Squarespace

Publish EarlySEO articles to a Squarespace blog using hosted mode with a custom domain.

The Squarespace integration publishes articles to an EarlySEO-hosted blog that you link from your Squarespace site. Squarespace does not provide a public blog-post publishing API, so EarlySEO serves the blog on a custom blog domain such as blog.example.com.

Squarespace stays your main website. EarlySEO hosts the blog content, handles SSL, and gives you a public blog URL to add to your Squarespace navigation.

Prerequisites

A Squarespace site with a connected custom domain, such as example.com
Access to your domain DNS settings
An EarlySEO account

Setup

1. Choose your blog URL

Use a subdomain for the EarlySEO-hosted blog:

blog.example.com

This is the recommended setup. Your Squarespace site remains available at example.com or www.example.com, and the blog lives at blog.example.com.

2. Create the integration in EarlySEO

Go to Integrations in your EarlySEO dashboard
Click Add Integration and select Squarespace
Fill in the form:
- Domain: your root domain, for example example.com
- Mode: choose Subdomain
- Publishing Mode: choose Publish or Draft
Click Create Integration

3. Add the DNS record

In your DNS provider, add this record:

Type:  CNAME
Name:  blog
Value: blog.earlyseo.com

Do not replace your Squarespace root-domain records. Only add or update the blog subdomain record.

EarlySEO automatically registers the blog subdomain with our hosting provider when you create or validate the integration. DNS propagation and SSL provisioning can still take a few minutes.

In Squarespace, add an external navigation link to your hosted blog:

https://blog.example.com

Use a label such as Blog, Articles, or Insights.

Testing

After deploying the integration and DNS record, test in this order.

1. Check DNS

Run a DNS lookup for your blog subdomain:

blog.example.com CNAME blog.earlyseo.com

If you still see another target, wait for DNS propagation or update the DNS record.

2. Check the verification endpoint

Open this URL in a browser:

https://blog.example.com/.well-known/earlyseo-verify

Expected result: a plain text verification token.

If this URL returns 404, the domain is not reaching the EarlySEO hosted-blog app yet.

3. Publish a test article

Create or publish one EarlySEO article for the site. Then open the article URL shown in EarlySEO, for example:

https://blog.example.com/my-test-article

Expected result: the article page loads on the blog subdomain.

4. Revalidate the integration

Return to Integrations in EarlySEO and validate the Squarespace integration. Once the verification endpoint returns the expected token, the integration should show as Connected.

Troubleshooting

Domain not resolving

Verify your DNS records match the values shown in EarlySEO
Make sure the blog subdomain points to blog.earlyseo.com
Use a DNS lookup tool to check propagation status
Wait at least 30 minutes after making DNS changes

Verification endpoint returns 404

Confirm the blog CNAME points to blog.earlyseo.com
Return to EarlySEO and validate the integration so the blog domain can be provisioned automatically
Wait for DNS and SSL provisioning to finish

Cloudflare shows SSL error 525 or Vercel shows DEPLOYMENT_NOT_FOUND

Set the blog record to DNS only while the domain is being provisioned
Confirm the CNAME target is blog.earlyseo.com
Revalidate the integration in EarlySEO
After SSL works directly, Cloudflare proxying can be enabled with SSL mode set to Full (strict)

Articles not appearing

Confirm the integration status shows as Connected in your EarlySEO dashboard
Confirm the article is published, not saved as draft
Open the article URL directly from EarlySEO
Check that your Squarespace navigation link points to https://blog.example.com

SSL / certificate issues

EarlySEO automatically handles SSL for connected domains
If you see certificate warnings, wait for DNS propagation to complete
