I've never bought this traffic and I was considering it for a few clients. Any success stories? Seems like it would be WIDE open for new advertisers compared to adwords or YSM
My site is hosted by Microsoft and while on their community forum I haven't hear promising things about their "adwords" campaign I would stick with Google when it comes to advertising, at least for now. Microsoft has a lot of stuff still in beta and they are not quite where they need to be.
We've recently started a campaign with microsoft. We'll let you know how it goes in a review at a later date.
I am using adwords and i am happy with it. If you don't have an account already you should open asap.
