SSL Certificate on your site gives you the padlock icon in your browser , and this encrypts communications between visitors to your site and the server. Google is now giving sites without SSL certificates a warning in the browser so it is more important than ever to have an SSL certificate on your site.
All the domain in your cpanell account are automatically enrolled in Auto SSL system – this is included in your cpanel hosting with us.
To force your website to work over SSL you have 2 options. Editing your htaccess and adding the following code:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This will redirect all request / traffic to https version of your website.
Second option
would be installing a SSL plugin and it will only work if you are using a WordPress website. Plugin called Really Simple SSL will do the trick and it is easy to configure.
