If you are changing a website’s domain name, you can use Google’s address change tool to identify the new site address.
Transferring the authority from the old site to the new one and showing Google that the site’s address has changed is a helpful factor for minimizing traffic loss during the domain change process.
1. Go to Settings > Address Change from the console panel (or click on this link directly).
2. On the address change page, select the domain name to which you want to redirect. (The new domain must have to Search Console account.)
3. When you click the ‘Verify and Update’ button, if the old domain hasn’t been redirected to the new domain with a 301 status, the following warning screen appears. A 301 redirect is a required step for this action.
4. After the 301 redirect is set, all steps are completed, and Search Console displays the following screen below, indicating that the address change process is complete.
