How to use my account with more than one domain name
You can host multiple domains on your hosting account by configuring them as Addon Domains in cPanel.
SiteGround allows you to host unlimited Addon Domains with our hosting solutions, except on the StartUp shared hosting plan.
Please note that if you wish to have a new domain name pointed to your account, you need to register this domain first. To register a domain with SiteGround go to your User Area -> Add Services -> Register a Domain.
