Pointing another name at your site.
BEFORE YOU START
The domain registered, with nameservers pointing here.
WHERE
cPanel, Domains, or Aliases depending on your version.
WHAT HAPPENS
The domain is added to your main site's configuration.
Visitors to it see your main site.
WHAT TO DO NEXT
Decide whether it should serve the same content or redirect.
Redirecting is usually better.
HOW TO REDIRECT IT
cPanel Redirects: select the alias domain, redirect permanently to your main domain.
Or a rule in .htaccess.
WHY REDIRECT RATHER THAN SERVE
Two domains with identical content splits search ranking.
A redirect consolidates it.
RUN AUTOSSL
Every alias needs certificate coverage, including for the redirect itself.
Without it, visitors reaching the alias over HTTPS see a warning before the redirect happens.
FOR MAIL
An alias domain can receive mail. Decide whether you want that.
