Google is now placing AI-written summaries of online reviews inside its Search ads, and advertisers cannot edit what those summaries say. The feature, called review summaries, is set out on a Google Ads Help page and is available in the US, the UK, Australia and India, in English.
The page carries no publish date. It reads as documentation for something already running rather than as a launch announcement.
What Google’s Help Page Says
Google describes review summaries as “AI-powered summaries of online reviews that appear directly as part of your Search ads.” Its AI gathers reviews “from across the web” and turns them into short commentary that sits within the ad itself, not beside it.
The summaries are positive only. Google says they highlight benefits drawn from customer reviews, and that its AI uses “grounding standards to ensure content reflects real feedback.” The page does not name the review sites or sources the AI draws on.
Eligibility is broad. Review summaries can appear in Search campaigns, in every ad position on Google.com and on all supported devices. Every advertiser vertical qualifies except sensitive categories, with pharmaceuticals given as the example.
Google also decides when they show. According to the page, a summary appears only when Google predicts it will improve the ad’s performance.
From Small Experiment to Help Centre Entry
In early July, advertisers spotted AI-written summaries beneath some Google Search ads. A Google spokesperson told Search Engine Land at the time that it was “a small experiment to see if adding AI-generated context to Search ads helps people make more informed decisions.” Later that month, similar generated text appeared in Shopping and Product ads.
Google has not said that the July test became review summaries. The July summaries carried a general disclaimer that Google AI responses “can make mistakes,” while the new page presents the text as a digest of customer reviews. Both point the same way, though. Google is writing part of the paid ad unit itself.
Review summaries also extend a format Google already runs. Seller ratings, one of its account-level automated assets, show a combination of information and reviews next to ads. Review summaries turn that signal from a rating into AI-written sentences inside the ad.
What the Page Leaves Out
The central line sits in the page’s Key considerations section: “Because review summaries represent user feedback, advertisers cannot directly edit or customize the generated text.”
The page does not say whether advertisers can switch review summaries off. Its only related link points to Google’s guide to account-level automated assets, which explains how to turn those assets off one type at a time. That guide lists seller ratings, dynamic sitelinks, dynamic callouts and site visits among its types, but it does not list review summaries.
The page is also silent on how the summaries are labelled for searchers, and on whether advertisers can see in their reporting when one has shown.
Who Answers for the Text
Meta has already given its answer to a similar question. Its updated Commercial Terms, which take effect on 20 November, make advertisers “solely responsible” for content its AI features create or change. Meta also lets advertisers turn off each Advantage+ creative enhancement separately.
Google
MetaGoogle’s page does not address responsibility. What it does settle is authorship. The summary is Google’s text, built from reviews Google gathers, and it appears as part of an ad the advertiser pays for.
For advertisers in the four markets, that means a searcher can now read words about their business inside their own ad that they did not write, cannot change and have not been told how to remove.
Recap
What are Google’s review summaries in Search ads?
Review summaries are AI-written summaries of online reviews that Google shows as part of Search ads. They are available for Search campaigns in the US, the UK, Australia and India, in English, across every ad position on Google.com and all supported devices.
How do review summaries work?
Google’s AI gathers reviews from across the web and turns them into short, positive-only commentary about the business. Google shows a summary only when it predicts the summary will improve the ad’s performance, and sensitive categories such as pharmaceuticals are excluded.
What changes for advertisers?
Part of the ad is now written by Google rather than the advertiser. Google says advertisers cannot edit or customise the generated text, and its help page does not say whether they can switch the feature off.
