After purchasing a domain you would prompt to set it up. But after successfully domain setup most of us do a silly mistake that they don’t enable www redirect. As a result when you type your Blog URL with www they Blogger display error page. Many people think that this error evolved from Domain. But in real this is a problem of Blogger.
While we create a Blog on Google Blogger then we get a Google hosted domain that comes with yourdomain.blogspot.com and when we setup a third party domain then we must use that naked Google hosted domain with third party domain (yourdomain.com). In real your Google hosted domain redirects to third-party domain nothing else.
As a result when you type yourdomain.com then it works fine. But when you add www.yourdomain.com then Google Blogger will display an error page, because DNS server can’t recognize your third party domain with www.
As a result we have to solve this issue by enabling non-www to www redirect feature in our Blog. And this is very easy to activate.
Step 1 Log in to your Blogger Account and Go to your Blogger Dashboard
Step 2 Click on -> Settings -> Basic->
Step 3 Now locate Blog Address. Under Third party domain settings click Edit link.
Step 4 And put tick on the check box where written Redirect yourdomain.com to www.yourdomain.com. In your case your purchased domain name will display instead of yourdomain text.
Step 5 Finally click Save button to enable the features.
Now type your domain URL without www (e.g. yourdomain.com) in web browser and see your domain is automatically redirected to (www.yourdomain.com).
That’s it non-www to www Redirect Problem in Blogger now solved. The main benefits of using this redirect is that majority of user while try to enter into a website then they start web address with www. So if you don’t activate this feature then Google will display error page. As a result you will lose big chunk of traffic every day. So I recommend it to enable this feature on your Blogger Blog.
