We have recently wrote about Yahoo Charging More & Giving Less. But it seems like a new wave of spikes in minimum bids have been surging through Yahoo Search Marketing campaigns.

A WebmasterWorld thread has a few advertisers complaining that Yahoo has increased their minimum bids again. Some advertisers are so tired of the increases in costs that they are dropping all or half of their budgets with Yahoo and moving it elsewhere.

I also received notification that my bids were going up, but then I received an email that they went back down. I think this might have been a bug related to email, but again, I am not sure.
