I should say thanks first for Harsh Agrawal for sharing this video on YouTube. This video explains about how to redirect to your website when the user hits your blogspot.com, for example if the user hits the blog called “balajistirupur.blospot.com” to redirected to your blog “techmaza.org” .
Go to blogger dashboard choose the blog to be redirected to the specific domain, go to settings -> Publishing -> Blog Address -> Add a custom domain . Create Cname record and record (adding IP Address to display site) in your domain cpanel control.
when this all process is done open your blogger dashboard and refresh the redirects process starts and works effectively for redirection between your blog site and domain.
