Google explains the AI review summaries inside Search ads

Google published a help document on review summaries, the AI summaries of online reviews shown as part of Search ads. Google aggregates reviews from across the web, and the summaries are positive only. They run in Search campaigns in all ad positions on Google.com.
Our take
Reviews on third party sites now write part of your Search ad. Ask happy customers to name the specific result they got, since specific praise gives the summary better material. Search your top keywords to see what Google pulls for your brand, and fix outdated claims on any review profile you control.
