HTTPS (HyperText Transfer Protocol Secure) is the encrypted version of HTTP, the protocol used for transferring web data. HTTPS uses TLS/SSL certificates to encrypt communication, preventing eavesdropping and tampering. Google has used HTTPS as a ranking signal since 2014, and modern browsers mark HTTP-only sites as 'Not Secure'. Some domain extensions like .dev and .app require HTTPS by default.
