Correct an existing feed

Stay organized with collections Save and categorize content based on your preferences.

Summary

If you already have a product feed, you may need to reformat its content to match the format that Google expects. This section explains how you can use an existing feed with your Merchant Center account. You can only do this through the Merchant Center UI.

See the Common issues section for a list of the most common product data issues.

Manual steps

  1. Choose one of our Supported file formats.
  2. If your existing feed doesn't match a supported format, convert it to one that does.

    • If items in your existing feed don't match the Product data specification, you can set up feed rules to reformat your product data automatically. You may have to format some feed data manually.

    • You can remove any information from your feed that Merchant Center doesn't require.

    • If your existing feed is missing required information, add it before you upload the feed.

  3. Upload a feed to Merchant Center.
