## Vérifications

### Contenu — 66/100

#### Content Negotiation — 0/100

- **FAIL** Homepage does not serve Markdown via content negotiation
  Got text/html (HTTP 200) for "Accept: text/markdown"
  Serve a Markdown representation of your pages when agents request "Accept: text/markdown". Agents like Claude Code and Cursor ask for it, and Markdown cuts token usage by roughly 80% against HTML. Cloudflare ("Markdown for Agents") and Vercel can enable this without code changes.
  https://axrush.com/guides/content-negotiation#not-supported
- **WARN** No <link rel="alternate" type="text/markdown"> fallback found on the homepage
  If you cannot enable content negotiation, advertise a Markdown version with <link rel="alternate" type="text/markdown" href="/index.md"> so agents can discover it.
  https://axrush.com/guides/content-negotiation#no-alternate

#### Opérabilité par les agents — 100/100

- **PASS** 113/113 interactive elements have an accessible name
- **PASS** 1/1 form controls are labelled
- **PASS** Method note: this reads markup, not a rendered accessibility tree
  Labels attached by script and roles computed at runtime are invisible here, so treat low proportions as a prompt to check the real tree rather than as a count. Every finding is also a plain accessibility defect.

#### Structured Data — 0/100

- **FAIL** No JSON-LD structured data found
  Add a <script type="application/ld+json"> block in your HTML <head> with schema.org structured data describing your site, organization, or person.
  https://axrush.com/guides/structured-data#not-found

#### HTML Rendering — 90/100

- **PASS** Server-rendered content detected (404 words, 2588 chars of visible text)
- **WARN** Low text-to-markup ratio (1.1%)
  Recommended minimum: 5%
  A very low text-to-markup ratio is a typical SPA-shell symptom. Inline more content directly into the HTML response.
  https://axrush.com/guides/html-rendering#low-ratio
- **PASS** Semantic landmarks present (main, article, section, header, footer, nav)
- **PASS** Single <h1> heading: "Where teams and agents Think together."
- **PASS** 58/58 <img> tags have alt attributes

#### SEO Basics — 100/100

- **PASS** <title> length 45 chars: "The AI workspace that works for you. | Notion"
- **PASS** Meta description length 124 chars
- **PASS** Canonical URL: https://www.notion.com/
- **PASS** <html lang="en-us">
- **PASS** UTF-8 charset declared
- **PASS** Viewport meta present: "width=device-width, initial-scale=1"

### Accès — 91/100

#### TLS / HTTPS — 100/100

- **PASS** Site is served over HTTPS
- **PASS** HTTP requests redirect to HTTPS
- **PASS** HSTS max-age=31536000
- **PASS** HSTS includes subdomains
- **PASS** HSTS preload-eligible

#### Agent Access — 95/100

- **WARN** Meta-ExternalAgent is refused by Cloudflare while robots.txt permits it
  status 403
  Blocking it keeps your content out of Meta AI training and indexing. This edge verifies crawlers by IP range or signature, so the refusal may be correct anti-spoofing rather than a policy block. ax-audit sends this user agent from its own network without a Web Bot Auth signature, so an edge that verifies crawlers by IP range or signature will reject the probe while admitting the real crawler. Confirm against your WAF logs before changing any rule.
  https://axrush.com/guides/agent-access#blocked-crawler
- **PASS** Amazonbot blocked at the server — consistent with its robots.txt Disallow
  status 403
- **WARN** Bytespider is refused by Cloudflare while robots.txt permits it
  status 403
  Collects training data for ByteDance models. Compliance with robots.txt is disputed. This edge verifies crawlers by IP range or signature, so the refusal may be correct anti-spoofing rather than a policy block. ax-audit sends this user agent from its own network without a Web Bot Auth signature, so an edge that verifies crawlers by IP range or signature will reject the probe while admitting the real crawler. Confirm against your WAF logs before changing any rule.
  https://axrush.com/guides/agent-access#blocked-crawler
- **WARN** 2 crawler probe(s) could not be settled from outside
  Meta-ExternalAgent, Bytespider
  ax-audit sends this user agent from its own network without a Web Bot Auth signature, so an edge that verifies crawlers by IP range or signature will reject the probe while admitting the real crawler. Confirm against your WAF logs before changing any rule.
  https://axrush.com/guides/agent-access#inconclusive-probe

