Connecting a subdomain to your Squarespace site

A subdomain is an extension of your domain name that forwards to your site. The most common subdomain is "www," as in If your domain provider supports alternate subdomains, you can also use a subdomain like, where the subdomain is "blog," to redirect to your site. The process of connecting a domain or subdomain to your site is also called mapping.

Use this guide if you're adding a subdomain to an existing third-party domain. If you registered a domain through Squarespace, or if you transferred a third-party domain to Squarespace, visit Creating a subdomain for your Squarespace Domain instead of following this guide.

Note: All connected subdomains will point to the homepage and lead to your primary domain. It isn't possible to connect a subdomain to a page that isn't your homepage. 

Prima di iniziare

  • You'll need a registered domain to set up a subdomain. You can register a domain with Squarespace, including a free custom domain if you're on the yearly plan. If you prefer to register with a third-party provider, ensure they offer Full DNS services. Examples include GoDaddyNetwork Solutions, or Dotster.
  • Dopo aver registrato un dominio, imposta il sottodominio con il tuo provider. 
  • You don't need to connect your regular domain to your site to connect a subdomain. For example, you should connect by following this guide, but you don't need to connect first.

Step 1 - Avvia la connessione in Squarespace

Per connettere il tuo dominio, inizia dal pannello Domains (Domini):

  1. Nel Menu principale, clicca su Impostazioni, quindi clicca su Domini. Puoi anche premere il tasto ? in qualsiasi pannello per ricercare i domini.
  2. Clicca su Use a Domain I Own (Usa un dominio che già possiedi).
  3. Inserisci il nome del sottodominio che desideri connettere nella casella Domain Name (Nome dominio), quindi clicca su Continue (Continua). 
  4. Clicca su Connect From Provider (Connetti da Provider).
Nota: Se vedi un messaggio che indica che questo dominio è già connesso a un altro sito Squarespace, controlla gli altri tuoi siti Squarespace per trovare a quale è connesso il dominio. Quindi, disconnetti il dominio da tale sito.
  1. Select Other from the drop-down menu.
  2. Clicca su Connect Domain (Connetti Dominio).
Note: Even if your third-party provider is listed in the drop-down menu, you should still select Other. The customized setup feature is for connecting domains, not subdomains.
  1. Nel messaggio visualizzato, clicca su Okay.
  2. Viene visualizzato un nuovo pannello con i record da creare nel tuo account provider. Lascia questo pannello aperto come riferimento.

Step 2 - Accedi al tuo account di dominio

Log into your domain account, and find where you manage your DNS settings. Depending on your provider, this may be called Zone File Settings, Manage Domains, Domain Manager, DNS Manager, or something similar.

Here, you'll create these records so your domain correctly links to your Squarespace site.

Step 3 - Aggiungi il primo Record CNAME

In the first line of your Squarespace DNS Settings, copy the unique code that appears directly below the Host column. The unique code is a random string of numbers and letters that must point to

In your provider's DNS manager, create a CNAME with these values:

  • Alias or Host Name - Paste the unique code from the Domains panel (a random string of numbers and letters). Then add a period (".") at the end (with no spaces), followed by your subdomain. For example, if you're connecting, the format should be:
  • Type or Record Type - CNAME or CNAME Alias
  • Points To -
Note: If you're experiencing issues verifying your domain with a CNAME Record or if your domain provider doesn't support CNAME Records, verify your domain using a TXT Record.
Note: If you don't add this CNAME, or if it's entered incorrectly, the domain will unlink from your site after 15 days. If this happens, you can start over to reconnect the domain.

Step 4 - Aggiungi il secondo Record CNAME

In the second line of your Squarespace DNS Settings, www appears directly below the Host column. This is the normal subdomain used for domains, but you'll point your subdomain to instead.

In your provider's DNS manager, create a CNAME with these values:

  • Alias or Host Name - Your subdomain. For example, if you're connecting, the format should be: blog
  • Type or Record Type - CNAME or CNAME Alias
  • Points to -
Note: Your Domains panel may show A records with "Record not found" in the Current Data column. You can ignore these since subdomains only require CNAME records.

Step 5 - Aggiorna

After changing your records, return to your Squarespace DNS Settings and click Refresh below the records.

The Current Data column in the panel will start to update and show if your records are entered correctly. It can take up to 72 hours for this information to process.

Note: The www CNAME will still display as Record not found, even after the subdomain is connected.

Step 6 - Wait and test

If all records are entered correctly, your subdomain will connect to your site within 24 hours. At times, it can take up to 72 hours. Visit the Domains panel at any time to check your progress.

When the domain is correctly linked, the subdomain will direct to your Squarespace site.

Note: Even if your subdomain directs properly you may not see a Connected label in your subdomain panel. This is normal, as the www prefix isn't recognized for subdomains.

Step 7 - Deseleziona l'uso del prefisso WWW

The final step is to disable the "www" prefix from appearing. This is only required if you've set your subdomain as your primary domain.

In the Home Menu, click Settings, and then click Domains. Select the subdomain, and ensure Use WWW Prefix is unchecked.

Note: Wait until your subdomain is correctly linked to complete this step, or you may see a "WWW Prefix Toggle Failed" error message.

Risoluzione dei problemi con la verifica dei record DNS

If we detect that your records weren’t set up properly, your domain will appear in the Domains panel with the message “Can’t verify domain ownership.”

To troubleshoot, use the DNS checker tool in the Domains panel to see the exact CNAME and A Records to fix with your domain provider. 

Click the domain in the Domains panel, and then click DNS Settings. To learn more, visit Checking your domain mapping records.

Note: While these mapping steps will work for most subdomains, we recommend contacting your domain provider for specific help.
