Yes, you can connect a Google Domain to Squarespace. This can be done either by transferring the domain to Squarespace or by connecting the domain while keeping it registered with Google. Below, I'll outline the steps for both methods.

Method 1: Connecting a Google Domain to Squarespace (Without Transferring)

1. Log in to Google Domains:

2. Go to domains.google.com and log in with the Google account that has the domain registration.

3. Access Your Domain Settings:

4. Select the domain you want to connect to Squarespace.

5. Navigate to the "DNS" section in the domain's settings.

6. Set Custom Name Servers (Optional):

7. If prompted, you can set custom name servers. It's typically simpler to use Squarespace's default DNS settings. However, if you want to manage DNS records separately, you might need to enter Squarespace-provided name servers.

8. Updating DNS Records:

9. In Google Domains, find the “Custom resource records” section or similar.

   • Add a CNAME Record: This points your domain to Squarespace’s server.
   • Host: Enter www.
   • Type: Choose CNAME.
   • TTL: Use the default value or set it to 1H or 1D.
   • Data: Enter verify.squarespace.com.
   • Add an A Record: If you intend to use a root domain (naked domain without www).
   • Host: Leave it blank or enter @.
   • Type: Choose A.
   • TTL: Use the default value or set it to 1H or 1D.
   • Data: Add the IP addresses provided by Squarespace, which usually include four distinct IPs.

10. Complete Settings in Squarespace:

11. Log in to your Squarespace account.
12. Go to the Home Menu, then click "Settings," followed by "Domains."
13. Click "Use a Domain I Own."
14. Enter your domain name and click "Continue."
15. Select "Connect Domain," then click "Continue" again.

16. Choose "Google Domains" from the list of providers.

17. Verification and Final Steps:

18. Squarespace will prompt you to visit Google Domains and confirm that the verification record has been added.
19. Once verified, the connection process could take up to 72 hours for changes to propagate, but it often completes much quicker.

Method 2: Transferring a Google Domain to Squarespace

1. Prepare Your Domain for Transfer:
2. Log in to Google Domains.
3. Ensure your domain is unlocked. This can be done in the domain's settings under "Registration" status.

4. Obtain your domain’s auth code. This transfer authorization code can be found in the same place where you unlock the domain.

5. Initiate Transfer on Squarespace:

6. Log in to your Squarespace account.
7. Go to "Settings," then "Domains."
8. Click "Use a Domain I Own," enter your domain, and click "Continue."
9. Select "Transfer to Squarespace."

10. Input the authorization code you obtained from Google Domains.

11. Confirm transfer and payment:

12. Review the transfer details and any applicable fees. Domain transfers to Squarespace usually involve a renewal fee.

13. Complete the payment process to initiate the transfer.

14. Wait for the Transfer to Complete:

15. Domain transfers can take up to a week to complete, though they often happen within a few days.
16. During this period, ensure that your current DNS settings remain intact to avoid service disruptions.

Considerations and Limitations

• Propagation Time: DNS changes can take up to 72 hours to propagate, though they often update sooner. Be patient during this period.
• Domain Privacy: Check whether domain privacy (WHOIS protection) will transfer over or if you need to configure it again.
• Email Services: Ensure that any email services associated with your domain are correctly set up on the new platform to prevent loss of email functionality.
• Cost: Be aware of any potential costs involved with domain transfers or renewal fees on Squarespace.

By following these steps, you can successfully connect or transfer your Google Domain to Squarespace, enhancing your website’s branding and accessibility.
