generate low cost brand exposure and provided at the same time small websites a way to earn some supplemental income.
 Contextual advertising
Many advertising networks display graphical or text-only ads that correspond to the keywords of an Internet search or to the content of the page on which the ad is shown. These ads are believed to have a greater chance of attracting a user, because they tend to share a similar context as the user’s search query. For example, a search query for “flowers” might return an advertisement for a florist’s website.
Another newer technique is embedding keyword hyperlinks in an article which are sponsored by an advertiser. When a user follows the link, they are sent to a sponsor’s website.
 Behavioral targeting
In addition to contextual targeting, online advertising can be targeted based on a user’s past clickstream. For example, if a user is known to have recently visited a number of automotive shopping / comparison sites based on clickstream analysis enabled by cookies stored on the user’s computer, that user can then be served auto-related ads when they visit other, non-automotive sites.
 Ads and malware
There is also class of advertising methods which may be considered unethical and perhaps even illegal. These include external applications which alter system settings (such as a browser’s home page), spawn pop-ups, and insert advertisements into non-affiliated webpages. Such applications are usually labeled as spyware or adware. They may mask their questionable activities by performing a simple service, such as displaying the weather or providing a search bar. Some programs are effectively trojans. These applications are commonly designed so as to be difficult to remove or uninstall. The ever-increasing audience of online users, many of whom are not computer-savvy, frequently lack the knowledge and technical ability to protect themselves from these programs.
 Ad server market structure
Given below is a list of top ad server vendors in 2008 with figures in millions of viewers published in a Attributor survey.
Vendor Ad viewers
It should be noted that Google acquired DoubleClick in 2007 for a consideration of $3,100 million. The above survey was based on a sample of 68 million domains
a) Google AdSense is a program in which enterprises can display Google advertisements on Web sites and earn revenue from hits that generate traffic for the Google search engine s. Google AdSense represents businesses of all sizes worldwide in multiple languages. AdSense is a refinement and expansion of the concept behind banner -ad sharing arrangements that have been in use for years.
AdSense delivers targeted advertisments to participants’ Web sites. Google search boxes can be placed on Web pages, generating text ads targeted to search results produced by visitors’ search input. The Google algorithm s are designed to interpret context in such a way that irrelevant results are discarded and only those most likely to produce revenue are delivered.
Google reviews ads using language filters and professional linguists to prevent the display of inappropriate text or content and to ensure that all material conforms to professional editorial and ethical standards. Competitive advertisements can be blocked and default ads can be created or selected.
b) AdSense is an advertisement application run by Google. Website owners can enroll in this program to enable text, image, and more recently, video advertisements on their websites. These advertisements are administered by Google and generate revenue on either a per-click or per-impression basis. Google beta tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering (also owned by Google).[

Google uses its Internet search technology to serve advertisements based on website content, the user’s geographical location, and other factors. Those wanting to advertise with Google’s targeted advertisement system may enroll through AdWords. AdSense has become a popular method of placing advertising on a website because the advertisements are less intrusive than most banners, and the content of the advertisements is often relevant to the website.
Many websites use AdSense to monetize their content. AdSense has been particularly important for delivering advertising revenue to small websites that do not have the resources for developing advertising sales programs and sales people. To fill a website with advertisements that are relevant to the topics discussed, webmasters implement a brief script on the websites’ pages. Websites that are content-rich have been very successful with this advertising program, as noted in a number of publisher case studies on the AdSense website.
Some webmasters invest significant effort into maximizing their own AdSense income. They do this in three ways:
1. They use a wide range of traffic-generating techniques, including but not limited to online advertising.
2. They build valuable content on their websites that attracts AdSense advertisements, which pay out the most when they are clicked.
3. They use text content on their websites that encourages visitors to click on advertisements. Note that Google prohibits webmasters from using phrases like “Click on my AdSense ads” to increase click rates. The phrases accepted are “Sponsored Links” and “Advertisements”.
The source of all AdSense income is the AdWords program, which in turn has a complex pricing model based on a Vickrey second price auction. AdSense commands an advertiser to submit a sealed bid (i.e., a bid not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid.
