"Ads above the fold" may be a slight red herring for a description.
I agree with that. I got a call from Adsense about a year ago. She wanted me to change some of our text ads to image ads. She said it was great all were above the fold.
Again, Adsense may be separate from Google search, so they have different interests.
Also, AOL (advertising . com) pays us more for having their ads above the fold.
It is a tough choice, give up rank to make more in advertising - but rank will cost you too.
