Top fixes

failSitemap presentDiscoverability

No reachable sitemap.xml. Publish one and reference it in robots.txt.

Fix: Publish /sitemap.xml and reference it from robots.txt with a Sitemap: line.

failMeta descriptionReadability

No <meta name="description">. Agents use it as a page summary; add a 50–200 character description.

Fix: Add `<meta name="description" content="...">` to your primary pages. Agents frequently use it as a summary.

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: Add a <script type="application/ld+json"> describing the page (Organization, Article, Product, FAQPage).

warnllms.txt presentDiscoverability

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

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

failLink response headersDiscoverability

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.

warnCanonical URLDiscoverability

Canonical points elsewhere: https://iana.org/. Verify intent (cross-domain canonicals are valid but unusual).

Fix: Add <link rel="canonical" href="…"> pointing at the primary URL of each page.
