                          AdSense is an
                                  ad serving  
                                 program run by 
                                 Google. Website
                                 owners can 
                                  enroll in this   
                                   program to
                                  enable text, image and, more recently, video advertisements on their sites. These ads are administered by Google and generate revenue on either a per-click or per-thousand-impressions
basis. Google is also currently beta-testing a cost-per-action based service.


Google utilizes its search technology to serve ads based on website content, the user's geographical location, and other factors. Those wanting to advertise with Google's targeted ad system may sign up through AdWords. AdSense has become a popular method of placing advertising on a website because the ads are less intrusive than most banners, and the content of the ads is often relevant to the website.

It currently uses JavaScript code to incorporate the advertisements into a participating site. If it is included on a site which has not yet been crawled by the Mediabot, it will temporarily display advertisements for charitable causes known as public service announcements (PSAs). (Note that the Mediabot is a separate crawler from the Googlebot that maintains Google's search index.)

Many sites use AdSense to monetize their content and some webmasters work hard to maximize 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 sites; content which attracts AdSense ads and which pay out the most when they get clicked.
They use copy on their websites that encourage clicks on ads. Note that Google prohibits people from using phrases like "Click on my AdSense ads" to increase click rates. 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, in that it commands an advertiser to submit a sealed bid (not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid.

AdWords is Google's flagship advertising product, and main source of revenue. 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.

KEYWORD SELECTOR TOOL This tool by Overture allows you to see which is the most popular way people search that word you have in mind. EG, I have an AVON site and I use as keyword "Avon Consultant", but according to the Tool, Avon Consultant was never used as a search word. But "Avon Representative "was. See how crucial is that ! I will never get any hits if I stick with "Avon Consultant".
