## Security

### Security Headers (F — 30/100)

*3 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured (consider adding preload)
- **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
- **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN.
- **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis.
- **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[PASS]** X-Powered-By header is not present
- **[PASS]** Server header is not present
- **[INFO]** Domain is not in the Chrome HSTS preload list (status: unknown) — Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload).

### Content Security Policy (F — 0/100)

*No enforcing CSP policy found*

- **[CRITICAL]** No Content-Security-Policy header found — CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.

### TLS & Certificates (A+ — 100/100)

*TLS 1.3, 7 checks passed*

- **[PASS]** TLS 1.3 is used
- **[PASS]** Strong cipher suite is used
- **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance.
- **[INFO]** OCSP stapling not enabled — Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server.
- **[PASS]** Certificate is valid (expires in 48 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 1 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*No cookies set — no cookie security risks*

- **[PASS]** No cookies set — no cookie security risks

### Cookie Hygiene (A+ — 100/100)

*No cookies set -- cookie-hygiene check is N/A*

- **[PASS]** No cookies set

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

- **[INFO]** No WAF detected — Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva.

### security.txt (B — 70/100)

*Vulnerability disclosure policy*

- **[PASS]** security.txt found
- **[WARNING]** security.txt: Missing required 'Contact' field
- **[WARNING]** security.txt: Missing required 'Expires' field (RFC 9116)

### Cross-Origin Tab Safety (C — 75/100)

*3 of 3 new-tab link(s) missing rel=noopener*

- **[WARNING]** 3 link(s) open in a new tab without rel=noopener — Without rel="noopener", the destination tab can navigate the original tab via window.opener -- a reverse-tabnabbing phishing primitive. Modern browsers default to noopener since Chrome 88 / Firefox 79 / Safari 12.1, but explicit rel="noopener noreferrer" remains the documented best practice for older browsers, in-app webviews, and security scanners.

### CSP Inline-Style Readiness (C — 75/100)

*14 inline style attribute(s) detected*

- **[WARNING]** 14 inline style attribute(s) detected — Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 14 inline style(s) is moderate. Affected element types include: span, div, button, h1, iframe. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win.

### Trusted Types (XSS Sink Hardening) (A+ — 100/100)

*No CSP header -- Trusted Types check is N/A*

- **[PASS]** No CSP header found -- Trusted Types check is N/A

### Bot Challenge Detection (A+ — 100/100)

*Scan reached real page content (no bot-protection interstitial)*

- **[PASS]** No bot-protection interstitial detected -- the rest of the report reflects the real page

### Soft-404 Detection (A+ — 100/100)

*HTTP status is non-2xx -- soft-404 check is N/A*

- **[PASS]** HTTP status is non-2xx -- soft-404 check is N/A

### Empty Page Detection (A+ — 100/100)

*Page has substantive body text and no placeholder / template-leak signals*

- **[PASS]** Page has substantive body text and no placeholder / template-leak signals

### Geo-Restriction Detection (A+ — 100/100)

*No geo-restriction signals detected -- scan reached the page from an allowed region*

- **[PASS]** No geo-restriction detected

### Maintenance Mode Detection (A+ — 100/100)

*No maintenance-mode signals detected -- scan reached a normal page*

- **[PASS]** No maintenance-mode signals detected

### Subresource Integrity Adoption (D — 50/100)

*8% SRI adoption (1/12 third-party resources)*

- **[WARNING]** SRI adoption: 1/12 third-party resources protected (8%) — Of 12 third-party `<script>` / `<link rel=stylesheet>` resources, 1 (8%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource.

Missing SRI on (first 5 examples):
  - https://tracking.stib-mivb.be/gtag/js?id=G-XXXXXXXXXX&cx=c&gtm=4e6562&sign=1fd92f9f02668f40b9073c334228e7fb358c63549317b0f38b5ba30215034376_20260510
  - //www.youtube.com/iframe_api
  - https://www.googletagmanager.com/gtag/js?id=AW-875372945&cx=c&gtm=4e6562&sign=1fd92f9f02668f40b9073c334228e7fb358c63549317b0f38b5ba30215034376_20260510
  - https://connect.facebook.net/en_US/fbevents.js
  - https://www.googletagmanager.com/gtm.js?id=GTM-NR8C6F27&gtg_health=1

Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.

