Lets face it, the biggest down fall of Adsense is not being in complete control of the ad space and giving it all up to Google. Even if you have targeted keywords, rich and dynamic content and a good healthy flow of traffic you can get pwned by the fill rate. Is there a way to fix his?
ugh. Fill Rate is the how often Google actually matches ads to your sites content. When making a google ad you have the choice of adding a 'url' to serve different ads. Anyone have another ad program that they use in that instance?
