Forum Moderators: werty
I'm pretty sure they're exclusive to themselves at this point. Haven't seen any Yahoo/Overture ads showing at MSN last few days.
"Do you think they have enough volume to do so at this point?"
I think they have enough. Right now they don't have near the same amount of advertisers as Google does, which makes it for me at least, cheaper. Less competition for the campaigns and keywords I'm targetting, so some good deals.
On average each day I'm getting 15-30k impressions each on overture and MSN (2-3x as many kws on MSN though) with a 2% CTR on overture and 4% on MSN. They are both converting about 2%.
With adwords I'm getting 100k impressions at 4% CTR, same or a bit better conversion rate.
YMMV
In the good old days (a couple of months ago) I was getting a 500% ROI with MSN, but with lower traffic.
