Google AdWords has begun to roll out the quality score column in advertiser accounts in AdWords last week. Now, Google has announced that the new quality score algorithm has been pushed to the Google servers. In the next few days, these changes will be complete and sponsored ads in the Google results will change - how much they will change is still currently unknown.
It is now important for you to track your quality score, so if you do not see it available yet within your AdWords control panel, keep checking back. You will need to customize your columns in order to view the quality score status.
You will see three indicators in your quality score column: Great; OK; or Poor. This will allow you to see how your ads are being impacted by quality score and give you an idea of whether you should improve them or not.
Google also has more details on the changes in their Inside AdWords blog.
Postscript Barry: Just to be clear, last week, Google released the quality score column to all advertisers in anticipation of the launch of a new quality score algorithm that will affect advertisers minimum bids and rankings in the sponsored search results.
