Google has announced new quality score updates. Instead of rehashing their entire post, I’ll outline the 3 new points and link to their entry about it.

* Quality Score will now be more accurate because it will be calculated at the time of each search query
* Keywords will no longer be marked ‘inactive for search’
* ‘First page bid’ will replace ‘minimum bid’ in your account
