You can add a favicon by following these steps:
- Create a “favicon.ico” file from your preferred image. You can either use an image editing tool—such as Adobe Photoshop, GIMP, MS Paint, etc., or you can use this website: http://www.favicon.cc/.
- Upload the image to your “web root” for your website. If this is your primary domain, the directory is “/public_html/”. If it is for a subdomain or addon domain, please refer to your cPanel → Domains → Subdomains or cPanel → Domain Manager section to see what directory the domain is assigned to.
- Clear your browser cache, then visit your website again.
