I wonder if anyone else gets good traffic from Yahoo or MSN/Live for a site that uses Adsense as its main advertising? In a way it makes sense that Yahoo and MSN wouldn't want to send a lot of business towards Google. In my experience, FWIW, MSN referrers always gave me the best CTR.
i get decent traffic from Yahoo.. but since nobody uses MSN/Live, i dont get much traffic from it. I would like to think that Yahoo & MSN are more concerned about creating a quality search-engine that gives relevant results to it's users than they are about not sending traffic/potential money to Google.
I get a decent amount of traffic via Yahoo on many of my pages, for some reason I tend to rank better there than I do on Google for almost all keywords/web sites.
Having google ads on your site will have little to no bearing on your yahoo/msn standings... if that's what you are asking.
I have a site that had great rankings and traffic from yahoo & msn and very little from google. It seems that eversince I placed adsense on my home page that rankings and traffic from google shot way up better than they ever were with yahoo/msn. I had several 1st place listings in yahoo & msn now its barely even listed in them. I also changed title tags around the same time. Its probably just a coincedense but I have often wondered the same thing.
