I am totally surprised when I checked adsense account just now. The report shows I have earned $64.20 with 170 page views and 90 clicks with in 12 hours today just from a single autoblog. which I have setup 5 months before and haven't touched yet after initial promotion. I was normally earning about $6 per day from that autoblog and ctr used to be about 13% and earning per click about 45 cents. Traffic is not increased very much but ctr is 5 folds and earning per click is also about 2 folds. How this could happen ? Have anyone similar experience ? Could this put my adsense account in risk?
