## Security

### Security Headers (F — 25/100)

*3 of 10 headers properly configured*

- **[CRITICAL]** HSTS header is missing — Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
- **[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.
- **[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 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 (C — 65/100)

*2 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[WARNING]** default-src directive is missing — default-src provides a fallback for other directives. Set it to restrict default resource loading.
- **[INFO]** No script-src or default-src to check for 'unsafe-inline'
- **[INFO]** No script-src or default-src to check for 'unsafe-eval'
- **[INFO]** No script-src or default-src to check for wildcard
- **[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'.
- **[WARNING]** frame-ancestors directive is missing — frame-ancestors controls who can embed your page, preventing clickjacking. Set it to 'self' or 'none'.
- **[WARNING]** form-action directive is missing — form-action restricts where forms can submit data, preventing form hijacking.
- **[PASS]** upgrade-insecure-requests is enabled

### 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 70 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 (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 (A+ — 100/100)

*All 26 new-tab link(s) carry rel=noopener*

- **[PASS]** All 26 new-tab link(s) carry rel=noopener

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

*20 inline style attribute(s) detected*

- **[WARNING]** 20 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. 20 inline style(s) is moderate. Affected element types include: div, p, h2, span, section. 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 (0/1 third-party resources)*

- **[WARNING]** SRI adoption: 0/1 third-party resources protected (0%) — Of 1 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 1 examples):
  - https://fonts.googleapis.com/css2?family=Geist:wght@300;400;500;600;700&family=Inter+Tight:wght@300;400;500;600;700&display=swap

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 2 candidate URL(s))*

- **[PASS]** No source maps accessible across 2 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 1 external resources have SRI*

- **[WARNING]** External link from fonts.googleapis.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 (F — 12/100)

*no DMARC, SPF: ~all*

- **[WARNING]** No DMARC record found — Without DMARC, email receivers have no policy for handling authentication failures. Add a TXT record at _dmarc.<domain> starting with v=DMARC1.
- **[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).
- **[INFO]** No DKIM detected via common selectors — DKIM signs outbound mail to prove origin. We probed common selectors (default, google, selector1, etc.) without finding a record. If you use a non-standard selector, this is a false negative.
- **[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>.
- **[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)

*9.5 MB transferred, 30 requests*

- **[CRITICAL]** Page weighs 9.9 MB (9.5 MB transferred)
- **[WARNING]** Images are 4.6 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[PASS]** 30 HTTP requests
- **[INFO]** Estimated 2.0 g CO2 per page load

### Third-Party Impact (A+ — 100/100)

*1% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 1% of page weight (98.4 KiB of 9.5 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 (C — 65/100)

*20 images, 0 KB saveable*

- **[WARNING]** https://tdsolarenergy.com/assets/img/pv-06.jpeg is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]**  is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (D — 40/100)

*3428ms total JS execution*

- **[WARNING]** https://tdsolarenergy.com/: 1895ms CPU time
- **[WARNING]** Unattributable: 1340ms CPU time
- **[INFO]** https://cdn.jsdelivr.net/npm/motion@11/+esm: 193ms CPU time
- **[INFO]** Third-party scripts: 193ms (6% of total)

### Font Loading (A+ — 100/100)

*2 fonts (73 KB)*

- **[INFO]** 2 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (A+ — 100/100)

*3 scripts, 0 KB unused*


### 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)

*4 hints, 0 missing preconnects*

- **[PASS]** Page uses 4 resource hint(s)

### HTTP/3 (QUIC) (A+ — 100/100)

*HTTP/3 advertised via Alt-Svc*

- **[PASS]** HTTP/3 (QUIC) is supported — First-load mobile users on cellular networks see meaningful latency improvements with HTTP/3. The QUIC transport collapses TLS + TCP handshakes into one and recovers faster from packet loss.

### 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 (B — 80/100)

*No Cache-Control header on main HTML response*

- **[INFO]** Main HTML response has no Cache-Control header — Without an explicit Cache-Control, browsers fall back to heuristic caching (~10% of Last-Modified age). Set `Cache-Control: no-cache` or `max-age=300` for HTML to control freshness explicitly -- prevents stale auth state and SPA shell drift.

