We first replaced all our adsense ads with yahoo ads around october 2007, it looked great and returned higher eCPMs than adsense did. So we kept yahoo instead of adsense for about three months. Then we received an email from Y last week saying that the manual ad targeting was disabled for our account due to low conversion rates of the clicks we generated. Since that day, our Y earnings dropped close to nothing and we switched back completely to Adsense. Yahoo simply doesn't have the inventory Google has and that sucks big time. I guess for that reason, the manual ad targeting feature didn't allow us to select the exact niche that we are in so we selected a somewhat similar niche, which did paid well but I guess didn't convert well for the advertisers.
