If you manage a cPanel hosting account, subdomains are one of the most powerful features at your disposal. They let you run multiple independent websites, web applications, or test environments under a single domain — without needing separate hosting plans. Whether you’re setting up a blog at blog.yoursite.com, a client portal at portal.yoursite.com, or a staging environment for development work, subdomains give you the flexibility to organize everything under one roof.
In this guide, you’ll learn exactly how to create, configure, and manage subdomains in cPanel. We’ll cover the underlying DNS mechanics, folder structure best practices, common pitfalls like redirect loops and SSL issues, and how to use subdomains with addon domains so you can get the most out of your hosting account.
