To link Google Ads to Google Merchant Center, identify the correct accounts, confirm that you have the necessary permissions, and use the account-linking options available in Merchant Center or Google Ads.
Do not create replacement accounts simply because the original connection is unclear. First establish which accounts belong to the business and which ones currently receive product data.
Before you start
Record the Merchant Center account ID and Google Ads customer ID. Check the domain, business name, and people managing each account.
You may have access to several accounts through the same Google login. The email address alone is not enough to identify the correct destination.
Google notes that Google Ads administrative access is needed for linking. If another person controls that account, coordinate the request with them.
Start the link from Merchant Center
Google’s guidance describes account creation or linking through the Ad campaigns area and service-linking options. Interface labels can change, so use the current account-linking help alongside your own screen.
Choose the existing Ads account when it is the business’s intended advertising account. Follow the prompts and review whether the flow involves Merchant Center only or a broader Business Manager connection.
Do not assume those scopes are interchangeable.
Complete any pending request
A link that has been requested may still need acceptance by an authorized person. Check the status in both services where available.
If the connection is not complete, confirm the IDs before trying again. Sending repeated requests to the wrong account is unlikely to solve a permission problem.
Keep the business owner informed about the relationship being created.
Verify the result
Inspect the connected account details and confirm the expected Merchant Center account is available to the relevant advertising workflow.
Then check a small product sample. The connection should be evaluated separately from the catalog’s approval status and any campaign settings.
A connected account with no eligible products still requires catalog work.
Troubleshooting common problems
If an account is missing, check whether you are signed in to the correct Google account and hold the required access level.
If products are missing, inspect the Merchant Center catalog and data-source settings before changing the link.
If a previous agency is involved, request documented access or ownership clarification rather than deleting existing relationships without understanding their role.
Frequently asked questions
