AIDE check proto-oauth-discovery — under the protocol category. Learn what it measures, why it matters and how to fix it.

Profiles using this check: ai_ready

Why it matters

Modern AI and search agents reach your site over HTTPS, HTTP/2 or HTTP/3 — compression, cert trust, header correctness and TTFB are their foundation. Old protocols carry direct ranking penalties.

How AIDE tests it

AIDE's scanner inspects your HTML, response headers, and where applicable external signals to evaluate proto-oauth-discovery, then returns PASS / WARNING / FAIL / SKIPPED against the threshold. Weight: 1.0 points, severity: high.

How to fix it

  • Redirect HTTP → HTTPS (301) and add yourself to the HSTS preload list.
  • Enable HTTP/2 and HTTP/3 (QUIC) — default on Cloudflare/Fastly.
  • Brotli compression + correct Cache-Control + ETag.
