What theme will increase my CTR?

I got my autoblog up and running for about a week now, and really miss a little ctr.
The first day it was running its looked to become a great success. It got a little above 100 visits, and made a little above 3$.

It still got the 100 visits, but no one click the ads.
This is the first blog i have made, so i need a little advice.
What WP Theme would suit my blog the best? Should i tweak anything else than the theme?

The Niche is eBook Readers.

Theme does not much help to increase CTR while ads position does matter. I think you should use two sidebar, narrow and fixed width theme. It will help highlight to ads and such CTR may be increase.
