Discoverability

Can agents find your site and its capabilities?

Crawled 12 of 12 discovered pages beyond the homepage.

Lighthouse Agentic Browsing audits ran.

infoWebsite platformplatform

Could not identify a known website platform (custom stack or unrecognised).

Understanding

Can agents understand your content?

failImages have alt textStructured data & HTML

Only 0 of 1 images have alt attributes (0%).

Fix: Add alt text to every <img>. Screen readers and AI vision models both rely on it to caption images.

failInternal links on homepageStructured data & HTML

No links found on the homepage.

Fix: Add navigation links so AI crawlers can find the rest of your content. A bare landing page is invisible to anything that doesn't already know where to look.

failSemantic landmark elementsStructured data & HTML

No semantic landmark elements (main, header, footer, nav) detected on the homepage.

Fix: Wrap your page structure in semantic landmarks. AI structural extractors rely on them to separate navigation from content from boilerplate.

failSingle H1 on homepageStructured data & HTML

No <h1> tag found on the homepage.

Fix: Add exactly one <h1> that names the page. AI summarisers use it as the document title.

warnMarkdown content negotiationOpen agent protocols

Homepage ignored Accept: text/markdown and returned HTML.

Fix: Serve a markdown version of high-value pages when the client asks for text/markdown. AI summarisers, chatbots and IDE agents prefer markdown — fewer tokens, no DOM noise.

warnHomepage content is server-renderedCrawlability (Google)

Homepage server response contains only 8 words of visible text. AI agents that don't execute JavaScript may see an empty page.

Fix: Consider pre-rendering or server-rendering the homepage so AI crawlers (which typically don't run JS) can see the content. Frameworks: Next.js (Server Components), Nuxt SSR, Astro, or Vite SSG.

warnImages have explicit dimensionsStructured data & HTML

Only 0/1 images have width+height — large CLS risk.

Fix: Set width and height on every <img> so the browser reserves space before the image loads. A layout that shifts while loading makes an AI agent mis-click the element it targeted.

warnKey pages have <title> and <h1>Key pages crawl

1 of 12 pages are missing <title> and/or <h1>: /.

Fix: Make sure every page sets a unique <title> and exactly one <h1>. The title is how an AI agent confirms it landed on the right page after navigating.

warnKey pages are server-renderedKey pages crawl

1 of 12 pages return <80 words of visible text — agents without JavaScript see an empty page: / (8w).

Fix: Pre-render or server-render these pages so AI crawlers (which usually don't execute JS) can read them. Frameworks: Next.js Server Components, Nuxt SSR, Astro, or build-time prerendering.

passDOM size is reasonableStructured data & HTML

Homepage contains ~62 elements.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

Operability

Can agents actually operate the page?

failAccessibility tree is not well-formedLighthouse Agentic

A well-formed [accessibility tree](http://goo.gle/lighthouse-agentic-a11y) helps AI agents to navigate and interact with the page.

warnCumulative Layout ShiftLighthouse Agentic

0.187

warnCumulative Layout ShiftPerformance

0.120 (field data from CrUX) — needs improvement.

Fix: A layout that shifts while loading makes an AI agent mis-click the element it targeted. Eliminate CLS by setting explicit width/height on images and embeds, avoiding inserted content above existing content, and reserving space for ad slots.

passAccessibility tree is agent-navigableAccessibility

All 16 agent-critical accessibility audits passed — an agent can perceive and operate the page through its accessibility tree.

infoWebMCP form coverageLighthouse Agentic

2 forms missing annotations

infoWebMCP tools registeredLighthouse Agentic

Lists the [WebMCP tools](http://goo.gle/webmcp-docs) registered at the time of analysis.

infoTool catalog signpost publishedWebMCP tools

No tool catalog was found at /.well-known/webmcp.json (or /.well-known/webmcp). The catalog is a community convention, not part of the WebMCP standard, so this does not affect WebMCP presence.

Fix: Consider also publishing a tool catalog at /.well-known/webmcp.json: a JSON document with a "spec" of "webmcp/0.1" and a "tools" array, where each tool declares a name and a clear description. It is a community convention (optional, not part of the WebMCP standard) that lets crawlers and agents discover your tools without executing JavaScript.

Trust & Security

Can agents safely transact?

warnOAuth authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returned 404.

Fix: Publish /.well-known/oauth-authorization-server so AI agents discovering your OAuth setup can negotiate flows automatically. Required if your site offers an authenticated API.

warnOAuth protected-resource metadataOpen agent protocols

/.well-known/oauth-protected-resource returned 404.

Fix: Publish /.well-known/oauth-protected-resource so AI agents discovering your OAuth setup can negotiate flows automatically. Required if your site offers an authenticated API.

warnWeb Bot Auth signature headerOpen agent protocols

No Web Bot Auth signature headers — sites can't verify agent identity.

Fix: Web Bot Auth (IETF HTTP Message Signatures over Signature / Signature-Input) lets you cryptographically verify which agent is hitting you. Several CDNs offer turn-key support; otherwise skip until vendor support matures.

warnHTTP Strict-Transport-Security headerSecurity & trust

HSTS configured (max-age=31536000) but missing includeSubDomains.

Fix: Add `includeSubDomains` so subdomains inherit the policy.

warnReferrer-Policy headerSecurity & trust

No Referrer-Policy header on the homepage.

Fix: Add `Referrer-Policy: strict-origin-when-cross-origin` so outbound links don't leak full URLs (including query strings) to third parties.
