Using the status hover for a keyword in the Keywords tab, you’ll see the traditional 1-10 numeric score and new ratings for each main factor in Quality Score. The new ratings have a relative scale so you’ll understand whether your performance expected clickthrough rate, ad relevance, and landing page experience is average, above average, or below average compared to other advertisers.
We’ve heard from advertisers that having more insight on Quality Score can help you better focus efforts to improve performance. Improving ads quality is great for users, too.
One final note: This launch gives you information you can use to improve your Quality Score, but it doesn’t change how Quality Score or ad rank are calculated.
