We have obviously heard about Blogger. It is a weblog publishing tool of Google. Most of the Professional bloggers in the world use wordpress installed in a Host server and link a domain ( .com, .net, .org etc) with it. But those who use Blogger platform for publishing their blog post use their blogging id prefixed with the Blogger domain (i.e xyz.blogspot.com). If you want to link a domain of your own with blogger then you need to follow certain steps for the needed setup. As an example, I am selecting GoDaddy Domain Registrar and a .com domain namely, mybloggingdomain.com. The reason behind the selection is Godaddy.com is world's number 1 domain registrar and .com is the most popular and commercially accepted top level domain extension.Assuming that you have already purchased a .com domain from godaddy.com, following are the steps for linking a custom domain with your blogger blog:
i) login to your Godaddy account and navigate to MyAccount Section.
ii) Select the Domain which you want to link with blogger. You will get a page like the following:-
iv) If you scroll down the page frame you will get "DNS Manager". Launch the DNS Manager.
v) You need to add 4 "A" entries with IPs 18.104.22.168, 22.214.171.124, 126.96.36.199 and 188.8.131.52 as shown in the Screenshot.
vi) Under CNAME Section add the Google Server :- ghs.google.com for www subdomain.
vii) Now, login to your Blogger account and navigate to "settings ---> publishing". Here, you enter the informations regarding your custom domain.
Don't forget to check the option "redirect mybloggingdomain.com to www.mybloggingdomain.com"
Wait for maximum 1 Hour for the settings to take effect. Sometimes it reflects in 5-10 mins.
