Google announced three major improvements to the AdWords marketplace. First, Quality Score will now be more accurate because it will be calculated at the time of each search query. Second, Keywords will no longer be marked 'inactive for search', and last, Google has removed the “minimum bid” metric and replaced it with “first page bid.”
Google says they'll release these Quality Score changes to a very small segment of advertisers within the next day or two. Google will be watching how this impacts those advertisers and will then decide when to launch this on a broader scale.
