Merchant Center is able to automatically verify and claim some retailer websites during the account setup process.
How it works
If Google already has the information that it needs to verify your site (e.g. if you use Google Analytics on your site), you'll see a notification letting you know that your website has been automatically verified after you enter your site's address on the 'Business information' page.
In some cases, you'll also receive an email from Search Console, a Google tool, letting you know that Merchant Center has created an account for you. Merchant Center verifies your site through Search Console.
You can log in to Search Console at any time to review your account's verification settings and users, or to explore its Google Search optimisation and performance tools.
Troubleshooting
If automatic verification fails at any point, you'll see a notification in the UI inviting you to verify and claim manually. Learn how to verify and claim your shop's website
