Scored by v3 · source-of-truth hashes: score db860d6ac94e · thresholds e94f8b33e500 — verifiable against the canonical scorer.
The 28-day score is the p75 of nightly runs — the stable number to cite. Deterministic metrics (CRR/SSD/TC) show their latest value (they move only when the site changes); timing (TTFUT) and answer-fidelity (AF) are smoothed by 28-day p75 — the same lab-vs-field split Core Web Vitals uses. Synthetic daily measurement, not real-user field data.
An agent is likely to fabricate missing details rather than say “I don’t know”. 0/3 applicable facts come from machine-readable structured data.
Metrics
Token Cost breakdown
Where the page's tokens go (≈2,737 across regions). 65% is non-content — chrome and boilerplate an agent pays for. Add landmark roles (main/nav/header/footer) so agents can skip it.
Final screenshot
Diagnostics
content vs chrome/boilerplate
Fix: Wrap the real content in <main>/<article>, cut repeated nav/boilerplate, and keep the primary content dense and early in the DOM.
agent representation — token decomposition
Fix: Strip repeated nav/header/footer/cookie chrome from the agent-visible output; wrap content in <main>/<article> so the extractor keeps signal and drops boilerplate.

Issues (4)
~ No content-blocking cookie wall medium impact Consent platform: trustarc (verify it doesn't block content)
Business impact A consent wall that hides content until a click is invisible to agents — they cannot click 'Accept'.
What we measured We fingerprint OneTrust, Cookiebot, Usercentrics and similar managers and flag content-blocking ones.
How to fix Use an overlay banner that leaves content in the DOM, not a blocking interstitial.
Spec: https://gdpr.eu/cookies/
~ llms.txt present + valid high impact Found at /.well-known/llms.txt but missing H1/blockquote
Business impact llms.txt is the robots.txt for AI: it tells agents what your site is, what matters, and where to find it. Without it AI guesses — and guessing means inaccurate recommendations and lost visibility.
What we measured We fetch /llms.txt and /.well-known/llms.txt and validate the spec (H1 title + a one-line blockquote summary). We also note /llms-full.txt (your full content as Markdown).
How to fix Create /llms.txt with a short summary + key pages; optionally /llms-full.txt with full content in Markdown.
# Your Site
> One-line description for AI agents.
## Key pages
- /products — catalog
- /pricing — plans
- /docs — documentationSpec: https://llmstxt.org
✗ Structured data (JSON-LD) medium impact No JSON-LD found
Business impact Schema.org JSON-LD tells agents what a page IS (product, article, business) with typed fields (price, rating, hours). Without it agents extract less reliably.
What we measured We parse <script type=application/ld+json>, validate it, and check for populated @type fields.
How to fix Add JSON-LD: Organization/LocalBusiness on the homepage, Product on product pages, Article on posts.
<script type="application/ld+json">{"@context":"https://schema.org","@type":"Organization","name":"Your Co","url":"https://example.com"}</script>Spec: https://schema.org/
~ XML sitemap fresh medium impact Stale (lastmod 2025-12-16T12:00:17.714Z)
Business impact A sitemap is your table of contents for AI crawlers. Without it agents follow homepage links and miss deep pages (products, docs, pricing) — shrinking what they can recommend.
What we measured We fetch /sitemap.xml (and /sitemap_index.xml), confirm valid XML with <loc> entries, and check <lastmod> freshness.
How to fix Generate an XML sitemap of all public pages with current lastmod dates and reference it in robots.txt.
# robots.txt
Sitemap: https://example.com/sitemap.xml
Passed audits (8)
Transport & Trust (SEC 1.0.0)
HTTPS, HSTS, CSP, sniffing, referrer and CORS posture. Diagnostic only — this does not affect the CAV score. A security header does not make a page more legible to an agent, so scoring it would reward a CDN toggle that changes nothing an agent can recover. We measure it and say so.
Per-header findings (6)
| Header | Evidence |
|---|---|
| ✅ HTTPS | served over HTTPS |
| ❌ HSTS | no strict-transport-security header |
| ❌ Content-Security-Policy | no content-security-policy header |
| ❌ X-Content-Type-Options | missing nosniff |
| ⚠️ Referrer-Policy | no referrer-policy header (browser default applies) |
| ➖ CORS exposure | no CORS headers on the document (normal for an HTML page) |

destination — 183 KiB transferred, 50.1% unused (third-party)
googletagmanager.com — 554 KiB, 3 requests, 9 ms main-thread

Third-party impact
64 third-party requests · 1427 KiB (35.9% of transfer) · 48 ms main-thread — code an agent must also fetch/run before your content settles. Fewer, lazier third-parties = faster, cheaper agent reads.

Wasted JavaScript (by bundle)
Transfer-accurate — each bundle's transfer size × its unused %, ranked by wasted bytes (the biggest code-splitting wins). Unused JS also inflates Token Cost (TC).