### 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+ — 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]** Both `ETag` and `Last-Modified` present -- efficient revalidation supported — The page returns both `ETag` (content hash) and `Last-Modified` (timestamp) headers. Browsers can issue conditional GETs with `If-None-Match` or `If-Modified-Since`; the server returns 304 Not Modified for unchanged content, saving bandwidth. ETag is the more reliable of the two (timestamps fail in DST transitions and clock skew).

### Page Weight Inventory (C — 60/100)

*30 resources · 9.5 MB · 0 KB savings available*

- **[WARNING]** Page weight 9.5 MB exceeds 1 MB target by 8.5 MB
- **[INFO]** 5 third-party resources (1% of weight)
- **[INFO]** 8 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+ — 100/100)

*No CSS performance depth issues detected*

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

---

## Content Quality

### Links (A — 90/100)

*49 links checked, 47 healthy, 2 broken*

- **[WARNING]** 47 of 49 links are healthy
- **[WARNING]** Broken link: https://fonts.googleapis.com — Found in <link href>. Returns HTTP 404.
- **[WARNING]** Broken link: https://fonts.gstatic.com — 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 (A — 95/100)

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

- **[INFO]** og:title is long (75 characters) — Titles over 60 characters may be truncated in social sharing previews.
- **[INFO]** Missing og:site_name — The og:site_name tag displays the website name in social 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 "address" for LocalBusiness — The "address" property is required for the LocalBusiness schema type.
- **[INFO]** Missing recommended property "openingHours" for LocalBusiness — Adding "openingHours" can improve how search engines display your content.

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

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

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

LocalBusiness

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 — 25/100)

*7 issues found across 24 images*

- **[WARNING]** 1 images significantly larger than display size — Resizing to display dimensions could save approximately 460 KB.
- **[WARNING]** 23 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 6 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 17 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]** Total image weight: 1187 KB (1.2 MB) — Consider compressing images, using modern formats, and serving appropriately sized images.
- **[INFO]** 2 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: https://tdsolarenergy.com/assets/img/pv-06.jpeg, https://tdsolarenergy.com/assets/img/pv-05.jpeg.
- **[INFO]** 1 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://tdsolarenergy.com/assets/img/pv-06.jpeg.

### Autoplay Media (B — 90/100)

*1 autoplay media element(s) -- all muted*

- **[INFO]** 1 autoplay media element(s) on page (muted) — Autoplay video transfers bytes whether the user engages or not -- a sustainability concern even when muted. Consider replacing with a static poster image and a click-to-play overlay; the user opts in to the bandwidth cost.

---

## Infrastructure

### DNS Records (A+ — 95/100)

*1 A records, 192 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]** 2 nameserver(s) configured
- **[PASS]** 2 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[PASS]** DNS resolution time: 192 ms

### 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*

- **[INFO]** PTR lookup failed for 92.112.182.90: lookup 92.112.182.90: 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 37ms across 3 resolvers (spread 15ms)*

- **[PASS]** Cloudflare: 29ms
- **[PASS]** Quad9: 39ms
- **[PASS]** Google: 44ms

### Redirect Chain (A+ — 100/100)

*No redirects — direct access*

- **[PASS]** No redirects — direct access

### IPv6 Readiness (C — 60/100)

*No IPv6 support*

- **[INFO]** No IPv6 (AAAA) records found — IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

### Crawlability (B — 75/100)

*no robots.txt, no sitemap*

- **[INFO]** No robots.txt found — robots.txt is optional but recommended. It tells search engine crawlers which pages to index.
- **[INFO]** No sitemap.xml found — A sitemap helps search engines discover and index your pages more efficiently.

