Google documented AI review summaries in Search ads for the US, UK, Australia and India

A new 'About Review summaries' help page documents AI-generated summaries of online reviews that appear as part of Search ads. Google aggregates reviews from across the web, shows only positive insights, and displays a summary only when it predicts the summary will improve ad performance.

The page sets out the conditions: Search campaigns only, all positions on Google.com, English in the US, Australia, UK and India, all supported devices, and all advertiser verticals except sensitive categories such as pharmaceuticals. Google says advertisers cannot directly edit or customize the generated text because it reflects user feedback, and the page does not say whether advertisers can opt out.
