what is Google Adsense

AdSense is an ad seving application run by google inc. website owners can enroll in this program to enable text, image and more recently, video 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 save 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 website because the adbertisements are less intrusive than most banners and the content of the advertisements is often relevant to the website.

currently, AdSense uses javascripst code to incorporate the advertisements into a participating website. If the advertisements are included on a website that has not yet been crawled by the mediabot, AdSense will temporarily display advertisements for charitable causes, also knows as public service announcements. The mediabot is diffents from the Googlebot, which maintains Google's search index.

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 relevant to 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 maximazing 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 visitirs 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 aution. AdSense commands an advertiser to submit a sealed bid. Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid.
