Definition
HTTPS (Hypertext Transfer Protocol Secure) is an extension of the Hypertext Transfer Protocol (HTTP) designed to secure communications over a network. It utilizes Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL), to encrypt the data exchanged between web clients and servers, ensuring confidentiality, integrity, and authenticity.
User Cases
In real-world scenarios, HTTPS is widely used for secure online transactions, such as e-commerce and online banking, where sensitive data like credit card numbers and personal information are transmitted. It is also essential for securing user login credentials on websites and protecting communications in APIs and web applications.
Why It Matters for SEO
HTTPS is crucial for SEO as search engines like Google prioritize secure websites in their rankings. Sites using HTTPS are more likely to rank higher in search results, as it signals trustworthiness and security to both users and search engines. Additionally, browsers often warn users about non-HTTPS sites, potentially reducing traffic to unsecured websites.
