We're pleased to let you know that the improvements to Ads Quality that we announced last week have recently launched. As we explained last week, these improvements better evaluate the precise quality of your ads and improve the way we determine which ads show in the yellow region above the search results.

We also wanted to emphasize that AdWords has always accounted for the influence of ad position on CTR and removed it from the Quality Score. This specific improvement updates this system to make it fresher and more accurate.

Again, while we don't believe that any immediate changes are needed on your part, we encourage you as always to watch your key metrics and to make adjustments as appropriate.
