On buying searches, 84% of AI Overviews cite a Google product page. The opinions come from YouTube
A new Babel42 study splits Google's shopping AI Overviews into two jobs: Google supplies the product link, and video, forums and reviewers supply the opinion. Big retailers rank on page one but get cited far less. Here is the data, read for packaged goods brands.
Most AI Overview studies answer one question: how often does the summary appear? A study published on November 1, 2026 by Babel42 answers a more useful one for anyone who sells products. When Google writes a shopping summary, whose pages does it point to, and for what?
The answer splits cleanly in two. On buying searches, Google points to its own product pages for the product link, and to video, forums and independent reviewers for the opinion. The big retailers that dominate page one of the regular results are cited far less than they rank. For a CPG brand, that turns AI Overviews from one problem into two: get your product into Google's listings, and get your product into the reviews and videos Google quotes.
How the study worked
Babel42 picked 660 US English searches: 600 generic searches, 100 in each of six industries chosen by a fixed rule from the highest-volume US searches, plus 60 "[brand] reviews" searches. Online shopping was one of the six. On day one it recorded the organic top 10 and both of Google's AI answers. The 601 searches that showed an AI Overview were then rerun daily for 15 days, between September 26 and October 12, 2026.
A site counts once per answer, however many of its pages are cited. "Google's own pages" means any google.com link an AI Overview cites, which in shopping are product pages.
Two caveats before the numbers. These are high-volume commercial searches, not a random sample of what people type. And the shopping set leans toward electronics and general merchandise ("best cheap gaming headphones" is the study's example), so the opinion sources will look different in, say, sunscreen or protein bars. The structure of the answer is what we would expect to carry over.
Google supplies the product link
Across 1,331 online shopping AI Overviews that cited at least one site, 68.0% cited a Google product page. The share depends on intent.

| How-to and information searches | 6.7% |
Source: Babel42, November 1, 2026. Base: 1,331 online shopping AI Overviews citing at least one site. Buying searches contain words such as best, top, cheap, vs, review, price or which, and not how.
A buying search, in the study's definition, contains words like best, top, rated, cheap, affordable, vs, review, price or which, and not "how." Those are exactly the searches a CPG brand cares about most: "best natural deodorant," "cheapest dishwasher pods," "protein bar vs granola bar."
There is a wrinkle that matters. Google rarely listed its own page first. It was the first cited source only 2.0% of the time and was typically sixth. So the Google product link is almost always present on a buying search, but other sites lead the list of sources. For a brand, the two questions are separate: is your product inside that Google link, and which sites fill the places above it?
Shopping is where Google cites itself most
No other industry comes close.
| Industry | AI Overviews citing Google's own pages | AI Overviews in the base |
|---|---|---|
| Online shopping | 68.0% | 1,331 |
| Travel | 25.8% | 1,259 |
| B2B software | 8.0% | 1,514 |
| Local services | 4.3% | 1,127 |
| Health | 2.6% | 1,545 |
| Finance | 0.7% | 1,519 |

This lines up with what Findrix found in Google's AI Mode. In a study of 55,198 answers, AI Mode linked only to Google's own pages in 46.5% of US product answers, and 57% of links in its product answers led to Google Shopping pages. Two studies, two different Google surfaces, the same habit. When Google has its own listing for a product, it uses it.
Big retailers rank, but get cited less
The finding we did not expect concerns retailers. On the 26 September results, big retailers and brand stores held 18.1% of page-one results on the shopping searches. They were only 6.6% of the sites AI Overviews cited.
| Measure | Big retailers and brand stores | Any other page-one site |
|---|---|---|
| Share of page-one results | 18.1% | |
| Share of sites cited by shopping AI Overviews | 6.6% | |
| Chance of being cited when on page one | 22.4% | 32.7% |
Source: Babel42. "Big retailers and brand stores" is a fixed list including Amazon, Walmart, Best Buy, Target, Nike and Apple.
Babel42's guess, which it labels a guess, is that the two findings are linked. Google already supplies the product link through its own pages, so a retailer's product page offers the same kind of link and the summary has less need for it. That is plausible. It also means a ranking on page one, whether on your own site or on a retailer's, is a weaker route into the AI answer than it looks.
The opinions come from people who do not sell the product
If Google supplies the link, someone else supplies the reason to buy. In shopping AI Overviews, that someone is mostly video and discussion.

