¿Por qué importa esto?

HTTP/2 loads multiple files simultaneously over one connection (multiplexing), dramatically reducing load time compared to HTTP/1.1. HTTP/3 (QUIC) is even faster on mobile networks.

¿Cómo se soluciona?

Enable HTTP/2 on your web server (requires HTTPS). Nginx: http2 parameter to the listen directive. Apache: mod_http2 module. Cloudflare supports HTTP/2 and HTTP/3 automatically.

Este check puntúa de 0 a 100. Bajo 50 es un fallo, 50 a 89 un aviso, 90 o más es bueno. Tras cada crawl ve la nota por página en el informe, con una breve explicación.
