When I began with AdSense, I had three ads (728 x 90 leatherboard) on every page.
The problem with this is that you are putting 12 ads on the page. The last few ads are going to be poor performers, meaning the epc will be very low.
When I made my change, I used banner size ads and / or rectangles. At most, there are only 4 ads to click on each page. This sent my earnings per click up quite a bit.
Just a thought.
