My blog got about 1000 pageviews this month with about 70-80% of traffic coming from google. 0% clickthrough. Normally I have 0.8-1% ctr. Furthermore, my statcounter shows at least 9 clicks from 8 different people, 6 of which were first time vistitors from google search, but none of them is credited or even registered by adsense. If these clicks are invalid, shouldnt they show up at least as clicks with $0 pay? Last month I got clickbombed, somebody was clicking my ads for 3 hours, but none of those clicks showed up also. So whats going on?
