So I run a blog that is starting to see some significant traffic, I run two leaderboard ads on it one at the top and one at the bottom. After a week of being up I've noticed that the bottom ad is getting about 40 times more clicks than the top one but the the CPC for the top ad is around 3 times more than the ad at the bottom.
Anyways, I made some calculations and figured if I took the top ad off and got the same CPC on the bottom ads as the top I would be roughly trippling my earnings. Is this how Adsense works though? Anyone else done similar tests? Also I know one of the number one rules of Adsense is to make sure you have an ad above the "fold". Am I crazy to not even have one ad at the top of my blog?
Thanks in advance!
