What is Google Merchant Center
Google Merchant Center (GMC) is a platform where online retailers submit their product catalogue to Google. The product data submitted to GMC powers Google Shopping ads (Product Listing Ads), free product listings in the Shopping tab, Google Images product results, and Performance Max shopping campaigns.
The flow: you submit product data → Google reviews and approves products → approved products become eligible to appear in Shopping results → you create Shopping or Performance Max campaigns in Google Ads linking to your GMC account → Google serves the ads in relevant searches.

Account Setup
Create a Google Merchant Center account at merchants.google.com. Required information:
- Business name. Your legal trading name as it appears on your website — must match the website's business name for verification.
- Business country. Where your business is based — determines the default currency and some policy requirements.
- Business type. Online store, physical store with online presence, or physical store only. Determines which features and policy requirements apply.
- Time zone. Used for reporting and scheduled feed refreshes.
Merchant Center Next
Google launched Merchant Center Next in 2024 as the updated interface for GMC. It combines product management, performance data, and campaign creation in a unified interface. New accounts are created in Merchant Center Next by default. Classic Merchant Center will be deprecated — if you have a classic account, migration to Next is recommended.
Website Claim and Verification
You must verify ownership of your website before products can be approved. Verification methods available:
- Google Analytics. If GA4 is installed on your site with the same Google account, GMC can verify ownership automatically.
- Google Tag Manager. Same — if GTM is installed with the same account, automatic verification is available.
- HTML tag. Add a meta tag to the
<head>of your homepage:<meta name="google-site-verification" content="[code]" /> - HTML file. Upload a specific HTML file to your website's root directory.
After verification, you "claim" the website — this prevents other Merchant Center accounts from claiming the same URL and ensures product data is associated with the verified site. Only one GMC account can have a claimed domain — if you are migrating between accounts, unclaim from the old account first.
Shipping and Tax Configuration
Shipping and tax settings must be configured accurately before products can serve Shopping ads. Google checks that the shipping costs and tax rates shown in Shopping ads match what is shown on your website at checkout.
Shipping settings
Configure shipping in Merchant Center under Shipping and Returns. Set up shipping services matching your actual shipping options: free shipping thresholds, flat rate shipping by weight/price, carrier-calculated rates. Google requires that the shipping cost shown in the ad can be verified on the landing page — if your ad shows "Free shipping" but the landing page shows shipping charges, the discrepancy triggers a policy violation.
Tax settings (US)
For US merchants, configure tax rates by state. Options: manual state-by-state rate configuration, use a US tax table (automated), or set a blanket rate. The tax shown in Shopping ads must match what is shown at checkout for the user's location.
