What will happen to a responsive display ad if, when reviewing ad strength, an advertiser doesn't follow Google Ads' system recommendation to add more assets?

A responsive display ad is an asset-based format, so Google builds the ad from available images, headlines, logos, and descriptions. When more high-quality assets are provided, Google can test a broader set of creative versions and match them more effectively to placements and users. Google’s ad strength guidance specifically recommends adding more and more diverse assets to improve performance. Ignoring that recommendation does not stop delivery, but it does reduce the creative flexibility the system can use during optimization
