Why SSL Matters

SSL (Secure Sockets Layer) encrypts data sent between your browser and the website.
Sites with HTTPS protect your passwords, payment info, and personal data from eavesdroppers.
Browsers display a padlock icon for HTTPS sites and warn you about HTTP-only sites.
Search engines (Google) rank HTTPS sites higher than HTTP-only sites.
Never enter sensitive information on a site without HTTPS.