#### Directives IA — 100/100

- **PASS** Homepage is indexable
- **PASS** No directive restricts how AI assistants may use this page

#### Hygiène HTTP — 70/100

- **WARN** A missing page redirects (301) instead of returning 404
  Location: https://www.notion.so/ax-audit-probe-d9vamtpc
  A redirect on a nonexistent path hides the error. Return 404 or 410 so a client can tell the difference.
  https://axrush.com/guides/http-hygiene#soft-404-redirect
- **WARN** Homepage takes 2 redirects to answer
  301 → https://www.notion.so/
307 → https://www.notion.com/
  Every hop is a round trip the agent pays for, and some clients cap redirects well below a browser. Collapse the chain: point the first URL straight at the final one.
  https://axrush.com/guides/http-hygiene#redirect-chain
- **PASS** HEAD requests are supported
- **PASS** Content-Type: text/html with charset

#### Crawl Efficiency — 70/100

- **PASS** Response compressed with gzip
  Brotli (br) typically compresses text 10–20% smaller — consider enabling it.
- **WARN** No ETag or Last-Modified header — conditional requests unsupported
  Send an ETag or Last-Modified header so crawlers can revalidate with If-None-Match / If-Modified-Since and receive a cheap 304 Not Modified instead of the full body.
  https://axrush.com/guides/crawl-efficiency#no-validators
- **PASS** Homepage size is reasonable (235.4 KB decompressed)
- **WARN** Roughly 647 tokens of content in 60,245 tokens of response (99% markup)
  Estimated at four characters per token.
  An agent pays to receive the markup and then discards it. Serving Markdown on Accept negotiation is the direct fix.
  https://axrush.com/guides/crawl-efficiency#markup-overhead
- **PASS** Homepage responded in 412ms

### Découverte — 76/100

#### LLMs.txt — 85/100

- **PASS** /llms.txt exists
- **PASS** /llms.txt Content-Type OK (text/plain)
- **WARN** Missing H1 heading (first line should start with "# ")
  Add an H1 heading as the first line of your llms.txt file, e.g.: # Your Site Name
  https://axrush.com/guides/llms-txt#missing-h1
- **PASS** Blockquote description present
- **PASS** 7 section heading(s) found
- **PASS** 48 link(s) found
- **WARN** /llms-full.txt not found (optional but recommended)
  Create a /llms-full.txt with expanded content — full documentation, API details, and comprehensive site information for AI agents.
  https://axrush.com/guides/llms-txt#missing-full
- **WARN** No rel="describedby" link to llms.txt
  llms.txt v2 uses this relation so a page can name the file that covers it. Add <link rel="describedby" href="/llms.txt"> or the equivalent Link header, so an agent that landed on a deep page does not have to guess that an index exists.
  https://axrush.com/guides/llms-txt#no-describedby
- **WARN** 3 duplicate link(s) in llms.txt
  Each URL should appear once. Duplicates spend an agent’s budget re-reading what it already has.
  https://axrush.com/guides/llms-txt#duplicate-links
- **PASS** 15 sampled link(s) resolve
- **WARN** 1 sampled link(s) redirect
  https://www.notion.com/ai-connectors → /product/notion-ai-for-work
  Point llms.txt at the final URL. Each redirect is a round trip the agent pays for on every visit.
  https://axrush.com/guides/llms-txt#redirecting-links
- **WARN** No per-page Markdown mirror found
  Tried /index.md and /index.html.md.
  llms.txt v2 documents appending .md to a URL for its Markdown version. The index tells an agent which pages exist; the mirrors are what make reading them cheap.
  https://axrush.com/guides/llms-txt#no-markdown-mirror
- **PASS** Consumer note: llms.txt is read by coding agents, not by search
  Google has stated that Search ignores llms.txt, and adoption studies find most published files are never fetched by an AI search crawler. Claude Code, Cursor and OpenCode do fetch it. Treat it as developer tooling, not as a search-visibility signal.

