What happens when you link Merchant Center and Google Ads

• Only a Merchant Center account user can request to link the accounts. New account link requests will appear in your Google Ads account on your "Linked accounts" page, which is located in the Settings drop-down menu.

• Once the Google Ads account owner approves the request, some information is shared between accounts. The Merchant Center's product information is available in Google Ads for campaign creation. Certain Google Ads statistics like clicks are shown in the linked Merchant Center account.

• Google Ads account owners and either admin or standard Merchant Center users can remove the link at any time. Neither party can make changes in the other linked account. For instance, the Merchant Center account owner cannot pause or start campaigns, or make changes to bids in the linked Google Ads account.
• If you remove the account link, Shopping campaigns that rely on product data from this Merchant Center account will stop serving ads. You also won't be able to create new campaigns in Google Ads based on product data from this Merchant Center account.

Before you begin

You'll need:

• Access to a Merchant Center account
• You’ll need to have admin access to your Google Ads account to link Google Ads and Merchant Center accounts. If you don't have admin access, you can ask the administrator of your Google Ads account to grant you access, or to link the accounts for you.

Instructions 

Below you can learn how to: 

• Request to link to AdWords from Merchant Center
• Approve link requests from Merchant Center in AdWords
• Manage links between accounts
• Track link statuses

Request to link Merchant Center to AdWords

You'll need to initiate the link from Merchant Center. You can link multiple AdWords accounts to a single Merchant Center account, and a single AdWords account can be linked to multiple Merchant Center accounts.
