What is Google AdSense?
Google AdSense is an advertising program that was launched in the middle of 2003 by Google, the popular search engine. Google acts as an intermediary between a vast number of advertisers and an equally impressive number of website owners.
Advertisers sign up with Google and create text ads that they would like to be displayed. Google displays these ads on the results pages of searches that people conduct from Google.com. The Google AdSenseprogram
allows these advertisements to show up on pages all over the internet.
To see some of the ads themselves, take a look at the sidebar on this
page. The webmaster simply places a special code in their page and Google AdSense takes
care of the rest. Perhaps the most valuable aspect of the system is
that robots (specialized computer programs that scan internet pages)
analyzes pages that ads will be placed on to determine which ads are
most relevant to the page's content
