How does AdSense work-part one?
Google Adsense provides you with a number of ad formats - image or text based. Implementing AdSense is very easy. You specify your preferences and JavaScript is then generated which you copy and paste into your page source code where you would like the ad to display. You can use the same JavaScript code on any of your websites.
Each time the page is viewed, the AdSense bot queries Google. If the page isn't listed in Google or has changed,
then the bot will scan the page to determine what ads to display. The Adsense bot can be easily identified in your
server logs - it's called Mediapartners-Google/2.1
