## Security

### Security Headers (B — 70/100)

*6 of 10 headers properly configured*

- **[WARNING]** HSTS is enabled but missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP.
- **[PASS]** X-Content-Type-Options is properly configured
- **[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.
- **[PASS]** Referrer-Policy is properly configured
- **[PASS]** Permissions-Policy is set
- **[PASS]** Content-Security-Policy is present
- **[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 (D — 50/100)

*5 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[PASS]** default-src directive is set
- **[CRITICAL]** 'unsafe-inline' found in script source — 'unsafe-inline' allows inline <script> tags, defeating CSP against XSS. Remove it and use nonces or hashes instead.
- **[CRITICAL]** 'unsafe-eval' found in script source — 'unsafe-eval' allows eval() and similar functions, enabling code injection. Remove it.
- **[PASS]** No wildcard in script source
- **[PASS]** object-src falls back to default-src
- **[WARNING]** base-uri directive is missing — Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
- **[PASS]** frame-ancestors directive is set
- **[PASS]** form-action directive is set
- **[INFO]** upgrade-insecure-requests is not set — This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.

### TLS & Certificates (A+ — 100/100)

*TLS 1.3, 8 checks passed*

- **[PASS]** TLS 1.3 is used
- **[PASS]** Strong cipher suite is used
- **[PASS]** HTTP/2 is negotiated
- **[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 4 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 2 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 (A+ — 100/100)

*Vulnerability disclosure policy*

- **[PASS]** security.txt found

### Cross-Origin Tab Safety (D — 60/100)

*22 of 22 new-tab link(s) missing rel=noopener*

- **[WARNING]** 22 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 (B — 90/100)

*9 inline style attribute(s) detected*

- **[INFO]** 9 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. 9 inline style(s) is low. Affected element types include: img, h2, a, div. 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) (B — 95/100)

*Trusted Types not enabled*

- **[INFO]** Trusted Types not enabled — Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode.

### 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)

*No soft-404 patterns detected in page title or headings*

- **[PASS]** No soft-404 patterns detected in page title or headings

### 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 (F — 30/100)

*0% SRI adoption (0/7 third-party resources)*

- **[WARNING]** SRI adoption: 0/7 third-party resources protected (0%) — Of 7 third-party `<script>` / `<link rel=stylesheet>` resources, 0 (0%) 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://www.googletagmanager.com/gtag/js?id=G-0QFX5FC072&cx=c&gtm=4e6ba1
  - https://www.googletagmanager.com/gtm.js?id=GTM-W3STJSW2
  - https://fonts.bunny.net/css2?family=Open+Sans:wght@300;400;500;600;700;800&family=Poppins:wght@400;700&display=swap
  - https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js?lfr=My43LjE%3D
  - https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.4/js/bootstrap.min.js?lfr=Ny4xLjQ%3D

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 (A — 85/100)

*90% high-risk feature coverage (9/10)*

- **[PASS]** Permissions-Policy covers 9/10 high-risk features (90%) — The Permissions-Policy header explicitly declares policies for 9/10 high-risk features.

Covered: camera, microphone, geolocation, payment, usb, midi, accelerometer, gyroscope, magnetometer

Not declared (default-allow): serial

The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them.

### Referrer-Policy Strictness (A+ — 100/100)

*Referrer-Policy is `strict-origin-when-cross-origin` (modern default -- full URL same-origin, origin-only cross-origin)*

- **[PASS]** Referrer-Policy: `strict-origin-when-cross-origin` -- modern default -- full URL same-origin, origin-only cross-origin — The modern browser default (Chrome 85+, Firefox 87+, Safari 15+). Full URL Referer on same-origin; origin only on cross-origin; no Referer on HTTPS-to-HTTP downgrade. Privacy-safe and breaks no analytics. The recommended explicit value.

### Source Map Exposure (A+ — 100/100)

*No source maps accessible (probed 9 candidate URL(s))*

- **[PASS]** No source maps accessible across 9 probed candidate(s)

### 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

## Advanced Security

### Subresource Integrity (F — 20/100)

*0 of 7 external resources have SRI*

- **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from fonts.bunny.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from cdnjs.cloudflare.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from cdnjs.cloudflare.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from cdn-eu.readspeaker.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from cdn-eu.readspeaker.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.

