Google uses its Internet search
technology to serve advertisements based on website content, the user's
geographical location, and many other factors. Those wanting to advertise
with Google's targeted advertisement system may enroll through Google AdWords.
AdSense has become one of the popular companies that specializes in
creating and placing banner advertisements on a website, because the
advertisements are less intrusive and the content of the advertisements
is often relevant to the website.
Many websites use AdSense to monetize their content; it is the most popular advertising network. Ad Sense 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 generate revenue with. To fill a website with advertisements that are relevant to the topics discussed, webmasters place a brief HTML code 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. AdSense publishers may only place three ad units per page.
Some webmasters put significant effort into maximizing their own AdSense income. They do this in three ways:
Oingo changed its name to Applied Semantics in 2001, which was later acquired by Google in April 2003.
Google launched its AdSense program in March 2003 and made it public in June of that year. Some advertisers complained that AdSense yielded worse results than AdWords, since it served ads that related contextually to the content on a web page and that content was less likely to be related to a user's commercial desires than search results. For example, someone browsing a blog dedicated to flowers was less likely to be interested in ordering flowers than someone searching for terms related to flowers. As a result, in 2004 Google allowed its advertisers to opt out of the AdSense network.
By early 2005 AdSense accounted for an estimated 15 percent of Google's total revenues.
In 2009, Google AdSense announced that it would now be offering new features, including the ability to "enable multiple networks to display ads".
In February 2010, Google AdSense started using search history in contextual matching to offer more relevant ads.
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.
On December 12, 2008, TechCrunch reported that AdSense for Domains is available for all US publishers.
On February 22, 2012, Google announced that it was shutting down its Hosted AdSense for Domains program.
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 uploads itself onto an unsuspecting user's computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.
There have been numerous complaints reported about the difference in
treatment that a publisher is receiving from Asia against one from the
US.
Due to alleged 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.[citation needed] 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.[citation needed]
Millions of webmasters and website owners depend on revenue generated from Google AdSense but the company can be dishonest and manipulative in reporting in that it provides estimates of revenue earned with a small disclaimer that the finalized earnings may be slightly lower than estimated. However, the amount deducted can be 50% or even 100% (deducted as "invalid clicks"), a gross manipulation of AdSense publishers.
The payment terms for webmasters have also been criticized. Google withholds payment until an account reaches US$100, but many micro content providers[citation needed] 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 and not disabled. On the other side Google bills its customers (API users for example) monthly, in increments as low as a few cents.[citation needed]
Many website owners complain that their AdSense accounts have been disabled just before they were supposed to receive their first paycheck from Google.[citation needed] Google claims accounts have been disabled due to click fraud or forbidden content, but have offered no proof of this.[citation needed] An automated email is sent to the publisher's owner which offers no reasoning, or options but a link to file an appeal.[citation needed] In the email, Google states that "Because we have a responsibility to protect our AdWords advertisers from inflated costs due to invalid activity, we've found it necessary to disable your AdSense account. Your outstanding balance and Google's share of the revenue will both be fully refunded back to the affected advertisers."[citation needed] The revenue generated - whether legitimate or not - is taken, and all complaints are deferred.[26][not in citation given]
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.
It has been reported that using both AdSense and AdWords may cause a website to pay Google a commission when the website advertises itself.
In some cases, AdSense displays inappropriate or offensive ads. For example, in a news story about a terrorist attack in India, an advert was generated for a (presumably non-existent) educational qualification in terrorism.
AdSense uses tracking cookies that are viewed by some users as a threat to privacy. Webmasters that use AdSense must place the appropriate warning in the privacy policy page.

Some webmasters put significant effort into maximizing their own AdSense income. They do this in three ways:
- They use a wide range of traffic-generating techniques, including but not limited to online advertising.
- They build valuable content on their websites that attracts AdSense advertisements, which pay out the most when they are clicked.
- 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".
History
Oingo, Inc., a privately held company located in Los Angeles, was started in 1998 by Gilad Elbaz and Adam Weissman. Oingo developed a proprietary search algorithm that was based on word meanings and built upon an underlying lexicon called WordNet, which was developed over the previous 15 years by researchers at Princeton University, led by George Miller.Oingo changed its name to Applied Semantics in 2001, which was later acquired by Google in April 2003.

Types
AdSense for Content
there are many kinds of way of way nad ideas of posting and targeting ads.The content-based adverts can be targeted for interest or context. The targeting can be CPC (click) or CPM (impression) based. There's no significant difference between CPC and CPM earnings, however CPC ads are more common. There are various ad sizes for available for content ads. The ads can be simple text, image, animated image, flash, video, or rich media ads. At most ad sizes, users can change whether to show both text and multimedia ads or just one of them. As of November 2012, a grey arrow appears beneath AdSense text ads for easier identification.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 Custom Search boxes on their websites. When a user searches the Internet or the website with the search box, Google shares 51% of the 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 regular searches. Web publishers have reported that they also pay a range from $5.67 to $18.42 per click.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. Instead of traditional JavaScript code, technologies such as Java and Objective-C are usedAdSense 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 or not in use. AdSense for domains is currently being offered to all AdSense publishers, but it wasn't always available to all.On December 12, 2008, TechCrunch reported that AdSense for Domains is available for all US publishers.
On February 22, 2012, Google announced that it was shutting down its Hosted AdSense for Domains program.
AdSense for video
AdSense for video allows publishers with video content to generate revenue using ad placements from Google's extensive advertising network including popular YouTube videos.How AdSense works
- The webmaster inserts the AdSense JavaScript code into a webpage.
- Each time this page is visited, the JavaScript code uses inlined JSON to display content fetched from Google's servers.
- 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.
- Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified.
Abuse
Some webmasters create websites tailored to lure searchers from Google and other engines onto their AdSense website to make money from clicks. Such 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 uploads itself onto an unsuspecting user's computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.
