Step#1 - Buy Your Domain Name
Well, you must have your own domain name to assign it with your blogspot blog. It does not cost much, you can easily purchase a gTLD domain (i.e. .com, .net, .org etc) for $7-$8 only. There are so many domain registrars providing domain registration services. However you can purchase domain name directly from your blogger account too but you are suggested to purchase domain either from Godaddy.com or from Name.com. Their prices are reasonable and they also give additional discounts on purchase. Must check Godaddy coupons and Name.com coupons.
Step#2 - Setup Domain using DNS setting
DNS stands for Domain Name System. A DNS is used to point domain name to desired IP locations and its necessary to point your domain DNS to your blogger blog. All domain registrars have easy DNS setting panels. You are not required to buy webhosting or to set custom nameservers. Following are the settings you must enter in your Domain DNS.
- Login in Your Name.com account
- Click on "My Account" then on Your Domain Name and then click on DNS Record Management option.
- Now remove all existing records and add following records (as shown in below image)

- Thats it, Step#2 is complete
