I did some tests recently and also found less ads performed better.

My theory is that when there are text ads - the ads that are higher on the page pay more (I believe ads are displayed in order of the advertisers max CPC right?). When there are more ads on the page, there are more low paying ads - so even though u might get more clicks when more ads are on the page, they are often lower paying.

When I have less ads on a page, my average CPM is much higher, but my CTR is lower - overall I'm making more.

I mean no offense here ASA - but I hear your message quite often on adsense blogs about placing more ads but I constantly see in forums people saying less ads is performing better. I wonder if it is just google policy to promote people to place more ads ;) I can imagine that would be a good thing to get more advertiser impressions.
