Adding domains to your GoDaddy hosting plan can be done by following the steps Ken Applebee outlines in this video tutorial. Once at the GoDaddy main home page, click on My Hosting Account under the Hosting tab at the top of the screen. Log in and go to your account with the hosting on it. Click on Your Domains and you will see your domain in there. On the right side you can choose to add a subdomain or you can just click on the Add Domain tab for a completely separate domain. This allows visitors to your web page to access content on your site at a completely new URL. This feature is part of a premium plan.
