A subdomain is an address that sits in front of your main domain — like shop.yourdomain.com or blog.yourdomain.com. They’re perfect for running a distinct section of your site, a staging environment, or a separate application. Creating one in cPanel is quick.
What a subdomain is good for
Subdomains behave like separate sites while still belonging to your main domain. Common uses include a blog (blog.), an online store (shop.), a customer portal (portal.), a knowledge base (help.), or a private staging copy (staging.). Each gets its own folder and can run its own application.
Creating the subdomain
- In cPanel, open Subdomains (or Domains on newer panels) under the Domains section.
- In the Subdomain field, type the prefix you want, such as
shop. - Choose the domain it belongs to from the dropdown.
- The Document Root auto-fills — this is the folder where the subdomain’s files will live. Leave the default unless you have a reason to change it.
- Click Create.
Putting content on your subdomain
The subdomain now points to its own empty folder. Upload your files there via File Manager, or install an application like WordPress into it using Softaculous — just select the subdomain as the install destination. Within minutes you can have a full separate WordPress site running under it.
SSL for the subdomain
Your subdomain needs its own SSL coverage so it loads securely. AutoSSL usually issues a certificate for new subdomains automatically within a few minutes. Check SSL/TLS Status and, if the subdomain isn’t yet covered, tick it and run AutoSSL.
DNS propagation
Because subdomains are created on your own server, they usually work almost immediately, without the long DNS wait a brand-new domain needs. If it doesn’t resolve straight away, give it a short while and clear your browser cache.
Removing a subdomain
To delete one later, return to the Subdomains page and remove it. Note that deleting the subdomain doesn’t automatically delete its files — you’ll need to clear the folder in File Manager separately if you want the space back.
