Hypertext Transfer Protocol (HTTP)

Hypertext Transfer Protocol (HTTP) is the foundation of data communication on the web, defining how messages are formatted and transmitted between browsers and servers. However, this protocol is now largely outdated and insecure. Modern websites should use HTTPS instead, which adds encryption for security. Using HTTP today can trigger browser warnings, harm user trust, and negatively impact your search rankings as Google strongly prefers secure connections.
