In order for visitors to see your website when they visit your domain, you need to make sure your domain and website are connected. You can accomplish this by pointing your domain name (and, therefore, your visitors) to your website.
If your website is not yet built, you have several options. For example, you can fill out a form to create a one-page Business Profile and point your domain to the profile until your website is ready. You can also have your domain point to an Under Construction page until your website is ready for viewing.
If your website is located with a different service provider, you can edit your DNS (Domain Name Servers) to connect, or point, your domain name to the name servers of a different hosting provider.
