HTTPS
HTTPS (Hypertext Transfer Protocol Secure) is the encrypted version of HTTP, the protocol used to transfer data between a web browser and a website. HTTPS uses TLS (Transport Layer Security) encryption to protect data in transit, ensuring that sensitive information like login credentials, payment details, and personal data cannot be intercepted or tampered with. It is the standard protocol for all websites, not just those handling financial transactions.
How HTTPS Works
When a user connects to an HTTPS-enabled website, a TLS handshake occurs between the browser and the server. The server presents its SSL/TLS certificate, which the browser verifies against trusted certificate authorities. Once verified, an encrypted connection is established using symmetric encryption keys. All data exchanged during the session is encrypted, making it unreadable to anyone intercepting the traffic. This entire process happens in milliseconds and is invisible to the user.
Why HTTPS Matters
HTTPS is a confirmed Google ranking factor, and browsers like Chrome display “Not Secure” warnings for sites still using HTTP. Beyond SEO, HTTPS is essential for user trust. Visitors are unlikely to submit forms, enter payment information, or create accounts on a site without the padlock icon in the address bar. HTTPS also prevents man-in-the-middle attacks, where malicious actors intercept or modify data between the user and the server. For businesses evaluating website builder software or web hosting services, built-in HTTPS support should be a baseline requirement.
Implementing HTTPS
Migrating from HTTP to HTTPS requires obtaining an SSL/TLS certificate, installing it on your web server, and redirecting all HTTP traffic to HTTPS using 301 redirects. Free certificates from Let’s Encrypt have made HTTPS accessible to every website. Most modern hosting providers and CDNs include automatic HTTPS provisioning and certificate renewal. After migration, update all internal links, canonical tags, sitemaps, and third-party integrations to use HTTPS URLs to avoid mixed content warnings.
HTTPS and Performance
Contrary to early concerns, HTTPS does not meaningfully slow down modern websites. HTTP/2, which requires HTTPS in most browsers, actually improves performance through multiplexing, header compression, and server push. Sites using HTTPS with HTTP/2 typically load faster than their HTTP/1.1 counterparts. This makes HTTPS both a security and a performance upgrade.
