About Product Ratings
Product Ratings show star ratings on Shopping ads and, in some instances, on product listings on Google. These ratings help shoppers with their purchase decisions, driving more qualified shoppers to your product pages.
How Product Ratings work
Product Ratings appear as a 1-5 star rating system and a count of total reviews. These star ratings represent aggregated rating and review data for the product, compiled from multiple sources including merchants, third-party reviews aggregators, editorial sites and consumers.
While the overall shopping experience may include deliveries, returns, and customer service, Product Ratings are related to specific products, and not to your store or business. If you are interested in finding out how to surface ratings for your business, learn more about Seller Ratings.
Star ratings may not always show. We’ll show star ratings when our system determines that the rating information is accurate and relevant for shoppers’ needs.
How matching works
The reviews data from a Product Ratings feed is matched to products based on a number of factors, the strongest being globally unique product identifiers such as GTINs. Without GTIN data, Google will attempt to match a review through other metadata information such as SKU, Brand + MPN pairs and product URLs, though these identifiers generally do not offer a good match. In short, without GTINs, matching issues may occur. What this means is that you may not see star ratings appear alongside the products your business offers.