### CORS Depth (A+ — 100/100)

*No CORS response headers -- the resource is same-origin-only by browser default*

- **[PASS]** No CORS response headers -- the resource is same-origin-only by browser default

### Permissions-Policy Granularity (C — 60/100)

*No Permissions-Policy header set -- powerful features (camera / microphone / geolocation / payment / USB) default to allow-on-same-origin*

- **[WARNING]** Permissions-Policy header not set -- features default to allow-on-same-origin — Without a `Permissions-Policy` (or legacy `Feature-Policy`) header, every powerful browser feature defaults to its spec default policy (typically `self`). A third-party iframe injected via XSS or a misconfigured embed can still request access to the user's camera, microphone, geolocation, payment APIs, USB devices, etc. Explicitly deny features the page doesn't need:

```
Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=(), accelerometer=(), gyroscope=()
```

Features the page legitimately uses can stay enabled with `feature=(self)`.

### Referrer-Policy Strictness (B — 75/100)

*Referrer-Policy header not set -- browser default applies (modern: strict-origin-when-cross-origin; legacy browsers: no-referrer-when-downgrade)*

- **[INFO]** Referrer-Policy header not set -- browser default applies — Without an explicit `Referrer-Policy` header, the browser falls back to its default policy. Modern browsers (Chrome 85+, Firefox 87+, Safari 15+) default to `strict-origin-when-cross-origin`, which is privacy-safe. Legacy browsers default to the leaky `no-referrer-when-downgrade`, which sends the full URL (including path + query) on cross-origin HTTPS-to-HTTPS requests. Set an explicit header to ensure consistent behavior:

```
Referrer-Policy: strict-origin-when-cross-origin
```

This matches the modern browser default and is privacy-safe without breaking referrer-based same-origin analytics.

### Source Map Exposure (D — 60/100)

*3 publicly-accessible source map(s) -- full source code leaked*

- **[WARNING]** 3 publicly-accessible JavaScript source map(s) — Source maps (.js.map files) reveal the original source code -- variable names, comments, file structure, and sometimes secrets that were stripped from the bundled output. They're shipped to production by mistake almost universally; the standard fix is a build-tool config flag (Webpack: `devtool: false` or `'hidden-source-map'`; Vite: `build.sourcemap: false`; Next.js: `productionBrowserSourceMaps: false`). Once removed, audit your CDN/edge cache to evict any previously-cached .map URLs. Sample accessible URLs: https://stib-mivb.brussels/modules/stibmivb-template/javascript/main-rrfkY9Wl.js.map, https://stib-mivb.brussels/modules/stibmivb-template/javascript/tracking_NW_2025_16.js.map, https://stib-mivb.brussels/modules/stibmivb-template/javascript/vendors.js.map.

### HTML Version Disclosure (A+ — 100/100)

*No software-version disclosures in HTML*

- **[PASS]** No software-version disclosures in HTML

### Open Redirect Surface (A+ — 100/100)

*No redirect-shaped query parameters in DOM links*

- **[PASS]** No redirect-shaped query parameters in DOM links

### Auth Security (A+ — 100/100)

*Page is not a login form -- auth-security checks are N/A*

- **[PASS]** Page does not appear to be a login form

### Subdomain Inventory Exposure (A+ — 100/100)

*No risky subdomain names in certificate SANs*

- **[PASS]** No risky subdomain names in certificate SANs

- **[WARNING]** External script from consent.cookiebot.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from consentcdn.cookiebot.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from tracking.stib-mivb.be lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from consent.cookiebot.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from kit.fontawesome.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[PASS]** script from cdn.jsdelivr.net has SRI protection

### JS Library Vulnerabilities (A+ — 100/100)

*No known vulnerabilities*

- **[PASS]** No known JavaScript library vulnerabilities detected

### Information Leakage (A+ — 100/100)

*No exposures*

- **[PASS]** security.txt is present — good practice
- **[PASS]** No sensitive files exposed

### Email Security (A+ — 100/100)

*DMARC: reject, SPF: -all, DKIM, MTA-STS: enforce, TLS-RPT*

- **[PASS]** DMARC policy is reject — strongest protection
- **[PASS]** SPF ends in -all (hard fail) — strongest setting
- **[PASS]** DKIM configured (selectors: selector1)
- **[PASS]** MTA-STS in enforce mode - inbound mail protected
- **[PASS]** TLS-RPT configured
- **[INFO]** BIMI not configured — BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.

### API Surface (A+ — 100/100)

*No API specs or GraphQL introspection found (probed 11 candidate path(s))*

- **[PASS]** No API specs or GraphQL introspection found (probed 11 path(s))

### Permissions-Policy (D — 40/100)

*No header set*

- **[WARNING]** No Permissions-Policy header — Consider adding a Permissions-Policy header to restrict browser feature access from embedded content.

