I think my site has good ad placement but im new to adsense and need the opinion of experts like YOU!. Site: http://tinyurl.com/2n6zmz Please post all comments / suggestions / questions here. ~Thanks!
create something like the "welcome to prankmailer" image, place it underneath the intro, label it Adverts also, and pop in a 728. It'll be in the middle of the page.or 2 big AdSense 336 squares. Depends how aggressive you want your AdSense ads to be.
I would suggest put a rectangle image ads below the email box.. That is the high potential place too.
