Discoverability

Can agents find your site and its capabilities?

failWebMCP / agent-protocol tools discoveredAgent manifests

The page registers no tools via the WebMCP browser API (navigator.modelContext).

Fix: Expose your actions to AI agents with the WebMCP browser API: register tools via navigator.modelContext.registerTool. Optionally also publish a /.well-known/webmcp.json tool catalog as a discovery signpost.

pass/llms.txt guide for AI agentsAgent manifests

Found https://webex.com/llms.txt.

pass/llms.txt lists key pages as markdown linksAgent manifests

Found at least one "[name](url)" markdown link.

pass/llms.txt has a summary blockquoteAgent manifests

Found a "> summary" blockquote.

pass/llms.txt opens with an H1 titleAgent manifests

First line is a top-level "# Title" heading.

passKey pages discoveredKey pages crawl

Crawled 3 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?

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.

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.

warnImages have alt textStructured data & HTML

75 of 78 images have alt attributes (96%).

Fix: Add alt text to the remaining images. Empty alt="" is fine for purely-decorative graphics.

warnImages have explicit dimensionsStructured data & HTML

Only 1/78 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.

warnSingle H1 on homepageStructured data & HTML

Found 2 <h1> tags. Most AI summarisers expect exactly one.

Fix: Demote the secondary H1s to H2 — keep H1 reserved for the page title.

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

1 of 3 pages are missing <title> and/or <h1>: /products.

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.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 1410 words of visible text — content is reachable without executing JavaScript.

passDOM size is reasonableStructured data & HTML

Homepage contains ~1051 elements.

passHeading hierarchy is intactStructured data & HTML

13 headings, no level skips.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

passInternal links on homepageStructured data & HTML

14 internal links found.

passKey pages are server-renderedKey pages crawl

All 3 pages return ≥80 words of visible text without JavaScript.

Operability

Can agents actually operate the page?

failAccessibility tree is agent-navigableAccessibility

3 of 14 agent-critical accessibility audits failed (`[role]`s do not have all required `[aria-*]` attributes, `[aria-*]` attributes do not match their roles, Elements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children.) — an agent may be unable to identify or operate the affected elements.

Fix: Fix the failing agent-accessibility audits listed below (accessible names on controls, valid ARIA roles/relationships, nothing interactive hidden from the tree).

fail`[aria-*]` attributes do not match their rolesAccessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Remove ARIA attributes that aren't allowed on the element's role.

fail`[role]`s do not have all required `[aria-*]` attributesAccessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Add the ARIA attributes each role requires.

failElements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children.Accessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Ensure ARIA roles that need specific children contain them (e.g. list → listitem).

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.

failCumulative Layout ShiftLighthouse Agentic

0.355

failWebMCP tools registered with the browserWebMCP tools

The page registers no tools via the navigator.modelContext browser API, so an AI agent has no structured way to operate it.

Fix: Expose your site’s actions to AI agents with the WebMCP browser API: call navigator.modelContext.registerTool({ name, description, inputSchema, execute }) from your page so an agent can invoke them. Implement it directly, or with a library like the @mcp-b polyfill (https://mcp-b.ai). Spec: https://github.com/webmachinelearning/webmcp.

warnOverall accessibility scoreAccessibility

Lighthouse accessibility score: 78/100. Agents read the page through its accessibility tree, so this is a proxy for how navigable your site is to an AI agent.

Fix: Resolve the failing accessibility audits below — each one removes an element or relationship an agent would otherwise be blind to.

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?

failNo mixed-content referencesSecurity & trust

Found 1 http:// reference in the homepage HTML — browsers will block these resources.

Fix: Update every http:// resource URL to https:// (or use protocol-relative `//`). Common offenders: image CDNs and legacy embed snippets.

warnOAuth authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returned 500.

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 500.

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.

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.
