How do I verify my domain with an HTML page?
Log in to the Partner Centre and choose Your Account > Domain Verification. Choose Option 2: "Add a new HTML page to your domain". A new HTML string will be created for you.
Add this file as a page to your domain. Example: www.yourwebsite.com/awhgret893qygwaf8o7asfblq4.html.
Save his new HTML page and then click the "verify HTML page" button.
Once you've done this, our crawlers will search for the html page. If found, ownership of the domain is automatically confirmed. If not, the automated verification process will fail and you will need to request manual verification.
