To set up a custom domain for your blogspot blog, you need to follow these steps:
- Register a domain name with a domain registrar of your choice, such as Google Domains.
- Log in to Blogger, go to Settings > Publishing > Blog Address. Click on Add a Custom Domain Name.
- Enter your domain name with www prefix, such as www.example.com. Click Save.
- You will see an error message with two CNAME records that you need to add to your domain's DNS settings. Copy these records.
- Log in to your domain registrar's website and find the DNS settings for your domain. Add the two CNAME records that you copied from Blogger.
- Optionally, you can also add four A records to point your naked domain (example.com) to Google's IP addresses: 216.239.32.21, 216.239.34.21, 216.239.36.21, and 216.239.38.21.
- Wait for the DNS changes to propagate, which may take up to 48 hours.
- Go back to Blogger, go to Settings > Publishing > Blog Address and click Save again.
- Your blogspot blog should now be accessible from your custom domain.
