Google AdWords blog announced it will be launching the changes it told us about last month in the next few days.
Still no mention on turning on old accounts when they stop the inactive status, but they have given more details on how the Quality Score is measured including all of the CTRs in your account. This may force people to be a lot tighter with the keywords they add to their accounts so they do not have to pay higher rates for their established terms.
The front page bid estimates that will be replacing minimum bids also have some interesting new details:
For queries without many advertisers competing for placement, the first page bid estimate should be relatively close to your existing minimum bid. However, queries with a high level of advertiser competition may have significantly higher first page bid estimates, because you’ll likely need to bid above the old minimum bid to rank higher than your competition and show on the first page. Remember that you can bid less than your first page bid estimate and still show on subsequent pages — as long as your keyword is relevant to our users.
Advertisers familiar with the competitive landscape for their keywords may indeed notice that the first page bid estimates provided are in line with the CPCs that they had been bidding to appear on the first page prior to the release of these Quality Score improvements, although this is not a given.
