When you register your blogspot blog, you will get a new blog with some URL like http://yourblogname.blogspot.com . This blog will be hosted on Google’s servers and you can make posts on your blog by logging in at Blogger.Com. Now Custom domain means that we will be using our own domain name instead of having the .blogspot.com extension. That is our blog URL will look something like http://www.yourblogname.com When you use a custom domain, your blog will still be hosted on Google’s servers and you can continue making posts from Blogger.com as you usually do.So the only thing that changes is the blog’s URL
How much does this Cost?
For using a custom domain you should buy your own domain name. The price of the domain name will vary depending on the domain extension that you choose. But normally most of us will prefer to buy domains which ends with a .COM .COM, .ORG , .NET domains will cost something near to10 US Dollars. So you just need to spend 10-12 dollars and you can have your blog running at the new domain which you buy.
Where to Buy the domain from?
There are many domain registration websites. You can directly buy your domain from any of them. If you are in the United States, you can use Google Domains which integrates well with Blogger.
How to buy the domain and setup my blog with the new domain?
If you want to setup your custom domain by buying the domain from Google Domains, then you need to go to Settings > Basic and under the publishing section, you have to choose the Buy a domain option(This is currently only available in the United States as Google Domains is now under Public Beta).
In case Google Domains is still not available in your country, you can easily choose an alternate Domain name provider like Name.com or Godaddy. These are trusted domain name registrars and the domain names will cost somewhere near 10-12 dollars on these websites. You might find some coupon codes on the web which can further reduce the cost. As these are third party registrars, you will have to do some manual configuration to publish your blog to your domain name. This configuration is quite simple and we have tried our best to explain it in detail with descriptive screenshots.
It just costs something less than 10$.. Isn't it worth a try? Hurry up guys ,get your own custom domain blogs and let me know if our tutorials were helpful to you in setting it up :)