### CORS Configuration (B — 80/100)

*No CORS headers*

- **[PASS]** No CORS headers present — secure default

## Performance

### Page Weight Budget (F — 0/100)

*4.8 MB transferred, 83 requests*

- **[CRITICAL]** Page weighs 18.9 MB (4.8 MB transferred)
- **[WARNING]** JavaScript is 3.5 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** Fonts are 307 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[INFO]** 83 HTTP requests
- **[INFO]** Estimated 1.00 g CO2 per page load

### Third-Party Impact (D — 50/100)

*100% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 100% of page weight (4.8 MiB of 4.8 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

### JS Execution Cost (F — 20/100)

*7049ms total JS execution*

- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: 1875ms CPU time
- **[WARNING]** https://www.stib-mivb.be/home: 1228ms CPU time
- **[WARNING]** Unattributable: 1094ms CPU time
- **[WARNING]** https://tracking.stib-mivb.be/gtm.js?id=GTM-NR8C6F...: 618ms CPU time
- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: 546ms CPU time
- **[WARNING]** Third-party scripts: 7049ms (100% of total)

### Font Loading (A+ — 100/100)

*13 fonts (307 KB)*

- **[INFO]** 13 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (F — 0/100)

*23 scripts, 2.9 MB unused*

- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: 681 KB unused (70%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: unminified — 320 KB could be saved
- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: 681 KB unused (70%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: unminified — 320 KB could be saved

- **[WARNING]** https://www.stib-mivb.be/modules/stibmivb-template...: 538 KB unused (49%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://tracking.stib-mivb.be/gtag/js?id=G-XXXXXXX...: 196 KB unused (51%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 2.9 MB

### Resource Caching (A+ — 100/100)

*All resources properly cached*

- **[PASS]** No caching issues found

### Critical Rendering Path (A+ — 100/100)

*No render-blocking resources*

- **[PASS]** No render-blocking resources detected

### Resource Hints (A+ — 100/100)

*No optimization needed*

- **[PASS]** No resource hint issues

### HTTP/3 (QUIC) (B — 75/100)

*HTTP/3 not advertised*

- **[INFO]** HTTP/3 (QUIC) is not advertised — HTTP/3 isn't advertised via Alt-Svc and the worker didn't negotiate h3. HTTP/3 reduces handshake latency (1-RTT instead of 2-3 RTTs) and is more resilient on lossy connections. Most modern CDNs (Cloudflare, Fastly, AWS CloudFront, Google Cloud CDN) support HTTP/3 with a single config switch -- consider enabling for mobile-heavy workloads.

### Compression Algorithm (C — 70/100)

*Main response served uncompressed*

- **[INFO]** Main HTML response has no Content-Encoding (uncompressed) — The main HTML document is served without compression. The Text Compression section above lists the broader picture; for the main response specifically, even gzip would shave ~70-80% off most text payloads.

### LCP Image Preload (A+ — 100/100)

*LCP preload audit not available*

- **[PASS]** LCP image preload audit not available for this scan

### Main HTML Cache-Control (A+ — 100/100)

*Main HTML uses no-cache -- safe revalidate-on-request policy*

- **[PASS]** Main HTML uses no-cache -- safe revalidate-on-request policy

### Server-Timing Observability (B — 85/100)

*No Server-Timing header found*

- **[INFO]** No Server-Timing header found — Server-Timing exposes backend timing breakdowns to browser DevTools (e.g., `db: 45ms; render: 120ms; cache: 2ms`). Useful for diagnosing slow pages without backend log access. Most modern frameworks (Next.js, Cloudflare Workers, Fastly) emit it automatically; absence on a managed platform usually means telemetry headers are stripped at the edge.

### Server Response Intelligence (A+ — 95/100)

*1 server-response signal(s) detected*

- **[INFO]** No `ETag` or `Last-Modified` -- conditional GET not supported — Without either header, browsers can't issue conditional GETs and refresh always re-downloads the full response body even when nothing changed. Add `ETag: "<hash>"` (or `Last-Modified: <date>`) on cacheable responses; the server returns 304 Not Modified when the client's cached copy is still valid, saving bandwidth.