### 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, TLS-RPT*

- **[PASS]** DMARC policy is reject — strongest protection
- **[PASS]** SPF ends in -all (hard fail) — strongest setting
- **[PASS]** DKIM configured (selectors: selector1, key1, fm1, fm2)
- **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.
- **[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 (A+ — 100/100)

## Performance

### Page Weight Budget (B — 76/100)

*1.3 MB transferred, 394 requests*

- **[PASS]** Page weighs 2.7 MB (1.3 MB transferred)
- **[INFO]** Fonts are 616 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[WARNING]** 394 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 0.28 g CO2 per page load

### Third-Party Impact (A — 85/100)

*34% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 34% of page weight (460.3 KiB of 1.3 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (A — 90/100)

*5 images, 0 KB saveable*

- **[PASS]** All images are well-optimized

### JS Execution Cost (D — 40/100)

*2612ms total JS execution*

- **[WARNING]** Unattributable: 868ms CPU time
- **[WARNING]** https://krimpenaandenijssel.nl/: 811ms CPU time
- **[WARNING]** https://krimpenaandenijssel.nl/app/themes/lyfter-c...: 297ms CPU time
- **[INFO]** https://www.googletagmanager.com/gtag/js?id=G-0QFX...: 213ms CPU time
- **[INFO]** https://www.googletagmanager.com/gtm.js?id=GTM-W3S...: 162ms CPU time
- **[INFO]** Third-party scripts: 492ms (19% of total)

### Font Loading (A+ — 100/100)

*138 fonts (616 KB)*

- **[INFO]** 138 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (B — 80/100)

*20 scripts, 140 KB unused*

- **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-0QFX...: 76 KB unused (43%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.googletagmanager.com/gtm.js?id=GTM-W3S...: 65 KB unused (54%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 140 KB

### 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)

*2 hints, 0 missing preconnects*

- **[PASS]** Page uses 2 resource hint(s)

### 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.

### Document Compression (B — 80/100)

*Document response uses gzip; brotli would be ~20% smaller*

- **[INFO]** Main HTML response uses gzip (brotli would be ~20% smaller) — All current browsers support brotli. Most CDNs (Cloudflare, Fastly, AWS CloudFront, Vercel, Netlify) can switch from gzip to brotli with a single config flag. Origin servers (nginx, Apache) need a brotli module compiled in -- nginx-brotli or Apache mod_brotli.

### Asset Compression (A — 90/100)

*1 of 1 asset host still on gzip*

- **[INFO]** cdn-eu.readspeaker.com serves assets with gzip; brotli would be ~20% smaller (assets: 3) — Every current browser accepts brotli. On a CDN this is a per-pull-zone toggle (Cloudflare, Fastly, CloudFront, CDN77, Bunny all expose it); on an origin it needs the brotli module (nginx-brotli, Apache mod_brotli). The saving lands on the assets this host serves, not on the HTML document -- the document's own encoding is reported separately.

### 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 (B — 90/100)

*Main HTML max-age=3600 (~60min)*

- **[INFO]** Main HTML cached for 60 minutes -- mild staleness risk

### 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)

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: Accept-Encoding — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[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 (C — 65/100)

*394 resources · 1.3 MB · 140 KB savings available*

- **[WARNING]** Page weight 1.3 MB exceeds 1 MB target by 343 KB
- **[INFO]** ~140 KB of savings available
- **[INFO]** 362 third-party resources (34% of weight)
- **[INFO]** 1 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 (A — 94/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** 1 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.

### CSS Performance Depth (A — 88/100)

*1 CSS depth issue(s) detected*

- **[WARNING]** 7 render-blocking stylesheet(s) -- recommended: <=3 — Each `<link rel="stylesheet">` without a non-blocking `media` attribute holds up the first paint. Browsers download all of them before painting any content. Consolidate into 1-2 critical-path stylesheets; defer non-critical CSS via `<link rel="stylesheet" media="print" onload="this.media='all'">` or via the loadCSS pattern; inline above-the-fold CSS in `<style>` to short-circuit the request entirely.

