Guide to Linking a Squarespace Domain with a GitHub Pages Website

This article offers a practical, step-by-step guide for users who wish to connect a custom domain purchased from Squarespace to a website hosted on GitHub Pages. First, the article explains the prerequisites, which include having a functioning GitHub Pages site and access to both GitHub and Squarespace admin dashboards. It differentiates between user and project GitHub Pages URLs and emphasizes the importance of ensuring your site is live. Next, users are instructed to create a CNAME file in their repository, which tells GitHub about the custom domain. Since Squarespace doesn’t support CNAME flattening or ALIAS records, the article provides four specific A record IP addresses to be used instead. Users must then log into Squarespace, access DNS settings, and replace default records with the GitHub ones—making sure to remove conflicting entries. DNS propagation times are discussed, noting it may take up to 48 hours for the changes to take effect. Finally, the article offers troubleshooting tips for common problems such as 404 errors or HTTPS issues. This tutorial enables non-technical users to integrate a professional domain name with a free, reliable hosting solution.
