Microsoft Advertising Introduces Asset Performance Ratings for Responsive Search Ads
https://about.ads.microsoft.comAsset performance ratings help you understand which of your headlines and descriptions are working well, and which are not. They provide a new level of insight beyond raw impression counts, to help inform your decision making throughout the lifetime of your RSA. When a new RSA is created, or an asset is added or edited in an existing RSA, Microsoft’s artificial intelligence and machine learning algorithms automatically set out to determine how well assets are performing whenever they’re being shown.
When an asset’s performance is currently being evaluated, its rating will show as Learning. Once an assets performance rating has been determined, it will show as Low, Good, Best, or Unrated.
