Mobile redirect or different content from desktop

Google sees one product on desktop and a different one (or a redirect) on mobile. Google blocks listings where mobile and desktop disagree.

Old separate-mobile-domain setups (m.example.com) where the mobile redirect points at the wrong product page, or category pages instead of product pages.

1. Audit mobile redirect rules — every desktop product URL must map to the same product on mobile.
2. If you use a separate mobile domain, consider migrating to responsive design.
3. Test with Google's mobile-friendly tool to confirm mobile shows the same content.
