Yes, you can use a subdomain for a SiteGround Website Builder or Ecommerce website as long as it meets the following criteria:

  • The subdomain is not already in use for another website as a primary, parked, or subdomain.
  • The parent domain is not used in another SiteGround Client Area.

If the subdomain fulfills these requirements, you can set it as the primary domain of a SiteGround Website Builder or Ecommerce website.

  1. Navigate to your Client Area > Websites.

IMPORTANT! We recommend using а subdomain of a parent domain that is – pointed to the SiteGround nameservers. In this case, the subdomain’s DNS records and SSL will be created automatically, and your website will be accessible shortly.

If the parent domain’s DNS records are managed elsewhere, please contact support for follow-up instructions.
