## Security

### Security Headers (F — 30/100)

*3 of 10 headers properly configured*

- **[WARNING]** HSTS is enabled but max-age is short (15552000s, should be >= 31536000s) — The header is present and enforced, so first-visit protection is already in place; a short max-age just means the browser forgets it sooner. Set max-age to at least 31536000 (1 year).
- **[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.
- **[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 present without version info
- **[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, 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 78 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 (A — 90/100)

*Cloudflare*

- **[PASS]** Cloudflare detected — Detected via: cf-ray: a57df2ee28dc6107-CDG

### security.txt (C — 60/100)

*No security.txt file found*

- **[INFO]** No security.txt file found — security.txt (RFC 9116) provides a standardized way for security researchers to report vulnerabilities. Create one at /.well-known/security.txt with at least a Contact field.

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

*31 of 33 new-tab link(s) missing rel=noopener*

- **[WARNING]** 31 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)

*28 inline style attribute(s) detected*

- **[WARNING]** 28 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. 28 inline style(s) is moderate. Affected element types include: a, div, img, span. 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)

*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 (D — 50/100)

*6% SRI adoption (1/15 third-party resources)*

- **[WARNING]** SRI adoption: 1/15 third-party resources protected (6%) — Of 15 third-party `<script>` / `<link rel=stylesheet>` resources, 1 (6%) 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):

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 (A+ — 100/100)

*No source maps accessible (probed 10 candidate URL(s))*

- **[PASS]** No source maps accessible across 10 probed candidate(s)

### HTML Version Disclosure (C — 75/100)

*1 software version(s) disclosed in HTML*

- **[WARNING]** 1 software version(s) disclosed in HTML: WPML ver:4.5.5 stt:1,3; — Each disclosed version enables direct CVE lookup -- an attacker who knows you run WordPress 6.4.2 (or whatever specific version) can search the CVE database for known exploits and target accordingly. Remove via your CMS config: WordPress (`remove_action('wp_head', 'wp_generator')`); Drupal (System / Reports / Status report -> Hide generator); Joomla (Global Configuration -> Hide generator); Hugo/Jekyll (delete or override the {{ .Site.Generator }} template hook). For HTML comments, audit your template files directly.

### 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 (B — 80/100)

*3 auth-security finding(s) on the login page*

- **[PASS]** Login page detected — The page contains a `type=password` input and at least one identifier field (username / email). Auth-security findings below evaluate the page's hardening posture.
- **[WARNING]** Login form does not contain a recognizable CSRF token — Standard frameworks emit CSRF tokens as a hidden input named `_csrf`, `csrf_token`, `csrfmiddlewaretoken` (Django), `authenticity_token` (Rails), or `__RequestVerificationToken` (ASP.NET). None of those were found. Possibilities: (1) the form posts to an API that uses a custom header or SameSite cookie reliance for CSRF -- legitimate but not visible from this scan, (2) the form is genuinely missing CSRF protection, which would let an attacker submit logins from another origin via a hidden POST. Verify the auth flow has SOME CSRF defense.
- **[INFO]** No password-reset link found on the login page — Login pages should link to a password-reset flow (typically /forgot, /reset, or a 'Forgot password?' link). Absence usually means the reset flow lives elsewhere on the site (separately reachable), but if it's truly missing, users locked out of accounts have no self-service recovery path.

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

*No risky subdomain names in certificate SANs*

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

- **[PASS]** script from static.cloudflareinsights.com has SRI protection
- **[WARNING]** External script from zn3rbqbel717pvo3i-schalke04.siteintercept.qualtrics.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*

- **[INFO]** No security.txt found — Consider adding a security.txt at /.well-known/security.txt.
- **[PASS]** No sensitive files exposed

### Email Security (B — 77/100)

*DMARC: quarantine, SPF: ~all, DKIM, BIMI*

- **[PASS]** DMARC policy is quarantine — good protection
- **[INFO]** DMARC configured without rua= aggregate reporting — Without rua=, you have no visibility into spoof attempts or auth failures from your own legitimate senders. Add rua=mailto:dmarc@<your-domain> (or a managed inbox at a reporting service).
- **[INFO]** SPF ends in ~all (soft fail) — Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify).
- **[PASS]** DKIM configured (selectors: selector1)
- **[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.
- **[INFO]** TLS-RPT not configured — TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.<domain>.
- **[PASS]** BIMI configured and DMARC enforced — logo will display

### 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 — 15/100)

*3.4 MB transferred, 202 requests*

- **[WARNING]** Page weighs 11.3 MB (3.4 MB transferred)
- **[WARNING]** JavaScript is 1.3 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[WARNING]** Images are 1.2 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[INFO]** Fonts are 638 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[INFO]** CSS is 201 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size.
- **[WARNING]** 202 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 0.71 g CO2 per page load

### Third-Party Impact (B — 70/100)

*48% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 48% of page weight (1.6 MiB of 3.4 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

### 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)

*10 hints, 0 missing preconnects*

- **[PASS]** Page uses 10 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 (A+ — 100/100)

*Document response uses brotli*

- **[PASS]** Main HTML response uses brotli (Content-Encoding: br) — Brotli is the best text-compression algorithm for general use, ~20% smaller than gzip on average (40% on smaller files). Modern browsers all support it.

