Would love some feedback on my adsense placement

Hi - first time poster, long time reader

I would love some opinions/feedback on my adsense setup:

Example #1
http://www.htmlcenter.com/tutorials/tutorials.cfm/61/CSS/
-- sometimes it will appear in the top leaderboard slot (rotates)
-- left menu under become a sponsor
-- middle 336 box
-- right 200 slot btw blog and forum

Example #2
http://forums.htmlcenter.com/t13.html
-- sometimes it will appear in the top leaderboard slot (rotates)
-- always below 1st post
-- always on right 160 skyscraper under feeds

Any help is greatly appreciated!

 

i have only checked forums.htmlcenter.com .

i think you must convert your ads to square size

 

thanks, do you mean below the first post in a thread?

 

any other suggestions?

Thanks!