The underlying technology behind AdSense was derived originally from WordNet, Simpli (a company started by the founder of Wordnet, George A. Miller), and a number of professors and graduate students from Brown University, including James A. Anderson, Jeff Stibel, and Steve Reiss. A variation of this technology utilizing WordNet was developed by Oingo, a small search engine company based in Santa Monica founded in 1998 by Gilad Elbaz and Adam Weissman. Oingo changed its name to Applied Semantics in 2001, which was later acquired by Google in April 2003 for US$102 million.
 AdSense for Feeds
In May 2005, Google announced a limited-participation beta version of AdSense for Feeds, a version of AdSense that runs on RSS and Atom feeds that have more than 100 active subscribers. According to the Official Google Blog, “advertisers have their ads placed in the most appropriate feed articles; publishers are paid for their original content; readers see relevant advertising—and in the long run, more quality feeds to choose from.”
AdSense for Feeds works by inserting images into a feed. When the image is displayed by a RSS reader or Web browser, Google writes the advertising content into the image that it returns. The advertisement content is chosen based on the content of the feed surrounding the image. When the user clicks the image, he or she is redirected to the advertiser’s website in the same way as regular AdSense advertisements.
AdSense for Feeds remained in its beta state until August 15, 2008, when it became available to all AdSense users.
 AdSense for search
A companion to the regular AdSense program, AdSense for search, allows website owners to place Google search boxes on their websites. When a user searches the Internet or the website with the search box, Google shares any advertising revenue it makes from those searches with the website owner. However the publisher is paid only if the advertisements on the page are clicked: AdSense does not pay publishers for mere searches.
 AdSense for mobile content
AdSense for mobile content allows publishers to generate earnings from their mobile websites using targeted Google advertisements. Just like AdSense for content, Google matches advertisements to the content of a website — in this case, a mobile website.
 AdSense for domains
Adsense for domains allows advertisements to be placed on domain names that have not been developed. This offers domain name owners a way to monetize domain names that are otherwise dormant. Adsense for domains is currently being offered to some users, with plans to make it available to all in stages.
On December 12, 2008, TechCrunch reported that AdSense for Domains is available for all US publishers.
 XHTML compatibility
As of September 2007, the HTML code for the AdSense search box does not validate as XHTML, and does not follow modern principles of website design because of its use of
* non-standard end tags, such as </img> and </input>,
* the attribute checked rather than checked=”checked”,
* presentational attributes other than id, class, or style — for example, bgcolor and align,
* a table structure for purely presentational (i.e., non-tabular) purposes,1 and
* the font tag.2
1: using a table structure for unintended purposes is strongly recommended against by the W3C, but nevertheless does not cause a document to fail validation — there is currently no algorithmic method of determining whether a table is used “correctly” (for displaying tabular data or for displaying elements, that get proportionally wider or narrower when browser window resizes in width without active client side scripting).
2: the font tag is deprecated but does not fail validation in any XHTML standard.
The terms of the AdSense program forbid its affiliates from modifying the code, thus preventing these participants from having valid XHTML websites.
However, a workaround has been found by creating a separate HTML webpage containing only the AdSense advertisement units, and then importing this page into an XHTML webpage with an object tag. This workaround appears to be accepted by Google.
 How AdSense works
* For contextual advertisements, Google’s servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system. (More details are described in the AdSense patent.)
* For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost per mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed.
* For referrals, Google adds money to the advertiser’s account when visitors either download the referred software or subscribe to the referred service. The referral program was retired in August 2008.
* Search advertisements are added to the list of results after the visitor performs a search.
Some webmasters create websites tailored to lure searchers from Google and other engines onto their AdSense website to make money from clicks. These “zombie” websites often contain nothing but a large amount of interconnected, automated content (e.g., a directory with content from the Open Directory Project, or scraper websites relying on RSS feeds for content). Possibly the most popular form of such “AdSense farms” are splogs (spam blogs), which are centered around known high-paying keywords. Many of these websites use content from other websites, such as Wikipedia, to attract visitors. These and related approaches are considered to be search engine spam and can be reported to Google.
A Made for AdSense (MFA) website or webpage has little or no content, but is filled with advertisements so that users have no choice but to click on advertisements. Such pages were tolerated in the past, but due to complaints, Google now disables such accounts.
There have also been reports of Trojan horses engineered to produce counterfeit Google advertisements that are formatted looking like legitimate ones. The Trojan downloads itself onto an unsuspecting computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.
