that's pretty darn good.. But posting your CTR will make Mr.Google angry because it violates the TOS..
Good CTR for a week old site...But don't reveal the CTR in open forum although you've stated one of my site.
How much traffic are you getting. If you are only getting 20 or so, it can be very easy to get high CTR as you would only need 3 or 4 clicks to have that figure.
That is very good and you know it Most sites get less than 1% and a good site in my terms will get around 3%.
