There was some buzz yesterday afternoon about an email Yahoo has sent out announcing that it will no longer allow pay-per-click customers to bid on another company's trademarked terms. MarketingVox also posted this announcement this morning.
I will try to confirm this in the next few days, but if true, this is a big step. Competitors bidding on another company's name or other trademarked terms has been a sore point for many advertisers for some time.
Google and Yahoo to-date have allowed competitive bidding on these terms. MSN AdCenter, which is due to launch this Spring sometime, is not allowing these sorts of bids.
I will keep you posted. In the meantime, what do you think about this sort of bidding? Have you been a victim? Do you buy competitor terms? How do you feel about this change?
