Today I checked my acount and found my site got 66.67% CTR I think it is too high and the problem is the site is still new and haven't many vistors yet what should I do?
enjoy the earnings. I've got sites that achieve that rate regularly. As long as you didn't do anything wrong you should be fine.
As was said before, as long as you're not doing any thing wrong, you've got nothing to worry about. Is it the site in your signature? If so, I'd imagine people are clicking that first image ad or something.
If you don't have a large number of visitors and still have a CTR of 66% I wouldn't worry about a thing.
If maks is talking about the image ad at the top of the home page, I'd have to agree - it barely looks like an image ad and they probably think they're going to one of your games, or they're just that intrigued by that ad; it's an awesome image ad, you got lucky. To be sure, run a separate channel for you home page and see if that's where the higher CTR is coming from. If you're not doing anything wrong, you've nothing to worry about; along those same lines - if you're doing nothing wrong it won't hurt to ask Google, but I don't think there's a need.
Don't remove it! It's just an ad that REALLY works well with your site. I visited your site and I thought that was just a link to your game as well! And I'm normally completely ad blind!!! Shame you don't have more traffic to make the full advantage of it while that advertiser is using that ad...
I didn't even notice it the first time. I went back and then saw the small google text at the bottom of the image. I wouldn't remove it either. The ad blends very well for your site! I don't see any TOS issues.
