I wonder why some have such huge "clawback" as you say. In my case, it's has never been more than 0.5 % (November was at 0.3%). May be my volume of earning is not big enough to be significant; I am at the "bottom of the 4 digits range" of earning per month from Adsense.
However, my ads are very well dissociated from the content, so I guess that "accidental clicks" are low, but I assume that Google detects these kind of clicks immediately, and don't really count them, or remove them not long after they occurred.
Also, each day, I am disabling ads from advertisers which I feel like are scam. May be part of the monthly clawbacks is related to advertisers who didn't pay? (but I think that advertisers have to feed them adwords account first, before being able to have their ads shown, but may be remains some failure of payments). I also understood that Google is valuing clicks based on different factors, such as the time spent on the site of the advertiser, and actions made by the visitors there, isn't it ? So may be low quality/misleading/disapointing advertisers are hurting afterward, this calculation.
Or may be I am just lucky, and the relation between my visitor's profile, and advertisers one is matching fine.
Good luck anyone for December,
