What is a Subdomain?

A subdomain is an extension of your main domain. For example, if your domain is yourcompany.com, you can create:

  • blog.yourcompany.com → For a separate blog
  • shop.yourcompany.com → For an online store
  • app.yourcompany.com → For a web application
  • dev.yourcompany.com → For development testing

Subdomains are free and unlimited with your PlatiniumHost plan.

How to Create a Subdomain in cPanel

  1. Log in to cPanel
  2. Find the "Domains" section
  3. Click on "Subdomains"
  4. In the "Subdomain" field, type the prefix. E.g.: blog
  5. Select your domain from the dropdown menu
  6. The Document Root will be filled automatically (e.g.: public_html/blog)
  7. Click on "Create"
✅ Done! Your subdomain blog.yourdomain.com is now created. cPanel automatically creates the folder public_html/blog/ where you should upload the files for that subdomain.

How to Install WordPress on the Subdomain

Once the subdomain is created, you can install WordPress or another application on it using Softaculous. When choosing the installation domain, select the subdomain you just created.

???? SSL for Subdomains: After creating the subdomain, go to cPanel → SSL/TLS Status and run AutoSSL to automatically install the HTTPS certificate on the subdomain.
