I submitted products to google and some of them are not approved and one of reason said “Your domain is not claimed by Google Merchant Center. Please contact Shopify support.”
At google merchant center, my site is verified and claimed already. any help?
When you log in to Google Merchant Center, and it says not claimed and or verified, then this is the case.
Click on the Fix It button in the red banner, then follow the instructions. The easiest way is via Google Analtytics, but you can also add a meta tag to the theme.liquid file.
Simply follow the steps.
