I logged in today and saw that there were around 80 Clicks on a mere 120 impressions (or some ridiculous CTR order of magnitude around that, those aren't the specific numbers) which would be atypical for almost anyone I would think, which led me to wonder how often does Adsense report erronous numbers? (I believe it's in error anyway) I've noticed that the snapshot (1st page) appears to lag the Advanced Reports but today those two are in agreement. (I've shot off an email to Google asking them as well but no response)
I've noticed that in general if I choose "all time" from the drop down box under the Advanced Reports page, this is the one which gets updated first but of course everything syncs up eventually.
I have seen my numbers change from one day then I check them again a week later and they are different. I am ditching ad sense...payouts per click have dropped dramatically and I am tired of the Google power bs. One too many horror stories I have read about Google taking earning away because they say there were fraud clicks...it is your word against them, and they will are the judge jury and executioner.
I agree with you that they are the petitioners, advocate, judge, jury and excutioner. We should have some kind of appealing mechanism if our memebership is banned.
