- When adding a custom domain in Blogger setting, currently Blogger does not allow adding a root domain (it is called with a term naked domain there). It means, for example, if your domain is google.com, you can not use google.com, must use www.google.com or blog.google.com, or abc.google.com for blogger.
To verify the domain ownership, Blogger will ask to add 2 CNAME records: (1) for www or blog or abc to ghs.google.com and (2) another unique CNAME record and destination generated by Blogger to your domain DNS records. These values vary, so follow its instructions.
Tip:
1. copy and save those values. They are random values but unique (and fixed values) to your domain. You may need to re-use them again.
Even when your domain is successfully authorized, do not remove the random name and address that Google Blogger had shown.
Just in case you lost it, you can go here to see the history of the verification key:
https://www.google.com/webmasters/verification/details
- If you want to start all over again you can: delete your custom domain in Blogger, Unverify your domain in https://www.google.com/webmasters/verification/details then add your custom domain in Blogger again.
It will generate a new unique CNAME for you again.
- In Cloudflare domain DNS setting set CNAME settings for www or blog or abc, and another CNAME record as asked by Blogger.
To avoid issues in this verification step, do not use via Cloudflare proxy ☁️. Use DNS only directly.
# These values vary, please use the values that Blogger has shown
# For example using www
CNAME www ghs.google.com
CNAME uniqueABCDEFname uuniqueABCDEFname address
To auto-redirect yourdomain.com to www.yourdomain.com, you need to add a few A records for your yourdomain.com and turn on this redirect function.

You may need to wait some time for Blogger to process HTTPS stuff.
