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.

What subject was the page you were doing this on and showing us the ads that the page was displaying. How about doing a few different pages that have different subjects to see if there are any differences.

Thanks for the review, but given you drew significant attention to the fact that Yahoo now has these ads, I believe there was a skew for users to click on Yahoo ads out of curiosity. While the data is interesting, I doubt the sound validity of the research method.

The ads were run only on this site, after the spike due to the "YPN curiosity" clicks. But I agree, we should rerun these test on dozens, if not hundreds of sites, to make it scientific.

If yahoo approves a couple blackhats we can do a massive test. Hundreds of sites? Make that thousands. I think I know a couple that got accepted but haven't heard anything about YPN from them yet. I applied with a couple sites but I haven't heard of them yet. I guess we'll have to wait until the beta is over.

Saw this Google ad on your homepage today. At first I assumed it was a YPN ad because of the no-relevance factor, but it was Google AdSense. I don't know, maybe its targeted to Nacho. Date Sexy Hispanic Si... Meet Hundreds of Thousands of Singles from Other Races, Cultures. www.InterracialMatch.com
