Ensuring your product feed is fit for Google Shopping is a very important procedure in gaining stars in your Google Shopping product listings.

Once you have connected your Product Feed to Reviews.io through one of our integration methods, you will need to collect 50 product reviews that pass Google Shopping's criteria.


Google have their own criteria for Product Reviews to be eligible, so the Reviews are run through an approval process on our side before they make it into the Product Ratings feeds.


It checks a couple of things, such as the review length, content, formatting and use of punctuation. For a Product Review to be eligible it can't talk about the company, delivery practices, returns process, pricing or other aspects of the service that are not directly related to the product itself.

Once you have reached the requirement and your feed is incorporated into the Google Shopping system (this can take a matter of weeks and is entirely dependant on the Google Product Ratings Team), it is then assessed by Google. If it runs with low performance, your star ratings will not be available on Google Shopping.

This usually happens when the product reviews feed and/or shopping feed do not contain sufficient product identifiers (GTINs or MPN [Manufacturer Part Number]/brand information).

Product identifier information is critical information that allows Google Shopping to match the ratings to the corresponding products.

In order to improve the performance of your feed, we recommend that you check if your shopping feed (product feed uploaded to their Google Merchant Centre account) contains strong product identifiers (either GTIN or MPN + brand) and if not to include those to allow matching.

In conclusion, your feed files must meet one of the following criteria in order to display star ratings on your ads. (The most recommended method is the first one listed below. Other metadata information such as SKU, Brand + MPN pairs and product URLs, generally do not offer a good match).

  1. Your product reviews feed and shopping feed contain identical GTINs.

  2. Your product reviews feed and shopping feed contain identical MPNs and Brands.

  3. Your product reviews feed and shopping feed contain identical SKU and Brands.

  4. Your product reviews feed and shopping feed contain identical product URLs.
