When we pulled Google results pages for 120 category searches across our four store types, from Denver, Chicago and Dallas, 98 of them showed at least one grid of free product listings. These are product cards with a photo, a price and a store name that Google shows without anyone paying for the spot.
And most of those cards carried stars. Of the 1,913 different product cards we counted, 1,675 showed a star rating with a review count. That's 88%.
Free listings are the part of Google a store can win without an ad budget, and reviews decide how a store's cards look once it's there. This chapter covers who fills those grids, what the cards show, the three different ratings Google uses for stores, why the stars on your ads might not match the stars on a review site, and the store badge that depends on more than reviews. The examples come from the stores in this guide. Your category will fill differently. The rules are the same.
Free Product Grids Showed on 98 of 120 Category Searches. A Store With a Clean Feed Gets In Without Paying.
The grids showed up across every category we checked, though not equally:
- Cookware: 29 of 30 pages
- E-bikes: 27 of 30
- Coffee: 21 of 30
- Fly fishing: 21 of 30
Pages with a grid carried about 19 or 20 different products on average. Google labeled them "Popular products," "More products," "In stores nearby" and "Deals on" a category, among others.
Big retailers filled most of the cards. Walmart appeared on 57 of the 120 pages, Target on 51, Home Depot on 29 and DICK'S Sporting Goods on 27. One surprise: Amazon was the merchant on none of the 1,913 cards. It showed up in the regular results instead. Smaller stores still won cards, including several e-bike brand stores that appeared alongside the big names.
Getting in costs nothing beyond a clean feed. Google says free listings "may show in different places on Google, like Search, Images, Lens, YouTube, Gemini, the Shopping tab, and the products module on Business Profile," and that "in most cases, the Free listings feature is turned on by default." Merchant Center also needs shipping settings for the United States, or shipping costs in the feed. Everything from Chapter 14 applies: accurate prices, stock, product IDs and brand.
Stars Showed on 88% of the Free Product Cards We Counted. A Card With No Stars Is the Odd One Out.
Here's what the free product cards carried, across all 1,913 we counted:
- A star rating and review count: 88%
- Free delivery: 54%
- A crossed-out price: 36%
- A "% OFF" badge: 32%
When nearly nine cards in ten show stars, the card without them is the one a shopper notices for the wrong reason. And Google gives shoppers ways to filter on ratings directly. Its "Refine results" bar appeared on 73 of the 120 pages and showed a "4 and up" rating filter on 42 of them. A product with no rating, or a low one, can drop out of the view entirely once a shopper taps it.
The stars also reach past the grid. On 82 of the 120 pages, ordinary search results for stores carried a store rating line with stars, price range, delivery and returns. A store's ratings follow it around the results page.
Your Shopping Ads Get No Product Stars Until Your Products Have at Least 50 Reviews Between Them.
The stars on a product card are product ratings: reviews of that product. Google's help says to join its Product Ratings program, "you need at least 50 reviews across all your products," and there may be a delay of up to two weeks before they show.
Two details trip stores up:
- Matching. Google uses several identifiers to tie a review to a product, and it names the GTIN, the barcode number, as the most important. Chapter 14 found the GTIN missing from the product markup at several of our stores. If the feed lacks it too, reviews may not attach to the right product.
- Setup and upkeep. When a store first connects a review source, Google says reviews "typically go live 2 to 4 weeks after a successful review." After that, Google says your product review data source "must be uploaded at least once a month."
There's a shortcut worth knowing. Google says "aggregate product reviews appear on free listings regardless of participation in the Product Ratings program." If you use a review app, check whether it sends review data to Google and whether that connection is turned on.
Store Ratings on Ads Need About 100 Reviews From the Last 24 Months and an Average of at Least 3.5 Stars.
Store ratings are different. They rate the store, not a product: delivery, service, the buying experience. They can appear on text ads and Shopping ads like the "Rating for madeincookware.com" line in the ads we pulled, and Google's rules are specific:
- A store "generally needs to collect at least 100 eligible, unique reviews," though Google says the exact number can vary.
