Congratulations, You're reading this article probably because you bought a new domain for your blog. Using a custom domain is the best investment you can do. So in this tutorial we'll explain how to setup your custom domain on blogger.
Go To Blogger > Settings > Publishing > Click on Add a custom domain
Click on Switch to advanced settings
Now click on settings instructions
Now choose your domain type. We will use top-level domain
Now after above step this below part will appear...now you have to copy highlighted part from it. Please note that these two codes are different for every blog. So grab your own code from that page.
Now go to your domain provider (for example BigRock). And locate your DNS (Domain Name System) settings. Now choose CNAME records.
Add two CNAME records. In Host, Label or Name enter www and in Destination, Target or Points enter ghs.google.com just like showns below:
In second CNAME enter first yellow code as Host Name and second long yellow code as Destination, Target or Points.
Now again Go To Blogger > Settings > Publishing > Click on Add a custom domain > Click on Switch to advanced settings > Enter your domain and click on save.
It's done....After this we will setup A-Records for Naked Domain Redirection (Using your domain without www. )
