In my personal experience, the only way that you can make any money from the ad networks is if you serve primarily popups, popunders and downloads. In fact, if you don't, you may end up owing money to the ad network.
And if you serve excessive popups or downloads at all, you are in violation of the Adsense TOS.
Site Content Site may not include:
Excessive profanity Hate, violence, racial intolerance, or advocate against any individual, group, or organization Hacking/cracking content Illicit drugs and drug paraphernalia Pornography, adult, or mature content Gambling or casino-related content Excessive advertising Pop-ups that interfere with site navigation or are for downloads
Maybe do some kind of internal advertising? Or reclaim the space for actual content. I think that's what I'm going to try doing, there's lots of little blocks of stuff I'd like to incorporate into my pages.
