Search Engine Watch Forums moderator, abbottsys, posted detailed feedback on Google Ads Being on Yahoo Search. The Search Engine Watch Forums thread has only one post but deserves a lot more participation, in my opinion.
Normally, I would summarize, but I am not feeling so well and abbottsys does a great job, so let me quote him:
1) My ad was subscribed to Google Search and the Google Search Partner Network, but it was not subscribed to the Content Network2) I bid high so I could be sure of seeing the ad. I also shut down all my native Yahoo campaigns. As soon as I shut them down my adwords ad took over on Yahoo.
3) My ad appeared at the top of Google and Yahoo. My ad ranking on Yahoo was slightly better than on Google.
4) Changes to the ad were reflected with equal speed on both Google and Yahoo.
5) I found it *very* convenient that I could manage my Yahoo campaigns from AdWords. I've always been a big fan of the AdWords management interface, which I feel is *far* superior to Panama, AdCenter, or any others out there. In fact, I was surprised how refeshing it was not having to mess with multiple ad management platforms.
6) As regards ad performance (CTR, conversions) I was very happy. Of course, since this was a Yahoo test I have no idea if these clicks were charged or even reported in my AdWords account. But the ad did perform well.
7) I've been doing this PPC stuff since 1998. My overall comment on this particular experience is that it was great. I really liked it from all aspects.
8) If this test leads to a full ad distribution agreement between Yahoo and Google my only additional request would be that my AdWords ads show up on the Yahoo Content Network. Currently ad distribution on this network is a mess, and needs to be upgraded. Yahoo clearly has infrastructure problems with ad delivery on their Content Network. Letting AdWords handle this would be a much needed upgrade!!!!
9) Bottom line. As an advertiser I simply loved this! Two thumbs up!!!!!!!!
In the meantime, the DOJ is investigating the Google/Yahoo ad test. So even though some advertisers might love to see Google provide the search ads for Yahoo, the DOJ might prevent that from happening.
