Enhance your brand by creating a subdomain for your blog or store.

If you have a Squarespace-managed domain or third-party domain connected to Squarespace via Nameserver Connect, follow this guide to set up a subdomain. If you want to use a third-party subdomain, visit Connecting a third-party subdomain to your Squarespace site.

What is a subdomain?

A subdomain is an extension of the “root” domain name that forwards to your site. The most common subdomain is "www," as in www.yourdomain.com, where “yourdomain.com” is the root domain.

While "www" will always point to your primary domain, you can create custom subdomains that point to the same domain, or point elsewhere. One example would be a domain like “blog.yourdomain.com,” where the subdomain is "blog." Your subdomain is the part that replaces the standard “www” and goes in front of your root domain.

Note: Subdomains of Squarespace-hosted domains that share billing and permission settings with a website can't be set as the primary domain for that website. 

Where will a subdomain point?

The steps in this guide explain how to point your subdomain to where the root domain connects. Usually that's your site's homepage. For example, the subdomain blog.yourdomain.net directs to the root domain www.yourdomain.net.

If you're directing your subdomain to another page or site, follow our steps for forwarding a subdomain or pointing a subdomain instead. We recommend reviewing the difference between forwarding and pointing first. 

Create a subdomain

To create a subdomain for your Squarespace domain:

1. Open your domains dashboard.
2. Click the domain you're editing.
3. Click Website.
4. Scroll down to Domain Forwarding Rules, and click Add rule.
5. In the Forward from, enter the name of the subdomain, such as blog.
6. In the Forward to field, enter your root domain. It should look something like yourdomain.com.
7. Under Advanced settings, select if this move will be a Temporary Redirect (302) or a Permanent Redirect (301).
8. Under Forwarding over SSL, we recommend keeping SSL On selected.
9. Click Save.

Tip: If you’re not seeing the option to add a domain forwarding rule, review our steps below to manually add the subdomain.

Edit a subdomain

To edit your subdomain:

1. Open your domains dashboard.
2. Click the domain you're editing.
3. Click Website.
4. Scroll down to Domain Forwarding Rules.
5. Click Edit next to the subdomain, and make your changes.
6. Click Save.

Delete a subdomain

To delete your subdomain:

1. Open your domains dashboard.
2. Click the domain you're editing.
3. Click Website.
4. Scroll down to Domain Forwarding Rules.
5. Click the red trash can next to the subdomain.
6. Click Confirm in the pop-up window.

Manually add a subdomain

If Domain Forwarding doesn't appear in your Domain Overview panel, your domain is using either Nameserver Connect or DNS Connect to connect to your Squarespace site.

If you’re using DNS Connect, you can connect your third-party subdomain to your Squarespace site using DNS records.

If you're using Nameserver Connect, you can create a subdomain manually by adding a DNS record to your domain:

1. Open your domains dashboard.
2. Click the domain you're editing.
3. Click DNS.
4. Scroll down to Custom Records and click Add record.
5. In the Host field, enter your subdomain. For example, if the full subdomain you want is “blog.yourdomain.com,” you’d enter blog
6. In the Data field, enter ext-sq.squarespace.com
7. Click Save.