---

## Content Quality

### Links (A — 95/100)

*118 links checked, 117 healthy, 1 broken*

- **[WARNING]** 117 of 118 links are healthy
- **[WARNING]** Broken link: https://krimpenaandenijssel.nl/wp/xmlrpc.php?rsd — Found in <link href>. Returns HTTP 404.

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (C — 70/100)

*Open Graph tags are partially configured — some improvements recommended.*

- **[WARNING]** Missing og:description — The og:description tag controls the description in social sharing previews.
- **[WARNING]** Missing og:image — The og:image tag provides a preview image for social sharing.

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

*OG image dimensions and Twitter card configuration look healthy*

- **[PASS]** OG/Twitter Card depth is clean -- dimensions, card type, and inheritance all valid

### Structured Data (A+ — 100/100)

*1 JSON-LD block(s) found — structured data is well configured.*

- **[PASS]** Custom type "WebPage" — unable to validate specific properties

### Rich Results Eligibility (A+ — 100/100)

*1 JSON-LD block(s) declaring 3 schema type(s)*

- **[PASS]** SiteLinks Search Box markup detected — The page declares a `WebSite` schema with a `potentialAction` of `SearchAction`. This makes the homepage eligible for Google's in-SERP search box -- a high-visibility SERP feature for branded queries.
- **[PASS]** 3 rich-result schema type(s) declared — Inventory of structured-data types on the page (each may unlock a different SERP feature):

BreadcrumbList, WebPage, WebSite

Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.

### Image Optimization (C — 70/100)

*4 issues found across 8 images*

- **[INFO]** 6 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 2 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.
- **[INFO]** 3 image(s) wider than 400px without srcset (no responsive serving) — These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: data:, data:, data:.
- **[INFO]** 2 image(s) rendered at a different aspect ratio than the source — The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://krimpenaandenijssel.nl/app/themes/lyfter-child/dist/assets/brand-logo-64e6a772.png, https://krimpenaandenijssel.nl/app/uploads/2026/06/i-HhnfXm3-X3-768x512.jpg.

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

---

- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[PASS]** Has 1 IPv6 (AAAA) record(s)
- **[PASS]** 3 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT

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

### DNSSEC (A+ — 100/100)

*Signed and validating*

- **[PASS]** DNSSEC fully signed and chain validates (RSASHA256)

### CAA Records (A — 90/100)

*issue: awstrust.com, certsign.ro, digicert.com, letsencrypt.org | issuewild: digicert.com*

- **[PASS]** CAA issue tag present — authorized CA(s): awstrust.com, certsign.ro, digicert.com, letsencrypt.org
- **[INFO]** No CAA iodef tag — won't be notified of failed issuance attempts — Add `0 iodef "mailto:security@example.com"` to receive notifications when a CA refuses issuance because it doesn't match your CAA policy. Useful signal for detecting issuance attempts by unauthorized CAs.

### Reverse DNS (C — 60/100)

*0/2 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 178.22.63.101: lookup 178.22.63.101: no such host — No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.
- **[INFO]** PTR lookup failed for 2a00:1e28:3:a027::1: lookup 2a00:1e28:3:a027::1: no such host — No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.

### Multi-Resolver DNS Speed (A+ — 100/100)

*Mean 40ms across 3 resolvers (spread 33ms)*

- **[INFO]** GDPR indicators detected (strong confidence) — Indicators suggesting GDPR may be relevant: European TLD detected: .nl; Privacy policy page found. EU General Data Protection Regulation — governs collection and processing of personal data of EU residents.

### Third-Party Data Sharing

*3 third-party service(s) detected*

- **[INFO]** Data inventory for transparency purposes — This inventory identifies third-party services that receive data from your site visitors. Under regulations like GDPR (Article 30), maintaining records of data processing activities is commonly considered a best practice. This automated scan provides a starting point — it may not capture all data flows.
- **[INFO]** 3 third-party services across 3 categories — 3 third-party services detected across 3 categories: Analytics (1), Tag Management (1), CDN (1). Each of these services receives some user data from your site visitors.

