I hate to say it, but I've now removed Yahoo ads from all the pages on my site where I was testing them except for one low traffic page just to keep my account open.

In the few days since I did this, and replaced them with Google ads, the targetting has been 1000% better, the click though rate has gone up by a factor of between 5x and 10x and the page revenues have gone up by anything from 2x to 4x.

I've love to see a viable alternative to AdSense so that I could diversify my contextual based advertsing, but Yahoo is simply not up to the task right now. I'm certain that my experiment with Yahoo has actually cost me money.

Sorry guys. Nice try but it just makes no sense for me to run Yahoo ads on my site.
