I am getting concerned that my click through rate might be too high as daily it is around 13% I hear about people be banned from adsense due to fraudulent clicks and stuff, because their click through rates are high! Is mine high? Should I be worried?
It does seem higher than average, but I wouldn't be too concerned just yet. Be sure to keep an eye on your visitor logs and report anything untoward immediately.
I used to have over 30 percent CTR. It would even go as high as 40 percent, for two years, and I never got a single warning.
one of my site had as much as 35% CTR at one point till traffic slowed down by a lot. that site is 100% content based and ads were blended within the content at the top of the body. so there's nothing wrong about this