### Page Weight Inventory (F — 15/100)

*83 resources · 4.8 MB · 2.9 MB savings available*

- **[WARNING]** Page weight 4.8 MB exceeds 1 MB target by 3.8 MB
- **[INFO]** ~2.9 MB of savings available
- **[WARNING]** 82 third-party resources (100% of weight)
- **[INFO]** 5 resources over 200KB

### Render-Blocking Resources (A+ — 100/100)

*No render-blocking resources detected*

- **[PASS]** No render-blocking resources detected in <head>

### Third-Party Resources (A+ — 100/100)

*No third-party resources detected*


### JavaScript Blocking (B — 70/100)

*2 JS blocking issue(s) detected*

- **[WARNING]** 8 render-blocking <script src> tag(s) without async/defer — Each `<script src=...>` without `async`, `defer`, or `type="module"` blocks HTML parsing while the browser fetches and executes it. The block lasts the entire round-trip + execution time -- on slow networks this translates directly into LCP delay. Add `defer` (executes after parse, in source order) for scripts that interact with the DOM, or `async` (executes whenever ready) for analytics / independent scripts. Module scripts (`type="module"`) are deferred by default.
- **[WARNING]** Total JS execution time is 7.0 s -- over the 3.5s budget — Total JavaScript execution (parse + compile + run) across all scripts exceeds 3.5 seconds. On low-end devices that becomes 7-15+ seconds and shows up directly in TBT and INP. Reduce by: tree-shaking unused dependencies, code-splitting (dynamic `import()`), removing or deferring third-party tracking, and replacing heavy frameworks where they're not needed.

### CSS Performance Depth (A+ — 100/100)

*No CSS performance depth issues detected*

- **[PASS]** No CSS performance depth issues detected

---

## Content Quality

### Links (A — 90/100)

*87 links checked, 85 healthy, 2 broken*

- **[WARNING]** 85 of 87 links are healthy
- **[WARNING]** Broken link: https://tracking.stib-mivb.be/gtag/js?id=G-XXXXXXXXXX&cx=... — Found in <script src>. Returns HTTP 400.
- **[CRITICAL]** Broken link: https://www.instagram.com/stibmivb?igsh=MXQ5azY2Y21jamt0MA== — Found in <a href>. Returns HTTP 429.

### Mixed Content (A+ — 100/100)

*No mixed content detected — all resources use HTTPS.*

- **[PASS]** No mixed content detected — all resources use HTTPS

### Open Graph (F — 0/100)

*No Open Graph tags found — social sharing previews will be generic.*

- **[WARNING]** No Open Graph meta tags found — Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

### Open Graph / Twitter Card Depth (A+ — 100/100)

*No OG image or Twitter card set -- depth check is N/A (presence covered by Open Graph section)*

- **[PASS]** No OG image / Twitter card to evaluate

### Structured Data (C — 40/100)

*No structured data (JSON-LD) found.*

- **[INFO]** No structured data (JSON-LD) found — Adding structured data helps search engines understand your content and can enable rich results.

### Rich Results Eligibility (C — 75/100)

*No JSON-LD found -- no rich-result eligibility*

- **[INFO]** No JSON-LD structured data on the page — No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

### Image Optimization (F — 35/100)

*5 issues found across 14 images*

- **[WARNING]** 2 images significantly larger than display size — Resizing to display dimensions could save approximately 72 KB.
- **[WARNING]** 14 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 12 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 6 images use legacy formats (JPEG/PNG/GIF) — WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.
- **[WARNING]** 12 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

- **[PASS]** No autoplay media on the page

---

## Infrastructure

### DNS Records (A — 85/100)

*1 A records, 1084 ms lookup*

- **[PASS]** Resolves to 1 IPv4 address(es)
- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[INFO]** No IPv6 (AAAA) records
- **[PASS]** 3 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[WARNING]** DNS resolution is slow (1084 ms) — Slow DNS adds latency to every page load. Consider a faster DNS provider.

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** No CNAME record present

### DNSSEC (B — 80/100)

*Unsigned (DNSSEC not deployed)*

- **[INFO]** DNSSEC is not deployed — The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

### CAA Records (B — 80/100)

*No CAA records (any CA may issue certificates)*

- **[INFO]** No CAA records published — Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

### Reverse DNS (C — 60/100)

*0/1 IPs match cert SAN*

*1 i18n signal(s) detected*

- **[PASS]** Mixed-language content: 2 subtree language(s) declared (fr, nl) — The page has elements with `lang="X"` attributes that differ from the root `<html lang>`. Per WCAG 3.1.2 (Level AA), this is the correct way to mark language-of-parts: a screen reader switches pronunciation when entering a `lang="fr"` block on an English page. The catalog is informational -- presence of subtree lang attributes is a positive a11y signal.

### HTTP Caching (B — 70/100)

*no-cache*

- **[PASS]** Cache-Control header is set
- **[INFO]** No ETag or Last-Modified header — Conditional requests (304 Not Modified) are not possible without validators.

