Subdomains, Addon Domains and Parked Domains in cPanel

Four options, four purposes

• Subdomain — a section of your existing domain such as shop.yourdomain.com or staging.yourdomain.com. Free, unlimited on most plans, and served from its own folder.
• Addon domain — a completely separate website hosted inside the same account, with its own document root and email.
• Alias (parked) domain — a second domain that shows the same website as your primary. Perfect for alternative extensions and typo protection.
• Redirect — no hosting at all, just a 301 or 302 pointing visitors somewhere else.

Creating a staging subdomain

• 1 In cPanel open Domains and click Create A New Domain.
• 2 Enter staging.yourdomain.com and let cPanel set the document root to a folder outside public_html for cleanliness.
• 3 Issue an SSL certificate for the new hostname via AutoSSL.
• 4 Password-protect the folder and add a noindex header so search engines never index the copy.

Never leave a staging copy publicly crawlable — duplicate content and accidental orders are both real risks.

SEO handling for aliases

Aliases serve identical content on two hostnames, which is duplicate content unless handled. Set a canonical tag to your primary domain, or better, redirect the alias with a 301 at the server level and keep only one indexable hostname.

Frequently asked questions

Do addon domains need their own hosting plan?

No, they share the resources of the account they live in. Plans differ in how many addon domains they allow.

Can a subdomain have its own SSL certificate?

Yes. AutoSSL issues certificates per hostname automatically, and wildcard certificates cover all first-level subdomains.
