For some reason today, the clicks on one of our AdSense channels on one site started going unreasonably high with corresponding off the charts kind of revenue showing for those clicks in the AdSense reports. It looks like all the unusual click activity is coming from the UK according to AdSense reporting.
Google Analytics isn't showing the same thing. On Google Analytics our earnings for the day are typical, as is our site traffic. There seems to be no unusual traffic from the UK showing in Analytics.
Our site logs show no unusual activity for the day and I'm not seeing any unusual activity from the UK, either.
We turned off the AdSense ads in the channel that was effected, and even after we've turned them off, the number of clicks and revenue keep going up - by a substantial amount each hour.
I double checked in the AdSense settings and we have that set to allow only sites we specify, and only own our sites are showing there. So it shouldn't be an issue of something scraping our content and putting it on another site with the AdSense code scraped, too.
Has anyone had similar problems and solved them? Is this an AdSense issue that won't affect us? Or is there something out there that AdSense can't detect but Analytics knows not to count?
