Seller ratings on Google Shopping

Seller ratings on Google Shopping may be based on one or more of the following sources:

  • Shopping reviews for your shop domain, which include reviews from various third-party sources.
  • Google Certified Shops, a free certification programme that can improve your conversion rate and average order size by reassuring potential customers that you offer a great shopping experience.
  • StellaService, an independent company that rates the customer service performance of online businesses.
  • Ratings from Google Consumer Surveys, a market research tool that allows businesses to easily create, run and analyse the results of surveys across the web. These ratings can also help people make more informed purchasing decisions. Google uses this platform to collect ratings at least once a year for certain domains and businesses. Learn more.

We do not modify existing reviews. We connect users with reviews from seller ratings websites. To provide consistent ratings, we rescale ratings on a 1-5 scale and filter out reviews that Google considers to be untrustworthy or otherwise questionable.

Ratings for your shop may appear automatically without any action required by you, if they are not already present. As we develop this programme, we will continue to enhance and refine our ratings. We expect the number of shops rated on Google Shopping to grow as we update this feature.

If you don’t have reviews for your shop yet, you can sign up for Google Certified Shops, a certification programme which collects seller ratings for free.

The seller ratings calculation in Google Shopping results

We want our seller ratings to reflect more than just an average of review scores. That's why we also factor in the quality of the reviews themselves, and how representative they are of customers' shopping experience. We're constantly refining how we use those signals to give our users the most helpful overview possible.

Troubleshooting shop ratings

Below are some common issues that you might encounter with Seller Ratings and Google Shopping.

Incorrect ratings

If you have found ratings that you believe to be incorrect, you will need to contact the site which hosts the ratings to resolve the matter. You cannot respond to individual seller reviews on Google Shopping. To respond to a seller review, go to the seller rating website and respond to the seller review. At present, we do not display merchant responses to seller reviews in Google Shopping results.

If you believe that Seller Ratings from a different shop are appearing with your products, please make sure that your shop name and registered domain in your Google Merchant Center account are different from the other shop on the third-party seller rating websites. If this information matches and you are unable to make changes, please contact us to investigate this further.

My seller ratings are not appearing

Reviews are not added to Google Shopping results in real time, so you may notice a delay between receiving a new review and its addition to your rating in the Google Shopping results. The same is true when a review is removed from a seller rating website. If you notice that your reviews have stopped appearing, please make sure that the shop name and registered domain match in your Google Merchant Center account and the third-party seller rating websites. Learn more about how to update the shop's name and website URL in the Google Merchant Center account settings.

For Google Shopping star ratings to appear, your business typically needs at least 30 unique seller reviews, each from the past 12 months. However, we may show ratings for merchants with fewer than 30 reviews if we have sufficient data from other sources to determine an accurate rating.
