What is HTTPS?
HTTPS stands for Hypertext Transfer Protocol Secure. It is the secure version of HTTP, the protocol used to transfer data between a user’s web browser and a website. HTTPS encrypts the data being exchanged using SSL (Secure Sockets Layer) or TLS (Transport Layer Security), ensuring that the communication remains private and secure.
Websites using HTTPS display a padlock icon in the address bar, signalling to users that their connection is encrypted and safe.
Why HTTPS Matters
HTTPS is crucial for protecting user data and building trust. It is particularly important on websites that handle sensitive information such as passwords, payment details, or personal data.
Benefits of HTTPS include:
- Encryption of data transferred between browser and server
- Protection against eavesdropping and man-in-the-middle attacks
- Improved user trust and security signals
- A confirmed ranking boost in Google’s search algorithm
- Eligibility for certain browser features (e.g. geolocation, service workers)
Without HTTPS, browsers may mark your site as “Not Secure,” which can deter users and hurt credibility.
Example in Use
If a user logs into an eCommerce site over HTTPS, their login credentials are encrypted before being transmitted. This helps prevent hackers from intercepting sensitive data. A secure URL will look like https://www.example.com rather than http://www.example.com.
Most websites obtain HTTPS by installing an SSL certificate through their hosting provider or a service like Let’s Encrypt.
