What do you think about my placement?

What do you guys think about ad placement on my new site-
http://www.rankalert.net

Although it is a webmaster site but it is getting a decent CTR. I think thats because of nature of ads.

Any suggestion to improve/better placement.

I dont want to blend the ads such as they hide between content, that would trick people to click on the ads.

 

Nice ads blending with site colors,but i will put one ad in the middle of page.

 

Thanks for your review

There is a link unit in the middle of the page..
Banner doesnt look good, I tried it.