### Operational Status Page (B — 80/100)

*No status page link detected*

- **[INFO]** No operational status page link detected — Status pages communicate planned maintenance and incidents to users -- a hallmark of operationally-mature services. Most SaaS teams publish one via Atlassian Statuspage, Instatus, BetterUptime, or a self-hosted Cachet. Smaller sites legitimately don't need one; flagged as Info, not a failure.

### Transport Security (A — 90/100)

*HTTP/3, HSTS, and TLS version analysis*

- **[INFO]** HTTP/3 (QUIC) not advertised — HTTP/3 eliminates head-of-line blocking. If your CDN supports it, consider enabling it.

- **[PASS]** Public health endpoint at https://stib-mivb.brussels/health

### CDN Cache Observability (B — 85/100)

*No CDN cache-status headers in the response*

- **[INFO]** No CDN cache-status headers in the response — Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.

*Title style is clean -- consistent separator, no stale year, no keyword stuffing*

- **[PASS]** Title style is clean

### Content Depth (F — 25/100)

*245 words, Difficult*

- **[WARNING]** Page has 245 words — thin content — Most well-ranking pages have 300+ words of substantive content.
- **[INFO]** Text-to-HTML ratio is 4% — Very low ratio suggests heavy framework overhead or boilerplate.
- **[INFO]** Reading level: Difficult (grade 14)
- **[WARNING]** Thin content — only 245 words

- **[PASS]** No hreflang tags on the page

### Hreflang Completeness (A+ — 100/100)

*No hreflang tags on this page -- check is N/A (single-language site or unannotated)*

- **[PASS]** No hreflang tags found -- completeness check is N/A

### Sitemap Freshness (C — 70/100)

*Sitemap exists but no <lastmod> entries*

- **[INFO]** Sitemap has no <lastmod> entries — Without lastmod, Google can't tell which URLs have changed since the last crawl -- it falls back to crawling everything periodically. Adding lastmod (date or ISO 8601 timestamp) on each <url> entry signals freshness so the crawler prioritizes recently-modified pages.

### Sitemap × Robots Consistency (A+ — 100/100)

*No sitemap-vs-robots conflicts detected*

- **[PASS]** Sitemap URLs are not blocked by robots.txt

### Sitemap Hygiene (B — 75/100)

*1 hygiene issue(s) on a 0-URL sitemap*

- **[WARNING]** Sitemap is empty -- 0 URLs listed — The sitemap file is reachable and parses as valid XML, but contains no `<url>` entries. Common causes: a templated sitemap that didn't iterate the URL set during build, a static placeholder shipped to production, or a CMS that lost its URL index. Search engines fetch and discard empty sitemaps.

### Markup Quality (A — 92/100)

*1 markup-quality issue(s) detected*

- **[INFO]** `<meta charset>` declared at byte 5307 -- past the 1024-byte spec window — The HTML5 spec requires the encoding declaration to appear in the first 1024 bytes.

## Sustainability

### CO2 Per Page Load (D — 50/100)

*1.35g CO2 per view*

- **[WARNING]** 1.35g CO2 per page view — This page transfers 4.8 MB, producing an estimated 1.35g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.25g, network 0.23g, end-user device 0.86g.
- **[INFO]** At 10,000 monthly views: 161.7 kg CO2/year — With 10,000 page views per month, this page would generate approximately 161.7 kg of CO2 annually — equivalent to charging 20209 smartphones.

### Green Hosting (D — 50/100)

*Unknown*

- **[INFO]** Hosting provider could not be identified — Without knowing the provider, we cannot determine their energy sourcing. Check with your hosting provider about their renewable energy commitments.
- **[INFO]** Green hosting status based on known provider commitments — Green hosting detection uses a curated database of provider renewable energy commitments. This is not a real-time verification. For authoritative checks, visit thegreenwebfoundation.org.

### Repeat Visit Weight (A+ — 100/100)

*100% cached*

- **[PASS]** 100% reduction on repeat visits — Returning visitors download only 10 KB (vs 4871 KB first visit). 81 of 83 resources are served from browser cache, saving 1.34g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.00g CO2 (first visit: 1.35g)

### Carbon Budget (F — 30/100)

*71th percentile*

- **[WARNING]** 1.35g CO2 — above the median website (0.60g) — Heavier than an estimated 29% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 71th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (F — 20/100)

*38% efficient*

- **[CRITICAL]** Transfer efficiency: 38% — An estimated 3008 KB (62%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 3008 KB of unused JavaScript. This wasted data produces 0.83g of unnecessary CO2 per page view.

### Web Font Weight Variants (B — 90/100)

*No detectable Google Fonts weights*

- **[INFO]** No detectable Google Fonts weights — The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