Due to concerns about click fraud, ‘Google AdSense’ has been criticized by some search engine optimization firms as a large source of what Google calls “invalid clicks”, in which one company clicks on a rival’s search engine advertisements to drive up the other company’s costs.
To help prevent click fraud, AdSense publishers can choose from a number of click-tracking programs. These programs display detailed information about the visitors who click on the AdSense advertisements. Publishers can use this to determine whether or not they have been a victim of click fraud. There are a number of commercial tracking scripts available for purchase.
The payment terms for webmasters have also been criticized. Google withholds payment until an account reaches US$100, but many micro content providers require a long time—years in some cases—to build up this much AdSense revenue. However, Google will pay all earned revenue greater than US$10 when an AdSense account is closed.
Many website owners complain that their AdSense accounts have been disabled just before they were supposed to receive their first paycheck from Google. Google claims accounts have been disabled due to click fraud.
Google came under fire when the official Google AdSense Blog showcased the French video website Imineo.com. This website violated Google’s AdSense Program Policies by displaying AdSense alongside sexually explicit material. Typically, websites displaying AdSense have been banned from showing such content. Some sites have been banned for distributing copyright material even when they hold the copyright themselves or are authorized by the copyright holder to distribute the material.
It has been reported that using both AdSense and AdWords may cause a website to pay Google a commission when the website advertises itself
b) AdWords is Google’s flagship advertising product and main source of revenue ($16.4 billion in 2007). AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google’s text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.
Google’s AdWords division is based in Ann Arbor, Michigan, the company’s third-largest facility behind its Mountain View, California, headquarters and New York City office.
Pay-Per-Click advertisements (PPC)
Advertisers specify the words that should trigger their ads and the maximum amount they are willing to pay per click. When a user searches Google’s search engine on www.google.com or the relevant local/national google server (e.g. www.google.fr for France), ads (also known as creatives by Google) for relevant words are shown as “sponsored links” on the right side of the screen, and sometimes above the main search results.
The ordering of the paid-for listings depends on other advertisers’ bids (PPC) and the “quality score” of all ads shown for a given search. The quality score is calculated by historical click-through rates, relevance of an advertiser’s ad text and keywords, an advertiser’s account history, and other relevance factors as determined by Google. The quality score is also used by Google to set the minimum bids for an advertiser’s keywords. The minimum bid takes into consideration the quality of the landing page as well, which includes the relevancy and originality of content, navigability, and transparency into the nature of the business . Though Google has released a list of full guidelines for sites , the precise formula and meaning of relevance and its definition is in part secret to Google and the parameters used can change dynamically.
The auction mechanism that determines the order of the ads has been described as a Generalized second-price auction.  This is claimed to have the property that the participants do not necessarily fare best when they truthfully reveal any private information asked for by the auction mechanism (in this case, the value of the keyword to them, in the form of a “truthful” bid).
 Placement targeted advertisements (formerly Site-Targeted Advertisements)
In 2003 Google introduced site-targeted advertising. Using the AdWords control panel, advertisers can enter keywords, domain names, topics, and demographic targeting preferences, and Google places the ads on what they see as relevant sites within their content network. If domain names are targeted, Google also provides a list of related sites for placement. Advertisers may bid on a cost per impression (CPI) or cost per click (CPC) basis for site targeting .
With placement targeting, it is possible for an ad to take up the entire ad block rather than have the ad block split into 1 to 4 ads, resulting in higher visibility for the advertiser.
The minimum cost-per-thousand impressions bid for placement targeted campaigns is 25 cents. There is no minimum CPC bid, however.
 AdWords distribution
All AdWords ads are eligible to be shown on www.google.com. Advertisers also have the option of enabling their ads to show on Google’s partner networks. The “search network” includes AOL search, Ask.com, and Netscape. Like www.google.com, these search engines show AdWords ads in response to user searches.
The “content network” shows AdWords ads on sites that are not search engines. These content network sites are those that use AdSense, the other side of the Google advertising model. AdSense is used by website owners who wish to make money by displaying ads on their websites. Click through rates on the content network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser’s quality score. It has been reported that using both AdSense and AdWords may cause a website to pay Google a commission when the website advertises itself.
