I can't believe this is legitimate. I know Google has a good filtering system, but somehow I suspect a competitor has figured out a loop hole.
Since my affiliate program showed no drastic increase in click-thrus, I had no reason to be alarmed and I didn't check my adword stats for a number of days. And that's all it took. At a rate of $400 a day my bank account is wiped out.
Maybe your ad has found a very relevant content site automatically. Check your ROI too. As long as your clicks are still resulting in the same number of sales/enquiries/etc per click. then its just as simple as setting an upper limit for each campaign until you get a better ad budget due to the extra revenue coming from it.
Ive heard that Google are pretty good at investigating reasons for sharp upturns in clicks and checking for fraud. Best to email them from your adwords control panel.
I'm corresponding with my web host in an attempt to track IP numbers, and then I will seek the necessary authority to press criminal charges.
I've had individuals attack my site before, but Google caught it in the past. This time it apparently squeaked through.
I dont see any evidence to suggest this is related to Adense at all at this stage. It looks like its an automated clickbot from the reports here, and they can target google SERPS just as well, and possible much more easily than adsense sites.
Adwords advertisers can also check if these extra clicks are coming from content or SE sites by checking the breakdown at the bottom of each campaign report page, as long as the clickbot is not spoofing these as well..
That would be much better evidence than any supposition..
So are any adwords advertisers reporting here of these abnormal clicks finding that these extra masses of clicks are also being acompanied by a much higher proportion of content site clicks against SE clicks (or CTR inconsistencies)?
