You haven't a banner the placement of ads is good But i think you should use 3 columns theme, It look so cool
The blog is missing a header, you should add a header with some graphics to make the blog look more attractive.
Ads placement looks fine but it seems that the ad units doesn't look blend in. Try to search around for a new template. The current one sure looks odd to me with the missing header.
i used 3 column in the the past and it didn't like me i think there is many things in the blog so i changed it
i'm agree with you but i don't know how to make a header with graphics if you don't mind please tell me how
please review the position of my ads as since i put them in this position i receive every day click from it http://egboursa.blogspot.com