### URL Variants (B — 75/100)

*www/non-www, trailing slash, HTTP→HTTPS*

- **[CRITICAL]** Both www and non-www versions serve content
- **[PASS]** HTTP correctly redirects to HTTPS permanently

### Domain Intelligence (A+ — 100/100)

*tdsolarenergy.com — via HOSTINGER operations, UAB, 2 months old, hosted on Hostinger*

- **[PASS]** Domain registered until Jun 24, 2029 (2 years, 9 months remaining)
- **[INFO]** Domain is only 2 months old — Newly registered domains may face SEO trust challenges. Search engines generally give more authority to older domains. This is informational — not a problem to fix.
- **[INFO]** DNSSEC is not enabled — DNSSEC protects against DNS spoofing attacks. While not required, enabling DNSSEC adds an additional layer of security. Contact your DNS provider to enable it.
- **[PASS]** Registrar: HOSTINGER operations, UAB
- **[WARNING]** Registrar lock is NOT enabled — The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.
- **[PASS]** Hosting: Hostinger

### Regulatory Indicators

*0 regulatory indicator(s) detected*

- **[INFO]** This is a technical scan, not a legal assessment — BeaverCheck detects technical indicators that may suggest regulatory relevance. This is not a compliance audit and should not be relied upon for legal decisions. Consult qualified legal counsel for compliance assessments.
- **[INFO]** No specific regulatory indicators detected — No strong signals for GDPR, CCPA, ADA, PCI, HIPAA, or COPPA were found. This does not mean these regulations don't apply — it means we didn't detect common technical indicators.

### Third-Party Data Sharing

*0 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]** No recognized third-party data-sharing services detected — This page does not appear to load external tracking, analytics, or advertising scripts.

### Compliance Badges (C — 55/100)

## Availability

### CDN & Delivery (D — 50/100)

*No CDN (document or assets)*

- **[WARNING]** No CDN (document or assets) — Neither the HTML document nor the page's subresources are served through an edge network. A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (D — 40/100)

*No cache headers*

- **[WARNING]** No Cache-Control header found — Browsers will use heuristic caching, which can be unpredictable. Set explicit cache headers.
- **[PASS]** ETag present — enables conditional (304) responses
- **[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 (A — 85/100)

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

- **[PASS]** HTTP/3 (QUIC) supported — The server advertises HTTP/3 via Alt-Svc for faster connections on mobile networks.
- **[WARNING]** Missing Strict-Transport-Security header — HSTS tells browsers to only use HTTPS, preventing SSL stripping attacks.
- **[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 (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.

## Accessibility

### Landmark Structure (D — 45/100)

*3 landmarks*

- **[CRITICAL]** No <main> landmark found — Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
- **[PASS]** 2 <nav> landmark(s) found
- **[WARNING]** 1 of 2 <nav> elements are unlabeled — Multiple navigations need aria-label to distinguish them for screen readers.
- **[INFO]** No contentinfo (footer) landmark
- **[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 (B — 70/100)

*33 headings, 2 skip(s)*

- **[PASS]** Single H1 present
- **[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: 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)

*All 33 heading(s) have substantive, well-formed text*

- **[PASS]** Heading text quality is clean -- no placeholder, length, or styling issues

### Alt Text Quality (A+ — 100/100)

*All 24 images OK*

- **[PASS]** 9 decorative image(s) correctly marked
- **[PASS]** 15 image(s) with good alt text

- **[PASS]** 30 link(s) with descriptive text

### Form Input Types (A+ — 100/100)

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

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

### Form Input Quality (A+ — 100/100)

*12 form control(s) checked, no input-semantic issues*

- **[PASS]** All form input semantics look correct

### Mobile Keyboard & Autofill (C — 75/100)

*4/8 eligible field(s) missing autocomplete or inputmode*

- **[WARNING]** 4 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: tel, email.

### Document Language (A+ — 100/100)

*Lang attribute set to "de"*

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

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

*0 positive, 2 -1-on-focusable*

- **[INFO]** tabindex="-1" on naturally-focusable <input> — tabindex="-1" removes an element from the keyboard tab order. Naturally-focusable elements (links, buttons, form controls) become unreachable for keyboard users. (Common false-positive: hidden honeypot fields. Verify the element is genuinely interactive before removing the tabindex.)
- **[INFO]** tabindex="-1" on naturally-focusable <input> — tabindex="-1" removes an element from the keyboard tab order. Naturally-focusable elements (links, buttons, form controls) become unreachable for keyboard users. (Common false-positive: hidden honeypot fields. Verify the element is genuinely interactive before removing the tabindex.)

