Something very disconcerting has been taking place within my Adwords account. When I raise my bid for keywords that are labeled as being to low of a bid to land on the first page, I, all too often, see my Quality Score fall a number. Why would this be? At other times, bidding higher raises my Quality Score. This makes absolutely no sense to me, and I would love to hear whether anyone else has come across this issue, and, if so, how they dealt with it. Thanks!
