Fix mismatched domains in Merchant Center

Symptom

Products point at a domain or subdomain Google does not consider the verified website for the Merchant Center account.

Exact cause

Google flagged this state because the website URL configured in your Google Merchant Center account does not match your Shopify store's domain. This can prevent all your products from being approved for Shopping ads and free listings.

This often comes from wrong primary domain settings, redirect chains, subdomain drift, or market-specific domains that were never re-verified.

Which system wins

For domain ownership and landing-page trust, Google needs the claimed Merchant Center website and the live canonical product URLs to agree. The landing page itself must also be publicly crawlable.

Correct edit point

Update the claimed website in Merchant Center, confirm the Shopify primary domain, and make sure canonical product URLs resolve cleanly on that same domain.

Manual fix steps

1. Open Google Merchant Center → Settings → Business information → Website.
2. Verify the URL matches your Shopify store's primary domain (not the .myshopify.com URL).
3. If you recently changed domains, update the Merchant Center website and re-verify ownership.
4. Ensure your domain is verified in Google Search Console and linked to your Merchant Center account.

Validation steps

1. Update the source-of-truth system first.
2. Verify the landing page or structured data now matches the intended value.
3. Check Merchant Center diagnostics after the documented reprocessing window.
