you can buy CTR wordpress theme that's designed to gain more adsense click

 

Try to place your ad under the article title

 

Place your ads;

Below Header + Below Post title + Pagination(Page Count) Area

 

Place ads 336x280 floating in your post, 728x90 under top menu, 160x600 in sidebar.... Set color of ads title same like color of title post, use same font type and size.. Good luck..
