No HTTP/2 or HTTP/3 detected

HTTP/2 and HTTP/3 are modern versions of the protocol that powers web communication. They allow browsers and AI crawlers to load multiple resources simultaneously, making sites significantly faster than older HTTP/1.1 connections. AI crawlers and search engine bots prefer faster, modern protocols and visit HTTP/1.1-only sites less frequently. Slower crawling can delay how quickly new content is discovered and indexed. Contact your web host and ask whether HTTP/2 or HTTP/3 is supported on your plan. Most modern hosting providers enable HTTP/2 by default — in many cases, switching it on is a single setting in your hosting control panel with no changes required to your site.
