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 hosting account's hPanel and locate the Subdomains menu in the Domains 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 and remove it in List of Current Subdomains section:
That’s it, now you know how to create and manage subdomains on hPanel!
