Select a New Primary Domain
Selecting a primary domain allows you to choose one domain as the main redirect point. This means that if you own multiple custom domains, you can choose the site name that best represents your business or organization.
1. Navigate to the Settings panel by clicking the gear icon in the gray navigation bar.
2. Select the Domains tab under the Settings header.
3. All of your domains will be listed. To select a primary domain, toggle the button under the Primary column, and make sure your selected primary domain is toggled onto blue.
