## Security

### Security Headers (F — 5/100)

*1 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.
- **[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.
- **[WARNING]** X-Powered-By header reveals technology stack — This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it.
- **[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 89 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 1 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*1 cookies analyzed, 3 checks passed*

- **[PASS]** Cookie '__cf_bm' has the Secure flag
- **[PASS]** Cookie '__cf_bm' has the HttpOnly flag
- **[PASS]** Cookie '__cf_bm' has SameSite=None

### Cookie Hygiene (A+ — 100/100)

*All 1 cookie(s) pass hygiene checks*

- **[PASS]** All 1 cookie(s) pass hygiene checks

### WAF / Bot Protection (A — 90/100)

*Cloudflare*

- **[PASS]** Cloudflare detected — Detected via: cf-ray: a44ea08c3ceae8a1-MAD

### 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)

*10 of 10 new-tab link(s) missing rel=noopener*

- **[WARNING]** 10 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 (A+ — 100/100)

*No inline style attributes -- strict CSP is feasible*

- **[PASS]** No inline style attributes detected

### 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 (F — 30/100)

*0% SRI adoption (0/5 third-party resources)*

- **[WARNING]** SRI adoption: 0/5 third-party resources protected (0%) — Of 5 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://snap.licdn.com/li.lms-analytics/insight.old.min.js
  - https://snap.licdn.com/li.lms-analytics/insight.min.js
  - https://www.googletagmanager.com/gtag/js?id=G-BSRJMQ4XBQ
  - https://unpkg.com/gsap@3.12.2/dist/gsap.min.js
  - https://unpkg.com/gsap@3.12.2/dist/ScrollTrigger.min.js

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 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 5 external resources have SRI*

- **[WARNING]** External script from snap.licdn.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from snap.licdn.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 script from unpkg.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from unpkg.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 — 72/100)

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

- **[PASS]** DMARC policy is quarantine — good protection
- **[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, intercom, s1, s2)
- **[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)

*7.9 MB transferred, 70 requests*

- **[CRITICAL]** Page weighs 9.1 MB (7.9 MB transferred)
- **[WARNING]** Images are 1.8 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[INFO]** 70 HTTP requests
- **[INFO]** Estimated 1.7 g CO2 per page load

### Third-Party Impact (A+ — 100/100)

*5% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 5% of page weight (435.8 KiB of 7.9 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 — 60/100)

*17 images, 0 KB saveable*

- **[WARNING]** https://advancedenergyunited.org/wp-content/upload... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://advancedenergyunited.org/wp-content/upload... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://advancedenergyunited.org/wp-content/upload... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (F — 20/100)

*3710ms total JS execution*

- **[WARNING]** https://advancedenergyunited.org/: 1036ms CPU time
- **[WARNING]** https://unpkg.com/gsap@3.12.2/dist/gsap.min.js: 1026ms CPU time
- **[WARNING]** Unattributable: 719ms CPU time
- **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-BSRJ...: 319ms CPU time
- **[WARNING]** https://advancedenergyunited.org/cdn-cgi/challenge...: 282ms CPU time
- **[INFO]** Third-party scripts: 1516ms (41% of total)

### Font Loading (A+ — 100/100)

*3 fonts (185 KB)*

- **[INFO]** 3 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (B — 80/100)

*16 scripts, 94 KB unused*

- **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-BSRJ...: 72 KB unused (41%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://advancedenergyunited.org/wp-includes/js/jq...: 22 KB unused (72%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 94 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)

*No optimization needed*

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

### 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 — 90/100)

*Main HTML max-age=600 (~10min)*

- **[INFO]** Main HTML cached for 10 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+ — 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 (C — 60/100)

*70 resources · 7.9 MB · 94 KB savings available*

- **[WARNING]** Page weight 7.9 MB exceeds 1 MB target by 6.9 MB
- **[INFO]** ~94 KB of savings available
- **[INFO]** 15 third-party resources (5% of weight)
- **[INFO]** 4 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 — 84/100)

*2 JS blocking issue(s) detected*

- **[WARNING]** 2 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 3.7 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]** 23 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+ — 100/100)

*97 links checked, 97 healthy, 0 broken*

- **[PASS]** 97 of 97 links are healthy

### 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+ — 100/100)

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

- **[INFO]** og:title is short (22 characters) — Ideal length is 25–60 characters for social sharing previews.

### Open Graph / Twitter Card Depth (A — 90/100)

*1 OG/Twitter depth issue(s) detected*

- **[INFO]** og:image aspect ratio 6.01:1 (8408×1399) is outside Facebook's recommended ~1.91:1 — Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 8408×1399 give a ratio of 6.01:1, which Facebook will crop center-to-fit; the result often clips important content from the top/bottom or sides. Use a wider/taller image close to 1.91:1, or accept the cropping consequences.

