title: Studying and understanding how Google AdSense works behind the scenes
body: <p>I would like to learn how Google AdSense works in the sense of understanding for an example how that javascript we put on a page loads an iframe (is it an iframe ?) which checks the words on a page and then sends those words and gets back some ads. Does anyone know any good tutorials on this ? I'm not interested in knowing how to use google adsense or what's the logic behind it (so <a href="http://kpfingaz.hubpages.com/hub/How_does_Google_Adsense_work" rel="nofollow">this</a> and <a href="http://www.google.com/support/adsense/bin/static.py?hl=en&amp;page=guide.cs&amp;guide=29574" rel="nofollow">this</a> do not answer my question)</p>
