At my forum, the CTR is .40 or .30 lol Congratz. I have no idea about what google does? but I have heard high CTR can be trouble. Make some page views yourself or add more pages.
I got 100 % CTR, a few days ago. 4 impressions 4 clicks It was only worth $1.89 though. My site gets only 15 to 20 uniques per day so I was happy!