Google automatically determines the subject of pages and displays relevant ads based on the advertisers’ keyword lists. AdSense publishers may select channels to help direct Google’s ad placements on their pages, to better track performance of their ad units. There are many different types of ads you can run across Google’s network, including text ads, image ads (banner ads), local business ads, mobile text ads, and in-page video ads.
Google AdWords’ main competitors are Yahoo! Search Marketing and Microsoft adCenter.
 AdWords account management
To help clients with the complexity of building and managing AdWords accounts search engine marketing agencies and consultants offer account management as a business service. This has allowed organizations without advertising expertise to reach a global, online audience. Google has started the Google Advertising Professionals program to certify agencies and consultants who have met specific qualifications and passed an exam.. Google also provides account management software, called AdWords Editor.
Another useful feature is the My Client Centre available to Google Professionals (even if not yet passed the exam or budget parameters) whereby a Google professional has access and a dashboard summary of several accounts and can move between those accounts without logging in to each account.
Google Click-to-Call was a service provided by Google which allows users to call advertisers from Google search results pages. Users enter their phone number, Google calls them back and connects to the advertiser. Calling charges are paid by Google. It was discontinued in 2007.
The original idea was invented by Bill Gross from Idealab who, in his turn, borrowed it from yellow pages. Google wanted to buy out the idea but the deal would not get closed. Google did not want to give up and launched AdWords in 2000.. AdWords followed Bill Gross’ model to a significant extent. In the course of legal action Google and Idealab settled the dispute.
At first AdWords advertisers would pay a monthly amount, and Google would then set up and manage their campaign. To accommodate small businesses and those who wanted to manage their own campaigns, Google soon introduced the AdWords self-service portal. Starting in 2005 Google provided a campaign management service called Jumpstart  to assist advertisers in setting up their campaigns. However, this service is no longer available, so companies needing assistance must hire a third-party service provider.
In 2005, Google launched the Google Advertising Professional (GAP) Program to certify individuals and companies who have completed AdWords training and passed an exam. Due to the complexity of AdWords and the amount of money at stake, some advertisers hire a consultant to manage their campaigns.
 Legal context
AdWords has generated lawsuits in the area of trademark law and click fraud. In 2006, Google settled a click fraud lawsuit for US$90 million. 
Overture Services, Inc. sued Google for patent infringement in April 2002 in relation to the AdWords service. Following Yahoo!’s acquisition of Overture, the suit was settled in 2004 with Google agreeing to issue 2.7 million shares of common stock to Yahoo! in exchange for a perpetual license under the patent. 
The AdWords system was initially implemented on top of the MySQL database engine. After the system had been launched, management decided to use a commercial database (Oracle) instead. As is typical of applications simultaneously written and tuned for one database, and ported to another, the system became much slower, so eventually it was returned to MySQL. 
Policy and restrictions
As of April 2008 Google AdWords no longer allows for the display URL to deviate from that of the destination URL. Prior to its introduction, Google paid advertisements could feature different landing page URLs to that of what was being displayed on the search network. Google expounds that the policy change stems from both user and advertiser feedback. The concern prompting the restriction change is believed to be the premise on which users clicked advertisements. Users were in some cases, being misled and further targeted by AdWords advertisers.
Google has other restrictions, for example the advertising of a book by Aaron Greenspan called Authoritas: One Student’s Harvard Admissions and the Founding of the Facebook Era, was restricted from advertising on AdWords because it contained the word Facebook in it. Google’s rationale was that it was prohibited from advertising a book which used a trademarked name in its title. 
Google has also come under fire for allowing AdWords advertisers to bid on trademarked keywords. In 2004, Google started allowing advertisers to bid on a wide variety of search terms in the US and Canada, including the trademarks of their competitors and in May 2008 expanded this policy to the UK and Ireland. Advertisers are restricted from using other companies’ trademarks in their advertisement text if the trademark has been registered with Advertising Legal Support team. Google does, however, require certification to run regulated keywords, such as those related to pharmaceuticals keywords, and some keywords, such as those related to gambling and hacking, are not allowed at all. These restrictions may vary by location. From June 2007, Google banned AdWords adverts for student essay writing services. While the move was welcomed by universities, there is no restriction on such sites appearing in the regular Google Search results.
