There are issues on the difference between having “www” ahead of our url/domain of our website ( canonical url ) and without “www” on SEO area. So I am going to show you a simple way of redirecting your domain that has no www or adding www to your domain using CPanel.
1. Login to your cPanel.
2. Navigate to the Domains block of menu.
3. Click Redirects icon inside the Domains bar.
Type: Permanent (301)
redirects to http://www.your-domain.com
Choose “Do not redirect www.
and test it.
Hope that helps.