### Asset Compression

*No text asset hosts to measure*

- **[INFO]** No third-party or subdomain host served enough text assets to measure — Asset compression is measured per host, from one HEAD request against a sampled resource. Pages that serve all their JS and CSS from the document's own origin are covered by the document compression check instead.

### 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-store -- correct for sensitive/dynamic content*

- **[PASS]** Main HTML uses no-store -- correct for sensitive/dynamic content

### Server-Timing Observability (A+ — 100/100)

*3 Server-Timing entries advertised*

- **[PASS]** Server-Timing header advertises 3 timing entries

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

*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).
- **[PASS]** `Last-Modified` present -- timestamp-based conditional GET supported — Consider also setting `ETag` for stronger revalidation -- ETags are content hashes that don't suffer from clock-skew or DST issues. Last-Modified alone is functional for conditional GETs and not a bug.

### Page Weight Inventory (F — 35/100)

*202 resources · 3.4 MB · 547 KB savings available*

- **[WARNING]** Page weight 3.4 MB exceeds 1 MB target by 2.4 MB
- **[INFO]** ~547 KB of savings available
- **[WARNING]** 114 third-party resources (48% of weight)
- **[INFO]** 2 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]** 9 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 6.3 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 — 88/100)

*1 CSS depth issue(s) detected*

- **[WARNING]** 8 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+ — 98/100)

*200 links checked, 199 healthy, 0 broken*

- **[PASS]** 199 of 200 links are healthy
- **[INFO]** Long redirect chain: https://veltins-arena.de/kindergeburtstag/ (3 hops)

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (A — 90/100)

*Open Graph tags are well configured for social sharing.*

- **[CRITICAL]** og:image is not reachable — The og:image URL could not be fetched. Social platforms won't be able to display it.
- **[INFO]** og:title is short (8 characters) — Ideal length is 25–60 characters for social sharing previews.

### 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 — 90/100)

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

- **[WARNING]** Missing required property "name" for Organization — The "name" property is required for the Organization schema type.
- **[INFO]** Missing recommended property "url" for Organization — Adding "url" can improve how search engines display your content.
- **[INFO]** Missing recommended property "logo" for Organization — Adding "logo" can improve how search engines display your content.
- **[INFO]** Missing recommended property "sameAs" for Organization — Adding "sameAs" can improve how search engines display your content.

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

*1 JSON-LD block(s) declaring 5 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]** 5 rich-result schema type(s) declared — Inventory of structured-data types on the page (each may unlock a different SERP feature):

BreadcrumbList, ImageObject, Organization, 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 (F — 45/100)

*5 issues found across 66 images*

- **[WARNING]** 5 images significantly larger than display size — Resizing to display dimensions could save approximately 36 KB.
- **[WARNING]** 64 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 57 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 37 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]** 10 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://storage.schalke04.de/sites/1/2026/05/260511_keyvisual_sgu_homepagebg-992x558.jpg, https://storage.schalke04.de/sites/1/2026/11/261109_adamu-992x558.jpg, https://storage.schalke04.de/sites/1/2026/11/261109_mulder-992x558.jpg (+7 more).

### 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)

*0/4 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 172.66.153.234: lookup 172.66.153.234: 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 104.20.40.87: lookup 104.20.40.87: 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.

### Third-Party Data Sharing

*4 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]** 4 third-party services across 3 categories — 4 third-party services detected across 3 categories: Analytics (1), Tag Management (1), Advertising (2). Each of these services receives some user data from your site visitors.

## Availability

### CDN & Delivery (B — 80/100)

*Document and assets on Cloudflare*

- **[PASS]** Document is served via Cloudflare CDN (edge: CDG)
- **[INFO]** CDN cache status: BYPASS
- **[PASS]** Assets on Cloudflare: storage.schalke04.de (assets: 31), cache HIT

### HTTP Caching (D — 45/100)

*no-store (uncacheable)*

- **[INFO]** Cache-Control: no-store prevents all caching — Intentional for dynamic content, but increases server load for every page view.
- **[PASS]** Last-Modified header present

### 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 (B — 75/100)

*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.
- **[WARNING]** HSTS max-age is short: 180 days — HSTS max-age should be at least 1 year (31536000 seconds).
- **[PASS]** HSTS preload enabled
- **[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: BYPASS*

- **[PASS]** CDN cache state observable via 1 header(s)

## Accessibility

### Landmark Structure (D — 50/100)

*8 landmarks*

- **[CRITICAL]** No <main> landmark found — Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
- **[PASS]** 4 <nav> landmark(s) found
- **[WARNING]** 4 of 4 <nav> elements are unlabeled — Multiple navigations need aria-label to distinguish them for screen readers.
- **[WARNING]** Skip navigation link is missing (WCAG 2.4.1) — Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

### Heading Hierarchy (A — 90/100)

*51 headings*

- **[WARNING]** Multiple H1 headings (2 found) — A page should have only one H1. Multiple H1s dilute the document outline.