## Availability

### CDN & Delivery (C — 65/100)

*Assets on CDN77 (host cdn-eu.readspeaker.com, 3 assets); document served directly from origin*

- **[WARNING]** Document not behind existing CDN (CDN77 serves the assets) — The page's subresources are delivered by CDN77 (cdn-eu.readspeaker.com, 3 assets), but the HTML document itself comes straight from the origin. Routing the document through the CDN already in use is the cheapest latency win available here -- the provider relationship, the certificate and the config already exist. A short edge TTL with stale-while-revalidate suits HTML that changes often; if the response is genuinely per-user, edge TLS termination alone still removes a full round trip from every visitor's first byte.
- **[PASS]** Assets on CDN77: cdn-eu.readspeaker.com (assets: 3)

### HTTP Caching (A+ — 95/100)

*max-age=3600 (1 hour)*

- **[PASS]** Cache-Control header is set
- **[PASS]** Effective TTL: 1 hour (max-age=3600)
- **[PASS]** CDN TTL: 1 day (s-maxage=86400)

### 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]** HSTS enabled (base policy)
- **[INFO]** HSTS missing includeSubDomains — Without includeSubDomains, HSTS only protects the exact domain.
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### Health Check Endpoint (B — 80/100)

*No conventional health endpoint found*

- **[INFO]** No conventional health endpoint found — Health endpoints (/health, /healthz, /status, /ping, /api/health) let uptime monitors, load balancers, and orchestration systems (Kubernetes, ECS, Fly.io) verify the service is alive. Marketing sites and small services often skip them legitimately; flagged as Info, not a failure. Probe results: /api/health: 404, /health: 404, /healthz: 404, /ping: 404, /status: 404.

### CDN Cache Observability (A+ — 100/100)

*Cache state: HIT*

- **[PASS]** CDN cache state observable via 3 header(s)

### Heading Hierarchy (D — 45/100)

*13 headings, 3 skip(s)*

- **[WARNING]** Multiple H1 headings (2 found) — A page should have only one H1. Multiple H1s dilute the document outline.
- **[WARNING]** Heading level skipped: H2 → H5 (missing H3) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
- **[WARNING]** Heading level skipped: H1 → H3 (missing H2) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
- **[WARNING]** Heading level skipped: H2 → H4 (missing H3) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

### Heading Text Quality (A+ — 100/100)

- **[PASS]** <html lang="nl-NL"> is set and valid

### Tabindex Anti-Patterns (A — 90/100)

*1 positive, 0 -1-on-focusable*

- **[WARNING]** Positive tabindex on <a>: tabindex=1 — Positive tabindex values force an element into a specific position in the tab order, breaking the natural document flow. Almost always a bug. Use tabindex="0" to make non-focusable elements focusable, or remove the attribute entirely to keep natural order.

### Iframe Accessibility (A+ — 100/100)

*No iframes on this page*

Failing targets cause mis-taps for users with motor impairments, large fingers, or shaky hands -- and are a major bounce-rate driver on mobile commerce flows. Lighthouse measures rendered rects + adjacent-element spacing; the failing list is in the Lighthouse 'tap-targets' audit detail panel.

### Mobile-Readable Font Sizes (A+ — 100/100)

*All 82 visible text node(s) render at >= 12 CSS pixels*

### Print Stylesheet (D — 40/100)

*No print styles*

- **[INFO]** No print-specific styles detected — When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

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

*98% cached*

- **[PASS]** 98% reduction on repeat visits — Returning visitors download only 24 KB (vs 1366 KB first visit). 393 of 394 resources are served from browser cache, saving 0.31g CO2 per repeat visit.

*90% efficient*

- **[INFO]** Transfer efficiency: 90% — An estimated 140 KB (10%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 140 KB of unused JavaScript. This wasted data produces 0.03g 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.
