Learn how to link an external subdomain to your Squarespace site with these simple steps.

A subdomain (like blog.yourdomain.com) extends your domain name to direct traffic to specific parts of your site. Here's how to set it up:

Prerequisites:

• A registered domain name
• Access to your domain provider's DNS settings
• Your Squarespace site

Step 1: Connect in Squarespace

1. Go to Settings > Domains
2. Click "Use My Domain"
3. Enter your subdomain name
4. Click "Connect From Provider"
5. Select "Other" from the dropdown
6. Click "Connect Domain"
7. Keep the DNS Settings panel open

Step 2: Add First CNAME Record

• Host: [Copy unique validation code from Squarespace]
• Type: CNAME
• Points to: verify.squarespace.com

Step 3: Add Second CNAME Record

• Host: [Your subdomain]
• Type: CNAME
• Points to: ext-cust.squarespace.com

Step 4: Complete Setup

1. Return to Squarespace
2. Click "Update Records"
3. Wait 24-72 hours for changes to take effect
4. Verify connection in Domains panel

If Using as Primary Domain:

1. Open Domains panel
2. Click on subdomain
3. Uncheck "Use www prefix"

Troubleshooting Tips:

• If CNAME records aren't supported, use TXT records instead
• Remove any conflicting A-Records
• Ensure proper formatting of DNS records
• Allow up to 72 hours for propagation

Note: You don't need to connect your main domain before connecting a subdomain. The www CNAME will show as "Record Not Found" even after successful connection.
