How to use my hosting with more than one domain name?
You can host multiple domains on your hosting by adding them from your Client Area > Websites > Add New Website.
SiteGround allows you to host unlimited domains with our hosting solutions, except on the StartUp shared hosting plan.
Note that if you wish to have a new domain name pointed to your website, you need to register this domain first. To register a domain with SiteGround go to your Client Area > Services > Domains > New Domain.
