AdSense Compared to YPN: Advantage YPN

Recently I was able to delivery both YPN & AdSense ads here on 50/50 rotation. In the past I used word of mouth to report on Google AdSense Versus Yahoo! Publisher Network performance. I did promised you to share some results, on a generic level, of the two programs compared side by side. So here we go...

Date Range: 09/09/2005 - 09/19/2005

Network	YPN	AdSense	Advantage
Impressions	Bit More	Bit Less	Slightly YPN
Clicks	Bit More	Bit Less	Slightly YPN
CTR	Equal	Equal	None
CPM	Much Higher	Much Lower	YPN 81% Higher
Earnings	Much Higher	Much Lower	YPN 82% Higher

So the reports seem to match much of what I reported here. Except for the fact that YPN had less click throughs. Let me tell you the ads matched 100% (excluding one saying Ads by Yahoo! and the other saying Ads by Google). I think its ok if I report these numbers in such a generic fashion.
