I presume that Overture and Google have pretty much the same amount, but how do Espotting, Webfinder and Mirago compare? I would think that the number of advertisers dictates the bidding level on the top phrases (not just the depth of advertisers on a phrase), as well as the spread of phrases covered.
It would be useful for potential affiliates to be able to make a comparison in this way.
Mirago is pretty good for volume and they also have some interesting (if difficult to implement) features, including dayparting and publisher exclusion.
I'd certainly recommend they are worth a trial, as would Webfinder, albeit that Webfinder has a trickle of traffic at the moment, but growing steadily, local search will be where they come into their own.
For new advertisers there's never been a better time to trial PPC with plenty of freebie offers.
