Google Adsense is a program run by Google that allows publishers in the Google Network of content sites to serve automatic text, image, video or interactive media advertisements, that are targeted to site content and audience.
The Adsense name was originally used by applied semantics, a competitive offering to Adsense and then adopted by Google after Google acquired applied Semantics in April 2003.Applied Semantics was started in 1998 by Gilad Elbazand and Adam Weissman.Google launched its Adsense program, originally named content targeting advertising in March 2003.
Google Adsense is free, simple way, for website publishers of all sizes to earn money by displaying targeted Google ads on their websites.
The advertisements are administered, sorted, and mantained by Google.They can generate revenue on either a per-click or per-impression basis.Adsense is a participant in the AdChoices program, so Adsense ads typically include the triangle shaped AdChoice icon.Adsense has become one of the popular programs that specializes in creating and placing banner advertisemants on a website, because the advertisements are less intrusive and the content of the advertisements are often relevant to the website.
Possibly the most popular form of such " Adsense Farms" are splogs (spam blogs), which are centered around known high-playing keywords.Some webmasters create websites tailored to lure searchers from Google and other engines onto their Adsense website to make money from clicks.

- They build valuable content on their websites that attract Adsense advertisements, which pay out the most when they are clicked.
- They use text content on their websites that encourages visitors to click on their advertisements.
