Fix “Mismatched domains” in Google Merchant Center
Typical Merchant Center message: Mismatched domains
Reviewed October 14, 2026 against Google’s published rules.
Google reports mismatched domains when the landing page URL in your product data uses a domain that does not match the website registered in your Merchant Center account.
Common causes
- No website URL is registered in the account yet. You need to verify and claim your website first.
- The registered URL differs from the links in your data source. To submit http://www.example.com/item1.html, you register http://www.example.com/.
How to fix it
- Check the website URL under your business information in Merchant Center, and claim it if it is not claimed.
- Open Products, then Needs attention, and filter for this issue.
- Change each product link so it uses your registered domain.
- Image links may point to another domain. Google says images hosted off your registered domain can still be used with the image link attribute.
- To fix many products at once, download the .csv list of affected products from the Needs attention tab, correct your product data and re-upload it.
- Google says it can take 24–72 hours for a fix to leave the Needs attention list.
