To shift a custom domain to your Blogger blog, follow these steps:
Go to your Blogger dashboard and select the blog for which you want to set up a custom domain.
Click on "Settings" in the left-hand menu and then click on "Basic".
Look for the "Publishing" section and click on the "+ Setup a 3rd party URL for your blog" link.
Enter the custom domain name you want to use for your blog in the text box provided.
Click on the "Save" button. This will display a warning message with the instructions you need to follow.
Go to your domain registrar's website and find the DNS settings for your domain.
Set up a new CNAME record that points to your Blogger blog's address. The address will be in the format of "ghs.google.com" followed by a series of letters and numbers.
Save the DNS settings and wait for them to propagate. This may take up to 24 hours.
Go back to your Blogger dashboard and click on "Save" again. This will link your custom domain to your Blogger blog.
