SSL / HTTPS
The green padlock that protects your visitors' data.
Why this padlock?
The SSL certificate (Secure Sockets Layer) encrypts information circulating between the site and the visitor. This is what makes the padlock and "https" appear in the address bar.
Is it mandatory?
Yes. Without it, Google indicates your site is "Not secure," which drives customers away. It's essential to protect passwords and payments.