| Site | Share of AI Overviews |
|---|---|
| YouTube | 68.2% |
| Google's own pages | 68% |

| RTINGS | 23.1% |
| New York Times | 18.5% |
Source: Babel42, November 1, 2026. 1,331 online shopping AI Overviews citing at least one site, Sept 26 and Sept 28 to Oct 12, 2026.
YouTube was cited in 68.2% of shopping AI Overviews, a hair more often than Google's own pages. Reddit came next at 26.3%, then two review publications. None of them sells anything. Each does a different job: YouTube carries demonstrations and reviews, Reddit carries discussion between buyers, and RTINGS and the New York Times carry tested comparisons.
For packaged goods, the review publications in a category will differ. A snack brand is unlikely to be reviewed by RTINGS, but there are equivalent testers and roundup writers in food, beauty, cleaning and baby care. The structure holds: an AI Overview on a buying search pairs a Google product link with opinions from sources that test, show or discuss the product.
How-to searches are a second way in
How-to shopping searches rarely cite Google product pages. Only 6.7% did. Babel42's reading is that guides and how-to videos fill that space. For a CPG brand with good usage content, that is an opening. "How much detergent for a front loader," "how to store cold brew concentrate" and "how to use a retinol with vitamin C" are searches where the product link is not taken by Google by default, and a clear, specific answer from the maker has a chance.
Coverage is rising on both kinds of search. AccuRanker reported that AI Overviews on tracked commercial desktop searches went from 26% on September 1 to 51% on September 30, 2026. More summaries means more of these two-part answers.
What this means for a CPG brand
Your Google product listing is the product link. If 83.6% of buying-search summaries cite a Google product page, a product that is missing from Google's listings is missing from the link most of those answers carry. Google's free listings help page says new Merchant Center accounts are opted in by default and lists the required attributes: id, title, link, image link, price, description, availability, brand and GTIN for products that have one. It also says Google may show products crawled from your store even without Merchant Center, but you control the details only through your own data. Tip 16 covers how Merchant Center feeds AI shopping results.
Retailer offers count too. The Google product page aggregates offers from every merchant that sells the item. If your brand sells mostly through Target, Walmart and Amazon, their feeds put your product into that page. Check that the title, size and image on those offers describe the same product as yours, because Google uses identifiers such as GTIN to match product data to searches.
Reviews and video are the opinion layer. YouTube at 68.2% is the number to sit with. A brand with no third-party videos showing the product in use is giving the summary nothing to quote. That does not mean paying creators for scripted spots. It means sending product to the reviewers and testers in your category and making it easy to film. Tip 10 and tip 26 cover reviews and transcripts.
Do not chase page one alone. A retailer ranking on page one had a 22.4% chance of being cited. Ranking is still worth having, but in shopping it is not the main route into the summary.
How to check your own categories
Pick ten buying searches and five how-to searches for your top product. Run each in Google on a US connection, open the AI Overview's sources, and write down three things: whether a Google product page is cited, which opinion sources are cited, and whether your product appears in either. Repeat weekly for a month, since the study found sources change from day to day. We use the same approach for assistants; XENA Intelligence, for one, asks assistants shopper-style questions and scores how each product shows up in SearchPanel, and a spreadsheet does the same job for a short list.
A month of that log should tell you which job is weaker for your brand: the product link or the opinion. Our guess is that most CPG teams have spent years on the first, through feeds and retail media, and much less on the second.
Questions
Do Google's AI Overviews link to Google Shopping product pages?
Often, on shopping searches. In Babel42's study of US searches from September 26 to October 12, 2026, 68.0% of online shopping AI Overviews cited a Google product page, and 83.6% of those on buying searches did.
Which sites do AI Overviews cite for product opinions?
In the same study, YouTube was cited in 68.2% of shopping AI Overviews, Reddit in 26.3%, RTINGS in 23.1% and the New York Times in 18.5%. None of them sells the product.
How does a brand get into the Google product link that AI Overviews cite?
That link comes from Google's product listings, which draw on Merchant Center data and on product details crawled from your store. Keeping free listings on and product data complete is the route in, though Google says showing is never guaranteed.
Do big retailers get cited in shopping AI Overviews?
Less than they rank. Big retailers and brand stores held 18.1% of page-one results on Babel42's shopping searches but 6.6% of cited sites. A retailer on page one was cited 22.4% of the time, against 32.7% for other page-one sites.
