How HTTPS encrypts web traffic using TLS to protect data in transit.

HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP. It encrypts the connection between the browser and server using SSL/TLS, protecting data from interception and tampering.

Why it matters: HTTPS is a confirmed Google ranking signal, protects user data, and is required for modern browser features like service workers and geolocation. Browsers mark non-HTTPS sites as "Not Secure".

Quick tips:

  • Redirect all HTTP traffic to HTTPS with a 301 redirect.
  • Enable HSTS to prevent downgrade attacks.
  • Ensure all page resources (images, scripts) load over HTTPS to avoid mixed content warnings.
