Subdomains allow you to easily manage parts of your website and make your link look great at the same time! For example, instead of having the introduction page of your site look something like this - mysite.com/a/intro - you can just create a subdomain for that part of your website - intro.mysite.com. Subdomains can also act as fully independent websites.
To create a subdomain, access your cPanel account and click on Subdomains section:
Here you can choose a domain for your new subdomain as well as specify a custom directory for it.
Once the subdomain is created, you can check information about it, remove it or create a redirection in Modify a Subdomain section:
That’s it, now you know how to create and manage subdomains on cPanel!