#### Robots.txt — 70/100

- **PASS** /robots.txt exists
- **WARN** 1/12 core AI crawlers configured
  GPTBot — Blocking it keeps your content out of OpenAI model training. It does not affect ChatGPT search citations.
ClaudeBot — Blocking it keeps your content out of Claude model training.
Meta-ExternalAgent — Blocking it keeps your content out of Meta AI training and indexing.
Google-Extended — Controls Gemini training and grounding in Gemini Apps and Vertex AI. It does NOT remove your site from AI Overviews or AI Mode, which follow Googlebot and the snippet directives.
Applebot-Extended — Opts your content out of Apple foundation-model training without affecting Siri or Spotlight.
Bytespider — Collects training data for ByteDance models. Compliance with robots.txt is disputed.
CCBot — Builds the open Common Crawl corpus that many models train on. Blocking it is the single broadest training opt-out.
OAI-SearchBot — Blocking it removes your site from ChatGPT search answers and citations.
Claude-SearchBot — Blocking it removes your site from the index Claude cites when it searches the web.
PerplexityBot — Blocking it removes your site from Perplexity answers and citations. Not used for model training.
ChatGPT-User — Fetches a page because a ChatGPT user asked for that URL. Blocking it breaks link-following in conversations.
  Add explicit User-agent entries for the missing crawlers with Allow: / for each one.
  https://axrush.com/guides/robots-txt#missing-crawlers
- **WARN** 1 AI crawler(s) explicitly blocked
  Amazonbot
  These crawlers have "Disallow: /" rules. If you want AI agents to access your site, change to "Allow: /" for each blocked crawler.
  https://axrush.com/guides/robots-txt#explicitly-blocked
- **PASS** 1 training crawler(s) blocked — recorded as a deliberate policy choice
  Amazonbot
- **PASS** Sitemap directive present
- **WARN** No Content-Signal directive found (optional)
  Declare how crawlers may use your content after access with the Content Signals Policy, e.g.: Content-Signal: search=yes, ai-train=no. Known signals: search, ai-input, ai-train, plus the optional use=immediate|reference|full. Generate yours at contentsignals.org.
  https://axrush.com/guides/robots-txt#missing-content-signals
- **WARN** 1/57 known AI crawlers have explicit rules
  Add explicit User-agent entries for more AI crawlers to maximize discoverability.
  https://axrush.com/guides/robots-txt#low-coverage

#### Meta Tags — 54/100

- **WARN** No AI meta tags (ai:*) found
  Add AI meta tags to your HTML <head>: <meta name="ai:summary" content="Brief description">, <meta name="ai:content_type" content="website">, <meta name="ai:author" content="Your Name">.
  https://axrush.com/guides/meta-tags#no-ai-meta
- **WARN** No rel="alternate" link to llms.txt in HTML
  Add to your <head>: <link rel="alternate" type="text/plain" href="/llms.txt" title="LLM-optimized content">
  https://axrush.com/guides/meta-tags#no-llms-alternate
- **WARN** No rel="alternate" link to the Agent Card in HTML
  Add to your <head>: <link rel="alternate" type="application/json" href="/.well-known/agent-card.json" title="Agent Card">
  https://axrush.com/guides/meta-tags#no-agent-alternate
- **WARN** No rel="me" identity links found
  Add rel="me" links to verify your identity across platforms: <link rel="me" href="https://github.com/yourname">, <link rel="me" href="https://twitter.com/yourname">.
  https://axrush.com/guides/meta-tags#no-rel-me
- **PASS** OpenGraph required tags present (og:title, og:description, og:url, og:type)
- **PASS** Twitter Card required tags present (twitter:card, twitter:title, twitter:description)

