Hosting multiple websites on a single web hosting account can save you money. It also lets you manage both the billing and the technical control panel for your sites in a single location. The hosting company GoDaddy, which is also the world's largest domain registrar, allows Deluxe, Premium and Ultimate hosting accounts to host more than one site by pointing their domain names to the accounts' sub-folders. If you have an Economy hosting account, you must first upgrade to one of the other plans.
Log in to your GoDaddy account and go to the "My Account" page.
Click on "Hosting" on the left side of the page under "My Products," then click on "Manage Account" and choose "Domain Management" under "Settings."
Click "Add Domain." Enter the new domain name in the field marked "Domain," and enter the sub-folder that will contain the site in the "Folder" field. Click "OK" to complete the process.
