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.

passKey pages discoveredKey pages crawl

Crawled 12 of 12 discovered pages beyond the homepage.

infoWebsite platformplatform

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

Understanding

Can agents understand your content?

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.

warnDOM size is reasonableStructured data & HTML

Homepage contains ~1958 elements — heavy.

Fix: Aim for under 1500 elements on the homepage. Heavier DOMs slow first paint and overflow some AI crawlers' parse buffers.

warnHeading hierarchy is intactStructured data & HTML

Detected 1 heading level skip (e.g. h1 → h3).

Fix: Tighten the heading order so each level only steps down by one. Skipped levels confuse both screen-readers and AI structural extractors.

warnImages have explicit dimensionsStructured data & HTML

Only 0/98 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.

warnSemantic landmark elementsStructured data & HTML

Missing landmark elements: main.

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

4 of 12 pages are missing <title> and/or <h1>: /diamond-and-jewelry-education, /home-page-new, /james-allen-faq, /the-clear-cut.

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 1089 words of visible text — content is reachable without executing JavaScript.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

passImages have alt textStructured data & HTML

98 of 98 <img> tags have alt attributes.

passInternal links on homepageStructured data & HTML

290 internal links found.

passSingle H1 on homepageStructured data & HTML

Exactly one <h1> on the homepage.

passKey pages are server-renderedKey pages crawl

All 12 pages return ≥80 words of visible text without JavaScript.

Operability

Can agents actually operate the page?

fail`button`, `link`, and `menuitem` elements do not have accessible names.Accessibility

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

Fix: Give ARIA buttons/links/menuitems an accessible name.

failButtons do not have an accessible nameAccessibility

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

Fix: Give every <button> discernible text or an aria-label so agents can identify it.

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.

warnAccessibility tree is agent-navigableAccessibility

2 of 11 agent-critical accessibility audits failed (Buttons do not have an accessible name, `button`, `link`, and `menuitem` elements do not have accessible names.) — 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).

warnOverall accessibility scoreAccessibility

Lighthouse accessibility score: 87/100. 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.

warnForms use autocomplete attributesStructured data & HTML

No autocomplete attributes on any data-collecting form field.

Fix: Add autocomplete hints (email, tel, name, etc.) so form-filling agents and browsers can populate fields without guessing.

warnForm errors are accessibleStructured data & HTML

0/1 data-collecting forms expose errors via ARIA attributes.

Fix: Wire inputs to their error containers with `aria-describedby` and toggle `aria-invalid` on validation failure. Agents that can't see styled error text rely on these attributes.

warnCumulative Layout ShiftPerformance

0.110 (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.

warnTime to First BytePerformance

1.55s (field data from CrUX) — needs improvement.

Fix: Every request an AI agent makes pays this server latency, and agents make many requests per task. Reduce TTFB with edge caching, a CDN, and shipping less server-side work per request.

passForm fields publish validation hintsStructured data & HTML

All 1 data-collecting forms include pattern/min/max constraints.

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.

warnContent-Security-Policy headerSecurity & trust

No Content-Security-Policy header on the homepage.

Fix: Add a Content-Security-Policy. Even a strict default-src directive cuts XSS blast radius dramatically. Start in report-only mode to find violations.

warnHTTP Strict-Transport-Security headerSecurity & trust

HSTS max-age=15552000 is below six months.

Fix: Raise max-age to at least 15768000 (six months). The HSTS preload list requires 31536000 (one year).

warnhttp:// redirects to https://Security & trust

http://bluenile.com did not respond: fetch failed.

Fix: Listen on port 80 and 301-redirect every request to the https:// origin.
