It sounds like you have two Google accounts and two Google Merchant Center accounts being used with different emails. If you’re not actively using these accounts, you can follow the steps given in the channel to transfer the domain to the new account.
Topic summary
Main issue: Users receive the error “Your domain is already claimed by a different account” when connecting Google Merchant Center (GMC) via the Google & YouTube app on Shopify, prompting a “transfer my domain” option.
Likely cause: Using multiple Google accounts/GMC accounts with different emails. GMC is the platform for managing product data for Google Shopping; “domain claim” verifies website ownership in GMC.
Guidance shared:
- If the old GMC account isn’t actively used, follow the app’s steps to transfer the domain to the intended account.
- Do not transfer if the original account is suspended; connect the app to the correct original email instead.
- Creating a new GMC when an old one is suspended may lead to a permanent ban.
Disagreements/clarifications:
- Changing domain ownership or email in Namecheap is likely not relevant; one user notes the domain is linked in both Shopify and Google, suggesting the issue is account-level in GMC.
Status: Multiple users report the same problem and inability to proceed. No confirmed resolution; action depends on the suspension status and identifying the correct original GMC account.
