Here is the thread I was talking about - Result of adding a second AdSense unit.
Quote:
Here's what happens when you add a second Google ad, Clickthrough rates crash. I went from about .5 to .2, and my Effective CPM has also been cut more than half. Thats because each ad counts as one page impression and of course the bottom ads will be clicked way less than the top ads. Each page view generates two page impressions. If you show three ads per page it'll crash even more!
If Google terminates affiliates because of CTR or CPM rates, there might be a lot of us that end up geting that dreadful E-mail.
Before this change I averaged 15,000 page impressions a day, and with nine hours left today, I've got 39,056 'Page impressions', er ad impressions. By the end of the day it'll probably be more like 70,000-80,000 with about 30,000 of that being from adding the ads to my vBulletin boards. Still a huge increase from 15,000!
I think they should change 'Page impressions' to 'Ad impressions'. Earnings wise it looks like it's staying about the same. I'll need a few extra days to see how much of the earnings come from the channels for the second ads, and message boards.
This also increases the number of PSA ads, or your own ads, BIG time. Before this I was geting my own ads to show up about 1,000 times per day, and today it looks to be around 10,000 ad spots showing my own ads. I don't think those numbers are included in the page impression number, so it might get close to 80-90,000 total impressions counting my own text ads!!!
