SSL is short for Secure Socket Layers, and it’s a technology that establishes a secure, encrypted connection for all visitors when viewing a website or submitting information through a website. Websites with SSL certificates are more trusted and increase the credibility of your site.
You probably recognize sites that are secured via SSL by noticing a lock icon on the top of the website. You’ll probably also notice the “https” at the beginning of the domain name, vs. just the standard “http.”
