can u share the URL (... i know you are shy...but..still)........... may be DP members can do a detailed scan.
Maybe you should simply change the text on your site. Give some more keywords, maybe their density is too low.
I think this will be my last post on this issue since nobody seems to be reading the thread. Again, regardless of content, and even for NO content at all, I get ads in Russian. The site is in English, and previous to one week ago always had relevant ads in English. Something must be wacked in Goog's database causing them to think the domain is Russian language and so they serve Russian ads. I've emailed them for help and got a reply 3 days ago that they are working on it. It's now day 6 of the problem. CTR and earnings remain near zero. Since Goog won't do anything about it I have to implement an Adsense alternative. Too bad, I was getting low double digit daily earnings and they were rising steadily.
