What does this mean?
It means automatically redirecting http://domain-name.com to http://www.domain-name.com.
There are many benefits of redirecting traffic from non-www to www.
The main advantage is, it will avoid duplicate content in search engines like Google and Bing. It will also give a consistency to your website.
So how to implement this?
Just copy paste the below three lines in your .htaccess file.
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
Now your non-www traffic is redirected to www traffic.