### Heading Text Quality (A+ — 95/100)

*1 heading-text-quality issue(s) detected*

- **[INFO]** 17 heading(s) are all-uppercase (excluding short acronyms) — Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.

### Alt Text Quality (A+ — 96/100)

*All 66 images OK*

- **[INFO]** 2 image(s) with alt text over 125 characters
- **[PASS]** 3 decorative image(s) correctly marked
- **[PASS]** 61 image(s) with good alt text

### Form Accessibility (A+ — 100/100)

*All 6 controls labeled*

- **[PASS]** 6 control(s) properly labeled

### Link & Button Quality (A — 88/100)

*316 links, 61 buttons — all OK*

- **[WARNING]** 38 link(s) open in new tab without warning — Add '(opens in new tab)' to link text or aria-label.
- **[PASS]** 278 link(s) with descriptive text

### Form Input Types (A+ — 100/100)

*6 form control(s) checked, no type mismatches*

- **[PASS]** No input-type mismatches detected

### Form Input Quality (B — 82/100)

*2 input-semantic issue(s) across 6 form control(s)*

- **[INFO]** 1 password field(s) missing or with invalid `autocomplete` — Password managers fill / save passwords only when `autocomplete` is exactly `current-password` (login) or `new-password` (registration / change). Empty, `off`, `password`, or other values silently disable the manager UX. Sample: <input type="password" name="password">.
- **[INFO]** 2 login form field(s) missing `autocomplete=username` (or `email`) — On a page with a password input, the matching username / email field needs `autocomplete="username"` or `autocomplete="email"` -- otherwise the password manager can't identify which field carries the login identifier and silently skips autofill on the whole form. Sample: <input type="email" name="email">, <input type="email" name="email">.

### Mobile Keyboard & Autofill (D — 60/100)

*6/6 eligible field(s) missing autocomplete or inputmode*

- **[WARNING]** 3 field(s) missing recommended autocomplete attribute — WCAG 1.3.5 (Level AA): inputs whose purpose maps to a Common Input Purpose value should declare it via `autocomplete=`. Required for password managers, browser autofill, and assistive tech that customizes inputs (e.g., simplified keyboards). Mobile autofill in particular cuts form-completion time by 30-50% when these are present. Affected purposes: email, current-password.
- **[WARNING]** 3 field(s) would benefit from inputmode attribute — Mobile browsers pick the on-screen keyboard layout from `inputmode=` when present (numeric pad, tel dialpad, email keyboard). Without it, users see the default text keyboard and must mode-switch -- 2-3 extra taps per phone-number or numeric-ID field. Type-based defaults exist (`type=tel` shows the tel keyboard on most browsers) but `inputmode` is the explicit, cross-browser way to control this. Affected types: search, email.

### Document Language (A+ — 100/100)

*Lang attribute set to "de-DE"*

- **[PASS]** <html lang="de-DE"> is set and valid

### Tabindex Anti-Patterns (D — 40/100)

*0 positive, 16 -1-on-focusable*

### Markup Quality (A — 87/100)

*2 markup-quality issue(s) detected*

- **[INFO]** `<meta charset>` declared at byte 1039 -- past the 1024-byte spec window — The HTML5 spec requires the encoding declaration to appear in the first 1024 bytes. Browsers that started parsing in a default encoding and discover the real charset later DISCARD parsing state and re-parse from the top -- a measurable hit to First Contentful Paint. Move the `<meta charset>` tag to be the first child of `<head>`.
- **[INFO]** 7 redundant ARIA role attribute(s) on native semantic element(s) — The W3C "ARIA in HTML" spec calls this its first rule: don't use ARIA when a native HTML element already conveys the semantics. `<button role="button">`, `<a href role="link">`, `<nav role="navigation">`, `<main role="main">` -- the role attribute either does nothing or shadows the native semantic, occasionally breaking assistive-tech behaviors. Remove the redundant role.

## Sustainability

### CO2 Per Page Load (D — 50/100)

*0.80g CO2 per view*

- **[INFO]** 0.80g CO2 per page view — This page transfers 3.4 MB, producing an estimated 0.80g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.02g, network 0.17g, end-user device 0.62g.
- **[INFO]** At 10,000 monthly views: 96.5 kg CO2/year — With 10,000 page views per month, this page would generate approximately 96.5 kg of CO2 annually — equivalent to charging 12064 smartphones.
- **[PASS]** Green hosting reduces data center emissions

- **[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)

*99% cached*

- **[PASS]** 99% reduction on repeat visits — Returning visitors download only 30 KB (vs 3479 KB first visit). 193 of 202 resources are served from browser cache, saving 0.80g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.01g CO2 (first visit: 0.80g)

### Carbon Budget (D — 50/100)

*55th percentile*

- **[WARNING]** 0.80g CO2 — above the median website (0.60g) — Heavier than an estimated 45% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 55th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (B — 80/100)

*84% efficient*

- **[INFO]** Transfer efficiency: 84% — An estimated 546 KB (16%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 546 KB of unused JavaScript. This wasted data produces 0.13g 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.
