Hello there.

First off before you add any adsense (and you want to make money off it) you MUST have A TON of traffic to your site. Your site looks good by the way. Back on topic....if you don't have a lot of traffic and a good following, adsense won't do well.

If you have a lot of traffic here are some cool things you can do!

-I see that some of your ads look like adsense. The best thing you can do is to blend them into your page so they don't look like an ad, just a helpful links for people to follow.
- on this site How I crossed 100K alexa Rank in Just 81 Days - Niche Bloggers it looks like ads , FYI

-I like to put them into the side bar to as links. Make sure you change the color of the text and such to blend it in again

-I like to do a banner style adsense at the top of my blog post and that works pretty good. also on the bottom.

-Also along the top of your website where your tabs are is another good spot to place adsense.

For example:

Your Tab Your Tab Your tab Your tab Your Tab
Adsense adsense adsense adsense adsense.

This works great to.

All in all people know ads when they see them.
I encourage you to check out other sites and see how they use adsense.

If you are doing the site totally for clicks then the CTR Theme (CTR Theme - The Ultimate AdSense Theme) gives some of the most talked about layouts.... even if you don't want the theme it may be worth looking at the demo's to see where they are putting them
