Are you using Media on the same page as adsense? I'm just wondering. I've used them, but I haven't seen any earnings. They have such a low return, just like infolinks and kontera. I'm wondering though, if over time if you have seen those earnings rise?
As for adsense, my ads are back to normal, I'm not seeing crazy unrelated ads, but the earnings are still just dragging. I'm down 80% at least. It's making me sick. I'm trying to just go on and keep building the site better and better, but it's difficult not to keep trying to tweak things to see if there is a change. I've gone through about 200 pages and made sure that none of my ads were by menus or covered by lightboxes or anything like that. It's very painful right now.
