Top fixes

failJSON-LD presentStructured data

No JSON-LD blocks found. Add a <script type="application/ld+json"> with a schema.org type for this page.

Fix · Webflow: Add JSON-LD in Page Settings → Custom Code (inside <head>) for the page’s type.

failTime to first bytePerformance

TTFB 2704ms. Slow. Agents time out aggressively.

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

warnllms.txt presentDiscoverability

Found /llms.txt but missing H1 header and markdown links.

Fix · Webflow: Publish /llms.txt at your domain root. Build a spec-compliant one at /tools/llms-txt-generator.

failText-to-markup ratioReadability

Visible text is 2.6% of HTML weight (4681/181687 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%.

warnLink response headersDiscoverability

A Link: header is present but carries none of canonical/alternate/describedby — the relations agents consume.

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

warnHeading hierarchyReadability

Heading issues: 1 skipped level(s).

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