Step 3: Add First CNAME Record

Create a CNAME record with:

  • Host: [unique verification code from Squarespace]

  • Data: verify.squarespace.com
  • TTL: 2 hours

Step 4: Add Second CNAME Record

Create another CNAME record with:

Verification:

The domain is properly linked when it appears in your Squarespace Domains panel with a "Linked" status.