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

*All 1 iframe(s) have descriptive titles*

- **[PASS]** All 1 iframe(s) have title attributes

### Tap Target Adequacy (A+ — 100/100)

*All tap targets meet WCAG 2.5.5/2.5.8 sizing*

- **[PASS]** All tap targets meet WCAG 2.5.5 (44x44px) sizing

### Mobile-Readable Font Sizes (B — 90/100)

*97% of visible text renders at >= 12 CSS px (4 below threshold)*

- **[INFO]** 4 text node(s) render below 12 CSS pixels on mobile — Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <small> 11.0px ("DC Montage"); <a> 11.0px ("Impressum"); <a> 11.0px ("Datenschutzerklärung"); <a> 11.0px ("Cookie-Richtlinie").

- **[WARNING]** No favicon.ico at site root — Some older browsers, bookmark tools, and RSS readers look for /favicon.ico. Add one as a fallback.
- **[PASS]** HTML icon links detected
- **[INFO]** No apple-touch-icon detected — iOS devices use this when users add your site to their home screen. Add <link rel='apple-touch-icon' sizes='180x180' href='/apple-touch-icon.png'>.

### Web Manifest (D — 40/100)

*Not found*

- **[INFO]** No web manifest found — No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

### PWA Depth (A+ — 100/100)

*No PWA depth issues detected*

- **[PASS]** No PWA depth issues detected

### Dark Mode Support (D — 45/100)

*Theme color only*

- **[INFO]** Theme-color present but no dark variant — A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.
- **[INFO]** No dark mode signals detected — Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.
- **[INFO]** Detection limited to meta tags and inline styles — External CSS files may contain prefers-color-scheme rules not visible to this scan.

### 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.

### Navigation UX (F — 15/100)

*No navigation patterns*

- **[PASS]** 2 navigation landmark(s) detected
- **[INFO]** No breadcrumbs, search, or skip link detected — These navigation aids help users orient themselves and find content efficiently, especially on large sites.

### Mobile UX Depth (A+ — 100/100)

*1 mobile-depth signal(s) detected*

- **[PASS]** Browser-chrome `theme-color` meta tag present — The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.

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

### Sitemap Freshness (C — 75/100)

*No sitemap.xml found*

- **[INFO]** No sitemap.xml found — Sitemaps help search engines discover and prioritize URLs. Not strictly required for small sites where every page is linked from the homepage, but recommended once a site grows beyond a few dozen URLs.

### Sitemap × Robots Consistency (C — 75/100)

*Sitemap or robots.txt missing -- consistency check skipped*

- **[INFO]** Cross-check skipped (sitemap or robots.txt absent)

### Sitemap Hygiene (A+ — 100/100)

*1 markup-quality issue(s) detected*

- **[INFO]** 1 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 (F — 30/100)

*2.24g CO2 per view*

- **[CRITICAL]** 2.24g CO2 per page view — This page transfers 9.5 MB, producing an estimated 2.24g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.06g, network 0.46g, end-user device 1.72g.
- **[INFO]** At 10,000 monthly views: 269.2 kg CO2/year — With 10,000 page views per month, this page would generate approximately 269.2 kg of CO2 annually — equivalent to charging 33649 smartphones.
- **[PASS]** Green hosting reduces data center emissions

### Green Hosting (B — 80/100)

*Green (hosting)*

- **[PASS]** Hostinger uses renewable energy
- **[INFO]** Hostinger: Verified by the Green Web Foundation
- **[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 11 KB (vs 9705 KB first visit). 29 of 30 resources are served from browser cache, saving 2.24g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.00g CO2 (first visit: 2.24g)

### Carbon Budget (F — 15/100)

*95th percentile*

- **[WARNING]** 2.24g CO2 — above the median website (0.60g) — Heavier than an estimated 5% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 95th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (A+ — 100/100)

*100% efficient*

- **[PASS]** Transfer efficiency: 100% — Only 0 KB of potential savings identified. Your page is well-optimized for size.

### Web Font Weight Variants (C — 70/100)

*10 font weights loaded across 2 famil(y/ies)*

- **[WARNING]** 10 font weights loaded -- likely 100+ KB of unused payload — Loading 10 font weights typically transfers 200-400 KB just for fonts. Most pages legitimately use 2-3 weights (regular + bold, maybe medium). Audit which weights your stylesheet actually applies and trim the Google Fonts URL accordingly. Affected families: Geist, Inter Tight.
