Set up a custom domain

Important: If you use CAA Records on your custom domain, you must add a record for letsencrypt.org. If you don’t, Blogger won't create or renew your SSL certificate.

To personalize your blog’s website address, you can buy a domain. If you’re an administrator, you can manage domains registered through Blogger.

Set up your domain with your blog

When you buy a domain from a domain provider, you can set up your domain and manage its settings in Blogger.

 Important: It may take up to 24 hours for your “blogspot.com” address to redirect you to your custom domain.

Set up your domain in Blogger

  1. Sign in to Blogger.
  2. At the top left, select a blog.
  3. In the left menu, click Settings.
  4. Under “Publishing,” click Custom domain.
    1. Enter the URL of the domain that you bought.
    2. Click Save.
  5. You get an error with 2 CNAMEs:
    • Blog CNAME: For name, enter the name as the subdomain, like "blog." or "www." For destination, enter “ghs.google.com.”
    • Security CNAME: “Name: XXX, Destination: XXX.” This is different for each person and is specific to your blog and your Google Account.

Set up your domain provider settings

  1. Go to your domain provider’s website.
  2. Find the Domain Name System (DNS) in the control panel.
    1. Under "Name, Label or Host," enter the subdomain from step 5 above.
    2. Under "Destination, Target or Points to," enter "ghs.google.com."
  3. Enter details for the second CNAME, which are specific to your blog and Google Account.
  4. To activate your DNS settings, wait at least one hour.
  5. Repeat Set up your domain in Blogger.

Redirect URL without subdomain to your blog’s URL

To redirect your readers from “mydomain.com” to “www.mydomain.com,” set up a naked redirect:

  1. Go to your domain provider’s website.
  2. Open your DNS settings.
  3. Add these 4 A-records that point to Google IPs. If A-records for "mydomain.com" already exist, you should remove the existing A-records.
    • 216.239.32.21
    • 216.239.34.21
    • 216.239.36.21
    • 216.239.38.21
  4. Sign in to Blogger.
  5. In the top left, select a blog.
  6. From the menu on the left, click Settings.
  7. Under "Publishing," turn on Redirect domain (mydomain.com to www.mydomain.com).

Fix issues with custom domain setup

If you have problems, try these steps:

  • When you set up your domain, you may not have to enter the 2 CNAMEs.
  • Make sure the "Name, Label, or Host" CNAME is correct.
  • If your custom domain doesn’t work, wait before you try the steps again. If you have problems, contact your domain provider.
