How to Set Up a Squarespace Subdomain
TL;DR:
- A subdomain adds a prefix to your main domain, like 'blog' in blog.yourdomain.com
- Subdomains in Squarespace can't be your primary domain if they share billing with the main site
- You can point a subdomain to your homepage, another page, or an external site
- Create, edit, and delete subdomains directly from your Squarespace dashboard
- If domain forwarding isn't available, you'll need to add DNS records manually
A subdomain creates a unique web address under your existing domain. If your main site is yourdomain.com, creating blog.yourdomain.com makes "blog" the subdomain. Beyond the common "www", you can customise subdomains for different sections like blogs, shops, or support areas.
Creating a Subdomain
Here's how to set up a subdomain in Squarespace:
- Log into your Squarespace account and go to the Domains dashboard
- Select the domain you want to modify
- Go to Website settings and scroll to Domain Forwarding Rules
- Click 'Add rule' and verify your identity if prompted
- Enter your subdomain (like "blog") and your root domain
- Choose whether the redirect is temporary (302) or permanent (301)
- Make sure SSL is turned on for security
- Save your settings
Quick tip: If you can't see Domain Forwarding Rules, you'll need to add your subdomain through DNS settings instead. This happens when your domain is connected via Nameserver or DNS Connect.
Editing and Deleting Subdomains
To edit a subdomain:
- Go to Domain Forwarding Rules
- Click 'Edit' next to your subdomain
- Make your changes and save
To delete a subdomain:
- In the same section, click delete next to the subdomain
- Confirm your choice
Adding a Subdomain Manually
If your domain uses DNS Connect or Nameserver Connect, you'll need to add the subdomain manually:
- Go to your domain settings and find DNS settings
- Add a new custom record
- Put your subdomain name in the Host field
- Add
ext-sq.squarespace.comin the Data field - Save your changes
This method creates a CNAME record that points your subdomain to Squarespace's servers.
Common Issues and Solutions
Can't find Domain Forwarding Rules?
Your domain connection method determines which options you see. If domain forwarding isn't available, use the manual DNS method above.
Subdomain not working after setup?
DNS changes can take up to 24 hours to propagate. Check your settings are correct and wait a bit longer.
Want to point to a specific page?
Use the forwarding rules to direct your subdomain to any page on your site or even external websites.
FAQs
Can I set a subdomain as my main website address?
No, Squarespace doesn't allow subdomains that share billing and permissions to be set as the primary domain.
How do I direct my subdomain to a specific page?
Set up forwarding rules in the Domain Forwarding section to point your subdomain to any page or external site.
What if I can't find the domain forwarding option?
You'll need to add the subdomain manually using DNS records in your domain's DNS settings.
