To assign a domain to your blog, first we need to update your domain in blogger settings as shown below. 

Once you update, the domain in the settings, the blogger will display an error below your domain.
We need to update cname's your GoDaddy account.

• Login to your GoDaddy account and click on Manage DNS tab. 

• In DNS ZONE FILE tab you will find use classic DNS Manager. Click on that. 

• Update CNAME's as provided by blogger, as shown below and save ZONE File Editor. It takes some time to reflect the changes.
