My pages are totally in English. But the link unit turns out to be Russian or something and not targeted at all. What is this all about, it's been half a day like this at least I suppose.
No, but it's functioning correctly until half a day before. Tried to insert new ads code from Adsense panel, problem still. Now I have to erase out all ads code so that my visitors won't panic..
That simply means there are no ads available for your keywords. A reader in this case can type a keyword and click. hope that helps.
Thanks for reply, but don't think so. Half a day before, enough related ads displayed. Check this out http://forums.digitalpoint.com/showthread.php?goto=newpost&t=358569
