Setting up the Google Shopping app
The Google Merchant Center is a tool that helps you upload your store and product data to Google and make them available for Google Shopping campaigns and other Google services.
Shopify's Google Shopping app asks you to log in to your Google account to sync your Shopify store with your Google Merchant Center account. If you don't already have a Google Merchant Center account, then an account is created for you during setup.
The Google Shopping app automatically adds conversion tracking events to your Google Ads account when you set it up. If your store already has Google conversion tracking set up through edits to the theme code or through a third-party app, then the conversion tracking events might be duplicated and your report data will be inaccurate. You can disable duplicated conversion tracking events from your Google Ads account. Learn more about conversion settings from Google Ads Help.
Syncing your Google Merchant Center account
When you set up the Google Shopping app, Shopify syncs your products and relevant Shopify store settings like shipping and taxes to the Google Merchant Center.
Syncing your domain
Each Google Merchant Center account needs to be associated with a verified domain that isn't associated with another account. To set up the Google Shopping app, your Shopify store's domain needs to be claimed, which means it's reserved for use with the Google Merchant Center account that you added to the channel.
When you're setting up a new or existing Google Merchant Center account with the Google Shopping app, your Shopify store's domain is claimed automatically unless it's associated with a different Google account. If your domain is associated with a different Google account, then you need to claim the domain for the account that you want to use with the Google Shopping app. After a domain is claimed, you can't use that domain with any other with another Google Merchant Center account.
You can read more about verifying and claiming your domain from Google Merchant Center Help.
Syncing your product feed
The Google Shopping app syncs your products in a separate step after your Merchant Center Account is connected. If you already have a product feed set up, then it is overwritten to avoid conflicts between your Shopify store and your Merchant Center account. For more information about managing which products are synced, see Syncing your products.
Products marked as
pending in the new Google Shopping app after migration
After you migrate to the new Google Shopping app, products that were approved on the old Google Shopping app might be marked as
pending in the new Google Shopping app. The old Google Shopping app only synced the first variant for a product, but the new Google Shopping app syncs all of the variants for a product. Until all of the variants are reviewed by Google, the product is marked
pending in the new Google Shopping app. The product that was approved in the app is still approved by Google. Syncing the new variants can take up to a week.
