Can agents find your site and its capabilities?
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.
Per llmstxt.org, follow the H1 with a "> short summary" blockquote.
Fix: Add a "> One-sentence description of your site." blockquote under the H1.
Found a Markdown guide at /AGENTS.md.

Found at least one "[name](url)" markdown link.
First line is a top-level "# Title" heading.

Can agents understand your content?
Homepage contains ~2348 elements — heavy.
Fix: Aim for under 1500 elements on the homepage. Heavier DOMs slow first paint and overflow some AI crawlers' parse buffers.
Detected 1 heading level skip (e.g. h2 → h4).
Fix: Tighten the heading order so each level only steps down by one. Skipped levels confuse both screen-readers and AI structural extractors.
Only 4/26 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.
2 of 8 pages are missing <title> and/or <h1>: /pages/customer-services, /pages/about-lloydspharmacy.
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.
Homepage returns text/markdown when requested.
Homepage server response contains 2411 words of visible text — content is reachable without executing JavaScript.
Language declared as "en".
26 of 26 <img> tags have alt attributes.
790 internal links found.
All four landmark elements present (main, header, footer, nav).
Exactly one <h1> on the homepage.
All 8 pages return ≥80 words of visible text without JavaScript.
Can agents actually operate the page?
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.
Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.
Fix: Give every link discernible text (avoid bare icons / "click here") so agents know where it goes.
0.300 (field data from CrUX) — poor.
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.
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.
2 of 14 agent-critical accessibility audits failed (Buttons do not have an accessible name, Links do not have a discernible name) — 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).
Lighthouse accessibility score: 84/100. 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.
`[aria-*]` attributes match their roles passed.
`[aria-hidden="true"]` is not present on the document `<body>` passed.
`[aria-hidden="true"]` elements do not contain focusable descendents passed.
ARIA input fields have accessible names passed.
`[role]`s have all required `[aria-*]` attributes passed.
Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children. passed.
`[role]`s are contained by their required parent element passed.
`[role]` values are valid passed.
ARIA toggle fields have accessible names passed.
`[aria-*]` attributes are valid and not misspelled passed.
`[aria-*]` attributes have valid values passed.
Document has a `<title>` element passed.
671ms (field data from CrUX) — good.
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.
Can agents safely transact?
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.
HSTS max-age=7889238 is below six months.
Fix: Raise max-age to at least 15768000 (six months). The HSTS preload list requires 31536000 (one year).
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.
