Hi, converting a blog to a custom domain is very easy (because the blogger will take care of the entire hosting procedure itself), but if you buy a domain from GoDaddy or other web hosting services, you need to manually create the settings in the blogger, like this as in your domain administrator. This is a very easy step. Just follow the steps below.

1. Login to your Blogger account -> Settings Tab -> Posting Tab.

2. Click “Switch to custom domain”.

3. Now, click on “Switch to advanced settings”.

4. Enter your domain {Ex: Techzene.com} -> Enter Word Verification and click Save Settings

5. On the next page, check the box [Redirect techzene.com] -> Enter Word Verification -> Save Settings. Now, you will be shown “Congratulations, your blog is ready!”

6. Now, sign in to your GoDaddy account and go to Domains -> My Domains{Domain Manager}.

7. Click your site name and the Open Name Servers link.

8. Enter [NS09. DOMAINCONTROL.COM] for nameserver 1 and [NS10. DOMAINCONTROL.COM] for name server 2. Make sure Custom Name Servers is selected.

9. Now, click on Total DNS Control and MX Records.

10. Delete existing A records, if any (the ones at the top)

11. Click “Add new A record”.

12. Enter the details as shown in the figure below and click OK.

13. Remove the CNAME that has a www Host

14. Click Add New CNAME Record

15. Put www in the Enter an alias name field, ghs.google.com in the Point to host name field, and leave the TTL at 1 hour. Click OK.

NOTE: Settings may take 1 hour to save and work.
