That deserves an explanation.
Monday: I get a call from one of my customers, who had bought sponsored links directly to an affiliate website. In the same box on the website, there were also some of our Yahoo ads (you could tell with the tracked URLs) served by Search123.
Quite funny when you think about it: Yahoo had stopped its Content Match offer since March 09 in Europe.
Calling Yahoo to get an explanation, I was told these ads were distributed through their Search Partners network from which you can't opt out. Nice!
One sentence struck me : "We occasionnaly fetch ads in the search feed to distribute them through our Search Partners network, but we do remain a Search Network you can trust".
Trust ? Hmmm, I'm not comfortable with that for now.
Insisting a bit, they told me that :
1. "You can opt out of any Search Partner by excluding it in your account"
2. "We don't give out our Search Partners list"
Very useful !
So I started investigating. There's a whole litterature that has spread online, so here are the most interesting links I could come up with:

So I set up additional Google Analytics profiles for all of my websites with incoming traffic from Yahoo Paid Search, in order to check all referers. The process is quite simple, you just have to set up some filters :
- Include only traffic from source "yahoo"
- Include only traffic from medium "cpc"
- Advanced filter : Append Source field with Referer URL
You can refer to http://www.ga-experts.com/blog/2006/11/how-to-assess-search-content-network-advertising-using-google-analytics/ (screenshots included).
Do Yahoo really fetches ads "occasionnaly" ? Can you really "trust" them for being a "Search Network" ? I don't think so anymore. What I trust are accountable facts and figures, and I urge everyone here to set up profiles to check on that.
