SSL Certificate What is an SSL Certificate? SSL stands for Secure Sockets Layer . It's a digital certificate that authenticates a website's identity and enables an encrypted connection .
Why SSL is Important Security : Encrypts data transferred between the user's browser and the web server. Trust : Displays a padlock icon and HTTPS in the browser’s address bar, assuring users of the website's security. SEO Benefits : Google favors HTTPS websites in search rankings.
