What is the HTTPS protocol and why it matters

This article explains what HTTPS is and its role in securing web traffic and network operations. When you load a site in a browser, data exchange is handled by specific protocols. You may see HTTP in URLs, but what about HTTPS? How does it differ from HTTP, and what are its advantages and drawbacks? Here we cover these questions.

What is HTTPS?

HTTPS is the secure version of HTTP that uses TLS or SSL to encrypt the connection and protect exchanged content from unauthorized access or alteration.

What is HTTP?

HTTP is the most common protocol for browser–server communication, transferring data in plaintext. HTTPS adds encryption to provide security.

Benefits and drawbacks of HTTPS

Benefits include privacy, data integrity, user trust, support for modern browser features, and improved SEO. Drawbacks typically relate to certificate costs and the complexity of configuration, though free certificates and ongoing improvements reduce these barriers.

Differences between HTTPS and HTTP

HTTPS encrypts all data between client and server, preventing tampering or eavesdropping. HTTP does not. HTTPS is common for banks, portals and online transactions, and is now also used to improve user experience and SEO. In terms of speed, with proper configuration TLS/HTTP‑2 HTTPS can be as fast or faster than HTTP.

How to move from HTTP to HTTPS

1. Obtain a valid SSL/TLS certificate (free options exist).
2. Configure your server/host with SSL/TLS.
3. Update internal and external links to HTTPS.
4. Set up 301 redirects from HTTP to HTTPS or use HSTS.
5. Update SSL settings in CDN.
6. Submit the updated site to search consoles and analytics.

Impact of HTTPS on SEO and rankings

Security of websites matters not only for protecting users but also for improving ranking in search engines. HTTPS plays a key role in increasing user trust and improving SEO. This section examines the impact of HTTPS on rankings.

Studies indicate a large share of first page results use HTTPS.

1. HTTPS as a Google ranking factor

Since 2014, Google has stated that HTTPS is a ranking signal. Sites using HTTPS tend to rank higher than those using HTTP. When content is comparable, Google may prefer the HTTPS site. Several studies show a large portion of first-page results use HTTPS.

2. Increased CTR and reduced bounce rate with HTTPS

Users feel more secure seeing the padlock and secure indicators; HTTP sites may show Not Secure in modern browsers, which can reduce trust and click-through rates.

1. Users entering data on secure sites tend to enter information more readily.
2. The Not Secure message on HTTP may deter further browsing.
3. HTTPS can boost user trust and dwell time, a positive signal for SEO.

3. Preventing security issues and SEO impact

HTTPS encrypts user data and prevents man-in-the-middle attacks. It reduces the risk of being flagged as deceptive or unsafe by search engines and helps prevent content tampering by intermediaries.
