Hypertext Transfer Protocol Secure (HTTPS)
Hypertext Transfer Protocol Secure (HTTPS) is the encrypted version of HTTP, the protocol browsers use to load web pages. It uses TLS certificates to encrypt data between a visitor and a server and to verify the site's identity. Browsers mark non-HTTPS pages as not secure, and Google treats HTTPS as a lightweight ranking signal.

Why Hypertext Transfer Protocol Secure Matters
HTTPS protects form submissions, logins, and payments from interception, and it prevents tampering with page content in transit.
Visitors see warnings on insecure pages, which can reduce trust and enquiries. It is also a baseline expectation of technical SEO.
How It Works
A certificate is installed on the server, often automatically by the website hosting provider. The browser and server then negotiate an encrypted connection before exchanging data.
Every HTTP address should permanently redirect to its HTTPS version, and internal links, images, and the canonical URL should use HTTPS to avoid mixed-content warnings.
Hypertext Transfer Protocol Secure Example
Hypothetical example: a contractor's older site still loads images over HTTP, so browsers show a warning on the quote form. Updating image links and redirecting HTTP addresses removes the warning.
HTTPS vs. HTTP
HTTP sends data in plain text, while HTTPS encrypts it. Modern sites should serve every page over HTTPS.
Common Mistakes
A common mistake is installing a certificate but leaving HTTP pages accessible or linking to insecure assets.
Putting It Into Practice
Confirm the certificate renews automatically, all pages redirect to HTTPS, and sitemaps list HTTPS addresses.
Check for mixed-content warnings after site changes. Explore AI website packages that include hosting with HTTPS.
Frequently Asked Questions

SSL is the older name for the encryption; modern HTTPS uses TLS.