- For paid text and Shopping ads, the store "must maintain an average composite score of at least 3.5 out of 5 stars."
- Google "evaluates reviews gathered within a rolling 24-month window."
- Ratings are calculated separately for each country.
Google draws those reviews from several places. One is Google Customer Reviews, which Google describes as "a free program that collects post-fulfillment reviews": after an order arrives, Google asks the buyer to rate the store. Others are third-party review aggregators. A store that wants store ratings on its ads has a direct way to get there: turn on Google Customer Reviews and keep asking.
Asking well is mostly about timing and habit. Send the request after delivery, when the buyer has the product in hand; Google Customer Reviews asks for the buyer's permission at checkout and sends its survey after the order arrives. Ask every buyer, not only the ones who emailed to say thanks; a review program that only reaches happy customers looks like one. And answer the bad reviews in public. Chapter 8 found that most of Made In's recent four- and five-star reviews were about fast service or warranty replacements.
One Cookware Brand Showed 4.9 Stars on Its Google Ads and 3.6 on Trustpilot. Google Counts More Than One Review Source.
In our pulls of cookware ads, the store rating line appeared on ads from all 10 cookware stores we checked. The numbers didn't always match what shoppers find elsewhere:
- Made In: 4.9 stars from up to 20,630 ratings on its Google ads; 3.6 from 217 reviews on Trustpilot.
- Misen: 4.4 on its ads; 4.3 on Trustpilot.
- Caraway: 4.9 on its ads; 4.8 on Trustpilot.
The gap doesn't by itself mean anything is wrong. Google pulls store ratings from several sources, so one site's 217 reviews won't necessarily match a rating built on 20,630. But a shopper who checks Trustpilot after seeing 4.9 on an ad sees a different picture, and Chapter 8 showed cookware buyers on Reddit talking about ads and marketing before they buy.
Coffee shows the other side. Volcanica's ads showed 4.8 stars from about 4,500 ratings, close to its 4.8 on Trustpilot from 8,734 reviews. Onyx Coffee Lab had one ad with a store rating, 4.1 from 10 ratings, and its Trustpilot profile was unclaimed, with one review. Yet Onyx was the most-praised roaster in the Reddit threads we read. In this sample, review counts seemed to track whether a store asked for reviews, not how good its coffee was.
The lesson for a store isn't to chase one site's score. It's to ask every buyer, steadily, through the channels Google counts, and to watch the review sites shoppers actually check.
Google's Top Quality Store Badge Scores Shipping, Returns, Photos and Site Speed, Not Just Reviews.
Chapter 12 showed Made In's store panel on a search for its name, with a "Top Quality Store" badge. That badge is available in the U.S., and Google says that to earn it, "you must rank 'Exceptional' in your overall quality score."
That score covers more than reviews. Google lists:
- Delivery time and cost
- Return window and cost
- Image resolution, with images "more than 1048 pixels"
- Images per item
- Site speed on desktop and mobile
- Store rating, Google's own metric
A few rules matter for stores changing their policies. Google says "it can take up to 30 days for changes to policies (such as returns) to reflect," and that return policies marked as no returns or defective only "are automatically filtered out." The score is calculated for the whole domain, and offer-level data in the feed overrides account-level settings.
Merchant Center has a Store Quality scorecard that rates each of those areas from Low to Exceptional, including Google's own store rating metric. Start with the area rated lowest.
Most of that is in the store's hands. Faster shipping, a clear return window, more and sharper product photos and a faster site all count toward the badge, and toward the store a shopper actually wants to buy from.
Next: One Store Crossed Out a "Regular" Price on 78% of Its Coffee Options. Federal Rules Say It Has to Be Real.
Crossed-out prices showed on more than a third of the free product cards we counted. Chapter 16 covers sale prices and Merchant Center promotions, and the federal rules a "regular" price has to meet.
Earlier chapters cover Merchant Center and the product feed and AI Max for Shopping. Every chapter is on the guide's home page.
When we take on a store through Google Ads management, we check its product ratings, store ratings and review program alongside the feed. Doing it yourself? Search for your best seller on Google and look at whether your product card shows stars.
