Upload a product reviews feed to Merchant Center

A custom icon for Merchant Center Classic Article Header.

A product reviews feed is needed to show aggregated reviews of your products to customers shopping on Google. Eligible accounts can upload a product reviews feed to Merchant Center.

Before you begin

Sign up for the Product Ratings program using the Product Ratings Interest Form. Before signing up, make sure you have at least 50 product reviews.

Feed prerequisites

  • Use a validated product reviews XML file. Learn more about XML validation and creating your XML feed.
  • You must host your own XML feed, and the URL of your file location must begin with "http://", "https://" or "sftp://".
  • You can use a single XML file or multiple XML files compressed into a .zip file.
  • Under no circumstances should the size of a single XML file exceed 100 MB, even if it's contained in a .zip file. A .zip file containing multiple XML files may be over 100 MB in size. Any single XML file that exceeds the 100 MB size limit won't be processed.
  • Each single file must be a fully-contained, valid XML file. Refer to the feed specifications for details on what each XML file should include.

    • Properties: This includes key feed properties, which vary depending on the input method of the feed. Here, you can find attributes such as input method, time zone, file size, detected delimiter (if applicable), and more.
    • Attributes: Depending on which Merchant Center program your feed is opted into, we require attributes to adhere to the product data specification. In this section, you can review all of the attributes we found in your feed, including those attributes which are recognized and map to the feed specification, and also unrecognized attributes which don’t match any of those listed in the data specification.
    • Processing Data: In this section, you can review the amount of items found in your feed as well as those with any detected item issues. Review the list of item issues to understand how many items in your feed are impacted, including examples and links to documentation to address the issue.
Note: Whether you choose a scheduled fetch or a direct upload, you'll need to upload a feed at least once a month so that you'll remain eligible to participate. Make sure the file name you provide includes the appropriate extension (.zip for a ZIP file and .xml for a single XML file). Learn more about uploading data feeds

After you've registered a new feed, it'll appear in your list of registered feeds in the "Feeds" screen. A feed can be in the following states:

  • Processing: Indicates that feed validation is in progress.
  • Processed: Indicates that Google has successfully received and validated the feed.
  • Failed: Indicates that feed validation wasn't successful and the feed content won't be processed further. You must correct the feed and upload the file again.
Note: To delete an existing review, simply exclude it from your uploaded feed. Previously submitted reviews that aren't included in new uploads will be removed.
