How to fix: Mismatched domains

The landing page URL's domain doesn't match the verified domain associated with the Merchant Center account.

Google's crawler couldn't process the URL you submitted in your product data. Common triggers: invalid characters (spaces, ampersands, hash fragments), relative paths, missing protocol (http:// or https://), URL-encoded entities placed incorrectly, or hostnames that don't resolve.

1. Test the URL by pasting it into a private/incognito browser window — if it doesn't load cleanly, Google won't load it either.
2. Make sure the URL starts with `http://` or `https://` and the protocol is whitelisted in Merchant Center settings.
3. URL-encode special characters (spaces → %20, ampersands → %26) using your platform's URL builder.
4. Remove tracking parameters that include user-specific data — keep URLs clean and shareable.
5. Re-upload your feed or fix the affected products one-by-one in Merchant Center → Products → Needs attention.

• Hash fragments (#section) — Google strips them, leaving the rest of the URL intact only if structurally valid
• Smart quotes from copy-paste — invisible to humans but trigger validation failures
