GLOSSARY TERM
What is HTTP/2?
Definition
A major revision of the HTTP protocol introducing multiplexing, header compression, and server push. Faster than HTTP/1.1 for sites with many resources.
Why it Matters for AI Search
HTTP/2 is now near-universal. If your site is still on HTTP/1.1, you're paying a real performance tax — multiple requests get serialized, headers repeat, and connection setup is slower. Most CDNs (Cloudflare, Fastly, Vercel) enable HTTP/2 (and HTTP/3) by default.
