I'm seeing very low RPC for my Yahoo ads, much less than Google Adsense. Is this the norm now or is it because of the type of ads i'm running?
well, I rather look at any other category which might match little bit with your site content.. change category till you don't get atleast 25 cents.
I've tried changing to a lot of categories. My site is entertainment based so these are probably the most targeted ads. I've tried dating, movies, celebrities, internet, and a few others. Plus, it seems like my ad targeting choices aren't really working that well, as Yahoo changes the ads to stuff like "Cheap Hotel."
Sometimes I think the ad targeting is just a "Suggestion" for the Yahoo algorithms. Other times it works perfectly in my view, but it can show ads for Traveling when I am targetting the Computer category or sub-cat.
