No HTTP Link: response headers. Emit canonical/alternate/describedby relations so HEAD-only or stream-rendering agents get them without parsing HTML.

Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.

Visible text is 1.9% of HTML weight (16056/867102 bytes). Low. Markup may be crowding out agent-usable text.

Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.

1 recommended-field warning(s). First: WebSite recommends "potentialAction" (improves agent comprehension).

Fix: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.

Heading issues: 2 skipped level(s).

Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).

TTFB 1775ms. Slow. Agents time out aggressively.

Fix: Agents time out aggressively. Use edge caching for anonymous requests to cut TTFB below 800ms.

No Content-Signal directives. Add e.g. `Content-Signal: ai-train=no, ai-summarize=yes` to declare granular AI usage policy beyond binary allow/disallow.

Fix: Add `Content-Signal:` directives to your robots.txt. This is the emerging standard (Cloudflare-driven) for declaring fine-grained AI usage policy beyond a binary allow/disallow.
