Google AdWords announced introducing several improvements to Quality Score giving advertisers more visibility in the scores.
New Status column has been added for Quality Score
Google has added three new optional columns to the keyword tabs for “Exp CTR”, “Ad Relevance” and “Landing Page Exper”. Adding these columns will give you a comprehensive snapshot of the keywords’ current scores. This means no more hovering over the keyword status bubble.
Historical Data for Keyword Quality
Advertisers can now view historical quality score, and its components, for all their keywords to get an understanding on how they have changed over time. There are four new columns to show this data: “Qual. Score (hist.)”, “Landing Page exper. (hist.), “Ad Relevance (hist.)”, and “Exp. CTR (hist.).”
These columns reflect the last known score for the date range you select. Historical data will not be available for the dates prior to January 22, 2016. You can apply Day segment, to see daily values reflecting what your scores were at the end of each day.
