I'm curious how Adsense determines the percentage of the fee the advertiser pays Google for what is paid to the site owner carrying Adsense ads? For instance, if an advertiser pays $5.00 per click for an ad, and my site carries the ad, and one my users clicks on the ad, what part of the $5.00 do I get?
Is there any formula to determine this? Or is it secret?
Thanks!
