I think you are having very low paying keywords, generally I got it for 2-3 clicks for my blog so its too low
That's great earning, what kind of blog do you have? i get 10 -12 clicks in a day and end up earning 0.25$ on an average.
hmm my impression is 3894 and click is 83 my earning is $7.94. please help me to improve my impression and clicks
Definitely sounds like click fraud. Report it to google fast. It seems they have just ignored the invalid clicks which they have been known to do.
I don't think it's a click fraud, he might be driving traffic through some kind of source, one might advertising. It happens some time, once i got 120 clicks and ended up earning just 5 dollars. I had driven traffic through advertisements.