#### Sitemap — 100/100

- **PASS** Sitemap located: https://www.notion.com/sitemap.xml
- **PASS** Content-Type is XML (application/xml)
- **PASS** Sitemap-index references 169 child sitemap(s)
- **PASS** 3/3 sample child sitemap(s) reachable
- **PASS** Sample yielded 274 URL(s) across 3 child(ren)
- **PASS** Newest <lastmod> is recent (17 day(s) ago)

#### HTTP Headers — 70/100

- **FAIL** Missing critical header: X-Content-Type-Options
  Add the X-Content-Type-Options response header to your server configuration. This is a critical security header.
  https://axrush.com/guides/http-headers#missing-critical-header
- **WARN** Only 3/7 security headers present
  Add security headers like Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to your server response.
  https://axrush.com/guides/http-headers#low-security-headers
- **WARN** No Link header for AI discovery (llms.txt, Agent Card)
  Add a Link response header pointing to your AI discovery files: Link: </llms.txt>; rel="alternate"; type="text/plain", </.well-known/agent-card.json>; rel="alternate"; type="application/json"
  https://axrush.com/guides/http-headers#no-link-header
- **WARN** No machine-readable discovery relations beyond llms.txt and the Agent Card
  describedby — llms.txt v2 uses this relation to point a page at the llms.txt that covers it.
api-catalog — RFC 9727: the catalog of APIs this publisher offers.
service-desc — RFC 8631: a machine-readable API description.
service-doc — RFC 8631: human documentation for the API.
ai-catalog — Draft: the AI catalog listing agent cards and MCP server cards.
c2pa-manifest — C2PA 2.4: content provenance for media on the page.
license — RSL and other machine-readable licensing terms.
  Advertise what you publish with Link relations so agents stop guessing paths. Add the ones that apply, for example: Link: </llms.txt>; rel="describedby", </.well-known/api-catalog>; rel="api-catalog". Informational in 3.x: this does not affect your score.
  https://axrush.com/guides/http-headers#discovery-relations

### Protocoles — 19/100

#### Agent Card (A2A) — 0/100

- **FAIL** /.well-known/agent-card.json not found
  Site is agent-facing (an MCP surface (a document at /.well-known/mcp.json)). Also tried the pre-0.3 path /.well-known/agent.json. IANA-registered well-known URI.
  This site offers something an agent could call, but nothing tells an agent what. Publish an A2A Agent Card at /.well-known/agent-card.json. A minimal 1.0 card needs name, description, version, capabilities, supportedInterfaces, defaultInputModes, defaultOutputModes and skills. Spec: https://a2a-protocol.org/latest/specification/
  https://axrush.com/guides/agent-card#not-found

#### OpenAPI Spec — 0/100

- **FAIL** API surface present but no machine-readable description found
  Evidence of an API: navigation into an API or developer area. Checked /.well-known/api-catalog, Link and <link> rel="service-desc", and /.well-known/openapi.json, /openapi.json, /openapi.yaml, /.well-known/openapi.yaml, /api/openapi.json, /v1/openapi.json, /swagger.json, /api-docs, /asyncapi.json, /arazzo.json
  The API exists; nothing describes it in a form an agent can read, so using it requires a human to read your documentation first. Serve an OpenAPI description at /openapi.json and advertise it with Link: </openapi.json>; rel="service-desc". For several APIs, publish an RFC 9727 catalog.
  https://axrush.com/guides/api-discovery#not-found

