Here is a link about how search monetizes when compared to content sites (~ 30 to 1!) http://www.emarketer.com/Article.aspx?R=1007053 http://www.emarketer.com/Article.aspx?R=1007053 As an extension of that, sites which get most of their traffic from search often have the highest ad CPM values because the ad targeting is so relevant on the AdSense ads. And this is true even moreso now that Google is also using the referrer for ad targeting http://adsense.blogspot.com/2010/02/better-contextual-matching.html http://adsense.blogspot.com/2010/02/better-contextual-matchi... Scraper sites do quite well on the ad revenues front because most of the traffic is search driven, and because the content ends up so bad that the ads look all the more appealing.
