I have seen most of the good bloggers website and found that some of them are using www and some of them are using non-www.
WWW vs non-WWW – SEO benefits
If I talk with respect to SEO of a website then there is no any benefits of using the www. It is totally an individual choice.
You can choose either www or non-www according to your benefits and interest. I personally don’t use www because I want a shorter length domain.
What’s important is that you stay consistent with the one that you chose at the time of starting your website.
In other words, Don’t change your site URL to add or remove WWW from it..
WWW to non-WWW redirection using .htaccess
You can easily redirect your whole website to non-WWW just by editing your .htaccess file. Insert the below codes in your .htaccess file in between the # BEGIN WordPress and # END WordPress. See the sample below.
# BEGIN WordPress
#Force non-www:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]
# END WordPress
non-WWW to WWW redirection using .htaccess
# BEGIN WordPress
#Force www:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]
# END WordPress
Technical difference between WWW and non-WWW
When you use a domain with WWW, it acts as a hostname which can help with flexibility with DNS, ability to restrict cookies when using multiple subdomains, and more.
Whereas non-WWW domains referred as naked domains and it doesn’t have any technical advantage.
