Google has a help page for AI review summaries in Search ads, “About Review summaries” (answer 18760807), and it says advertisers cannot edit the text. The page has no date; PPC News Feed reported it on October 24, crediting Hana Kobzová with finding it. Its only related link leads to the account-level automated assets page, and we opened that page: its list of automated asset types does not include review summaries.
What are Google Ads review summaries?
Google defines review summaries as “AI-powered summaries of online reviews that appear directly as part of your Search ads.” The page says the summaries are “positive only” and appear as short AI-generated commentary, built from reviews “from across the web”. Eligibility is Search campaigns, all positions on Google.com, in English in the US, AU, UK and IN, for all verticals except sensitive categories, “such as pharmaceuticals”.
The same page explains the rule and undercuts it
The reason given for the no-editing rule is in Key considerations: “Because review summaries represent user feedback, advertisers cannot directly edit or customize the generated text.” Further down the same list, the page says that “Review summaries are only positive”, and that they “only show when predicted to benefit your ad performance”.
Read together, the text inside a paid ad is described as user feedback, filtered to the positive, and shown when Google predicts a lift. PPC Land got there first, calling positive-only “a selection rather than a representation of the overall balance of opinion”. It also noted that the page does not say whether a low-rated business can still get a summary, and does not define the performance prediction.
The page it links does not list them
The only related link on the page is “About account-level automated assets”. Its “Types of account level automated assets” section lists nine: dynamic sitelinks, dynamic structured snippets, automated location assets, seller ratings, dynamic callouts, dynamic business information, dynamic image assets, automated promotions and site visits. Review summaries is not among them. The phrase appears only in the Help Center’s side navigation, as a link back to the page we started from.
The turn-off procedure there (Assets, Associations tab, Account level automated assets, Advanced settings, then “select which asset to turn off”) names no specific asset, so it cannot show whether review summaries is one of the choices. PPC Land said the link does not establish that the account-level controls apply; the list confirms the gap. We are not saying no control exists. We are saying neither help page, as of October 26, describes one.
Review summaries vs store ratings: what each Google page documents
Store ratings, another review-based ad element (the “seller ratings” entry on the automated-assets page links to this same help page), make a useful yardstick. The table sets the two help pages side by side, using only what each page states.
| Item | Review summaries (18760807) | Store ratings (2375474) |
|---|---|---|
| Sources named | None; “from across the web” | Google Customer Reviews, shopping reviews from review partners and Google Search users, Google-led shopping research; 29 partners listed |
| Threshold | None stated | 3.5 stars or above on text ads; most merchants get a rating after 100 or more eligible reviews collected within 24 months |
| Editing | Generated by Google AI; advertisers cannot directly edit or customize it | “Google doesn’t modify existing ratings”; it calibrates them and filters out untrustworthy reviews |
| Performance figure | None; shown “when it’s predicted to improve ad performance” | “on average drive a 2% improvement in click through rate” on the Search network, footnoted “Google Internal Data” |
| Report | None documented | “Account-level automated assets” report |
| Turn-off steps | None on the page | “follow the steps to turn off store ratings” |
| Markets and campaigns | Search campaigns; US, AU, UK, IN in English | Search Network campaigns; ratings are calculated per country |
What the page leaves out
PPC Land listed most of these gaps on October 25, and the store-ratings page makes them concrete: the review summaries page has no list of sources beyond “across the web”, no minimum review count or rating, no screenshot, and no description of any label on the ad. Sensitive categories are excluded, but only pharmaceuticals is named. It does not say where results are reported, how to switch the feature off, or whether clicks on an ad with a summary are billed any differently from other clicks.
The automated assets page does say there is no cost when assets show with your ads, “but you’re typically charged as usual for clicks on your ad”, though clicks on the seller ratings themselves are free. Whether review summaries follow that rule is not stated on either page. PPC Land also pointed out that the Help Center’s AI box suggests the question “How do I enable AI review summaries for my Search ads?”, which the page does not answer.
A measurement caveat
This part is our analysis, not Google’s. If a summary appears only when Google predicts a performance benefit, then ads carrying one are a pre-selected set of auctions. Comparing their click-through rate or conversions with ads without a summary would compare different auctions, not run a test. With no report documented, an advertiser has no stated way to separate the two sets.
Earlier sightings
- Dec 3, 2025: review excerpts mostly on e-commerce ads, which PPC News Feed said appeared to come from store ratings; spotted by Anthony Higman, as listed by PPC Land.
- Jul 1, 2026: Search Engine Roundtable reported Google testing AI-generated summaries in sponsored results “right below the description”, with the ad disclaimer “Google Al [sic] responses are generated independently and can make mistakes, so double-check responses.” PPC Land notes that this variant summarised the advertiser rather than reviews.
- Aug to Sep 2026: PPC News Feed reported review-focused tests labelled “What people are saying” and, on September 5, “What customers love”, per PPC Land.
- Oct 24, 2026: PPC News Feed reports the help page. PPC Land followed on October 25.
The disclaimer was seen on the July variant; as PPC Land noted, the help page does not say whether it accompanies review summaries now.
Reading the page next to its neighbours
We read one Google Ads help page against another in our piece on the Smart Bidding learning rewrite, and the same habit applies here. Our piece on language targeting leaving Search covers another change in what advertisers can control. For review summaries, neither help page describes a switch.
