Before you can start using certain programs in Merchant Center, you need to verify and claim your store’s website URL. Verification lets Google know that you are an authorized owner of a website URL. Claiming associates the verified website URL with your Merchant Center account.
How it works
If you have never verified your website URL with Google before, you’ll start by verifying your website. To do this, you’ll choose one of four ways to allow Google to communicate with your website. These methods add markers to your site so that Google can find your site, and confirm that you are the authorized owner of both your website and your Merchant Center account. This code does not give Google any other sort of access or permissions.
To complete the process, you’ll claim your site. That means you’re reserving the URL you’ve verified for use with your Merchant Center account. Note