#### MCP (Model Context Protocol) — 75/100

- **PASS** /.well-known/mcp.json exists
- **WARN** /.well-known/mcp.json is not a specified discovery path
  Legacy path. Never part of the MCP specification. Server cards superseded ad-hoc manifests.
  Publish a server card at <your-mcp-endpoint>/server-card with Content-Type: application/mcp-server-card+json, and reference it from /.well-known/ai-catalog.json. Keep this file until your clients have migrated.
  https://axrush.com/guides/mcp-discovery#legacy-manifest
- **PASS** Valid JSON
- **PASS** Server name: "Notion"
- **PASS** Server description present
- **WARN** No tools array defined
  Add a "tools" array. Each tool should have name, description and inputSchema.
  https://axrush.com/guides/mcp-discovery#no-tools
- **WARN** No resources defined
  Add a "resources" array listing the data your MCP server exposes.
  https://axrush.com/guides/mcp-discovery#no-resources
- **WARN** No protocol version specified
  Add a "protocolVersion" field declaring MCP spec compatibility. Current revision: 2026-07-28.
  https://axrush.com/guides/mcp-discovery#no-version
- **PASS** CORS enabled on MCP endpoint

#### Catalogue IA — 0/100 (informe, ne note pas)

- **WARN** No agent resource catalog found
  Checked robots.txt Agentmap: directive, Link header rel="ai-catalog", <link rel="ai-catalog">, well-known path and /.well-known/ai-catalog.json, /.well-known/ard.json. Both specifications are drafts.
  A catalog is one document listing everything an agent can call here — agent cards, MCP servers, APIs, skills — so a client stops probing four conventions to find out. Worth publishing once you have more than one of those. Informational: both ai-catalog.json and ard.json are still drafts, so this never affects your score.
  https://axrush.com/guides/ai-catalog#not-found

#### Compétences d'agent — 0/100

- **WARN** No Agent Skills published
  Checked /.well-known/agent-skills/index.json, /.well-known/skills/index.json, /skill.md, /SKILL.md. Draft specification — the path may still change. Cloudflare RFC v0.2.0 (2026-03-12). Not registered; a competing shorter path (/.well-known/skills/) also ships.
  This site has documentation, so it has procedures worth teaching. A skill is a SKILL.md an agent installs and follows: setup steps, argument shapes, the mistakes to avoid. Publish one per task at /.well-known/agent-skills/{name}/SKILL.md and list them in /.well-known/agent-skills/index.json.
  https://axrush.com/guides/agent-skills#not-found

#### WebMCP — N/A

- **PASS** No forms and no WebMCP code — nothing here for an agent to invoke as a tool

#### Découverte commerce — N/A

- **PASS** No commerce surface — agentic-commerce discovery does not apply to this site
  No Product or Offer structured data, cart links, or product price tags found.

#### Découverte d'authentification — N/A

- **PASS** Nothing on this site requires authorization — auth discovery does not apply
  No API description, API catalog, MCP server card or commerce profile found.

### Politique — 51/100

#### Security.txt — 100/100

- **PASS** /.well-known/security.txt exists
- **PASS** Required field "Contact" present
- **PASS** Required field "Expires" present
- **PASS** Expires date is in the future (2030-01-01)
- **PASS** 2/5 optional fields present

#### RSL License — 0/100

- **FAIL** No RSL license discovery found
  Checked robots.txt License directive, Link header, and <link rel="license" type="application/rsl+xml">
  Declare machine-readable licensing terms for your content with Really Simple Licensing. Add to robots.txt: License: https://your-site.com/license.xml — then publish the RSL document. See https://rslstandard.org.
  https://axrush.com/guides/rsl#not-found

#### Politique d'usage — 40/100

- **WARN** No machine-readable usage policy declared
  Checked robots.txt Content-Signal and Content-Usage, the Content-Usage and content-signal response headers, an RSL licence, TDMRep, and the noai meta directive.
  State your terms where they can be read without a lawyer. The lowest-effort option is a Content-Signal line in robots.txt: Content-Signal: search=yes, ai-input=yes, ai-train=no. Absence is neutral, not permission — but it also gives you nothing to point at.
