A domain alias is the same as a parked domain — it points an extra domain at an existing site.

1. Log in to cPanel and go to Domains > Aliases.
2. Type the domain you want to alias.
3. Click Add Domain.

Visitors to the alias see your main website content.

Tip: Aliases share content; addon domains (article 59) host separate content. Choose based on whether you want one site or two.
