An add-on domain is a separate domain name you add to an existing web hosting subscription or web hosting plan. Addon domains allow you to control multiple domains from a single account.

An addon domain links a new domain name to a subdirectory of your account’s public_html (document root) directory, and then stores its files in that subdirectory.

The addon domain will appear as a totally separate domain from your primary domain. There should be no evidence that your domain is an addon domain to incoming traffic when they visit your addon domain.

When you create an Addon domain, three things happen:

  1. a folder is created in the ‘public_html’ directory
  2. a subdomain is created for the primary domain and attached to the new folder
  3. the new domain name is associated with the subdomain

For example, if the primary domain was’ and you assign the Addon Domain’ to the folder ‘123’, the following routes (URLs) would be true:


All three of these paths would access the same directory and show the same website. However, in concern to your site’s viewers going to, there is no evidence that they are being routed through, and everything will function as normally.

What can I use an add-on domain for?

An add-on domain has the same functionality as a full hosting subscription. You can use it to:

  • Create another website – You can make a second website with Website Builder, create email addresses and set up a Gallery. Though you share the disk space of the hosting package, an add-on domain has a separate space and FTP login.
  • Attract more visitors with a redirect – You can redirect an add-on domain to your existing website to generate more traffic. For example, register a domain with a common misspelling of your primary domain. That way your visitors will still end up on your website, even if they have typed your domain wrong.
