@robster124 Are you saying that you're using a 728x90 on a mobile page or am I misunderstanding? I can't imagine it would be very effective due to only being able to see part of the ad without scrolling/zooming. I use 234x60's and 200x200x a lot and they do fairly well. The 320x50 doesn't work well with my design (margins and padding push it outside the viewport in most cased but that's just my design).
I won't throw advice at you 'cuz I'm not sure if I even understand your approach but your comments did raise a question or two. For example, are you using responsive design?
