What is HTTP/2 and why does it matter?

HTTP/2 is the major revision of the HTTP protocol that enables multiplexing (loading multiple resources over a single connection), header compression, and server push. It significantly reduces page load times compared to HTTP/1.1.

How do I enable HTTP/2?

HTTP/2 requires HTTPS. Most modern web servers (Nginx, Apache 2.4+) and hosting providers support it. Enable SSL/TLS on your server, and HTTP/2 is usually activated automatically.
