Custom Domain Setup

You can connect any domain or subdomain that you own to your Ghost(Pro) blog by adding a CNAME record to your domain's DNS records. We will automatically provision SSL certificates for any correctly configured domain.

Note: We do not support the use of A records for custom domain setup.

The following guide explains how to setup your custom domain with your Ghost(Pro) publication.

  6. Once you’ve setup your CNAME record within your DNS records, click Activate custom domain to activate your custom domain with your Ghost publication.

    If the activation fails, you will receive an error message in red indicating what needs to be corrected. For custom domain troubleshooting, please see the list of common errors (and how to fix them) below.
