Additional domains, subdomains and aliases serve different purposes. This guide explains the differences and how you can use them.
An additional domain
An additional domain is connected to your hosting account but can serve a separate website from your primary domain. Its content and document root can be independent. Search engines evaluate the actual content and configuration rather than the hosting account alone. You can add an additional domain in cPanel.
A subdomain
A subdomain lets you create an address below an existing domain, such as blog.example.com or support.example.com. It can serve a separate section or application without registering another domain. Its content need not be related to the main site. You can add a subdomain in cPanel if your hosting plan permits it. You need control of the parent domain and its DNS; if necessary, first register a domain to use as the parent. Example:support.capconnect.com is a subdomain of capconnect.com
Alias
An alias, also called a parked domain, is another domain name configured to display the same website. It does not need to differ only by its extension. If multiple names show identical content, use an appropriate canonical or redirect strategy. Example: capconnect.com capconnect.ma
Check the result and troubleshoot
Creating a domain in cPanel does not register it with a registrar. Check the document root, DNS and HTTPS certificate separately. Menu labels can differ between Jupiter and Meridian.