### Structured Data (B — 80/100)

*1 JSON-LD block(s) found — some improvements recommended.*

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

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

*1 JSON-LD block(s) declaring 6 schema type(s)*

- **[PASS]** 6 rich-result schema type(s) declared — Inventory of structured-data types on the page (each may unlock a different SERP feature):

ImageObject, Organization, ReadAction, SearchAction, 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 — 40/100)

*4 issues found across 7 images*

- **[WARNING]** 7 images significantly larger than display size — Resizing to display dimensions could save approximately 863 KB.
- **[WARNING]** 7 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[WARNING]** All 7 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]** 1 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.

### 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+ — 100/100)

*2 A records, 42 ms lookup*

- **[PASS]** Resolves to 2 IPv4 address(es)
- **[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: 42 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)

*0/2 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 141.193.213.11: lookup 141.193.213.11: 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 141.193.213.10: lookup 141.193.213.10: 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 31ms across 3 resolvers (spread 5ms)*

- **[PASS]** Quad9: 29ms
- **[PASS]** Cloudflare: 30ms
- **[PASS]** Google: 34ms

### 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 (A+ — 100/100)

*robots.txt present, sitemap with 17 URLs*

- **[PASS]** robots.txt is present
- **[PASS]** sitemap.xml is present
- **[PASS]** sitemap.xml is valid XML
- **[PASS]** sitemap.xml contains 17 entries
- **[PASS]** Sitemap index with 17 child sitemaps
- **[PASS]** robots.txt references sitemap

### URL Variants (B — 75/100)

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

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
- **[CRITICAL]** HTTP version does not redirect to HTTPS

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

*advancedenergyunited.org — via GoDaddy.com, LLC, 4 years, 4 months old, hosted on Cloudflare*

- **[PASS]** Domain registered until Jun 3, 2027 (8 months remaining)
- **[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: GoDaddy.com, LLC
- **[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: Cloudflare

Required by EU Web Accessibility Directive 2016/2102 for public-sector bodies; recommended best practice elsewhere. Common URLs: /accessibility, /accessibility-statement, /a11y. Detection is by link URL and anchor text, in a limited set of languages, so this is an unconfirmed absence.

### GDPR Article 13 Disclosures (F — 12/100)

*1 / 8 Art. 13 categories matched in homepage body*

- **[WARNING]** GDPR Article 13 disclosure coverage: 1 / 8 categories — Scanned the homepage body text AND the linked /privacy page for GDPR Article 13 disclosures.

### Cross-Site Cookies (SameSite=None) (B — 85/100)

*1 cross-site cookie(s) (1 tracking-shaped, 0 essential)*

- **[INFO]** 1 tracking-shaped cross-site cookie(s): __cf_bm — Cookies with SameSite=None travel in cross-site contexts (third-party iframes, cross-origin POSTs, embedded widgets). With third-party cookies dying in Chrome/Firefox, the legitimate use cases narrowed to SSO + payment widgets + federated auth. Each tracking-shaped cookie surfaced here is a cross-site analytics or ad-tech surface that needs explicit privacy-policy disclosure beyond basic cookie banner consent. Audit each: is it conditional on consent? Does the privacy policy name the recipient + purpose? Switching to SameSite=Lax disables the cross-site travel without breaking same-site analytics.

### Beacon Tracking (sendBeacon) (A+ — 100/100)

*No navigator.sendBeacon usage detected in inline scripts*

- **[PASS]** No navigator.sendBeacon usage detected in inline scripts

*1 input(s) using type=text where a specific type would help*

*1/1 iframe(s) missing title; 0 placeholder(s)*

- **[WARNING]** <iframe> missing title attribute (src="") — WCAG 4.1.2: iframes need a title attribute so screen readers can announce what's embedded. Without one, the announcement is just "iframe" -- the user has no way to decide whether to enter or skip.

### 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

### Sitemap Freshness (C — 70/100)

*Sitemap exists but no <lastmod> entries*

- **[INFO]** Sitemap has no <lastmod> entries — Without lastmod, Google can't tell which URLs have changed since the last crawl -- it falls back to crawling everything periodically.

## Sustainability

### CO2 Per Page Load (F — 30/100)

*1.87g CO2 per view*

- **[WARNING]** 1.87g CO2 per page view — This page transfers 7.9 MB, producing an estimated 1.87g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.05g, network 0.39g, end-user device 1.44g.
- **[INFO]** At 10,000 monthly views: 225.0 kg CO2/year — With 10,000 page views per month, this page would generate approximately 225.0 kg of CO2 annually — equivalent to charging 28124 smartphones.
- **[PASS]** Green hosting reduces data center emissions

### Green Hosting (A — 85/100)

*Green (cdn)*

- **[PASS]** Cloudflare CDN uses renewable energy — Since most traffic is served through the CDN, the majority of data transfer energy is renewable.
- **[INFO]** Cloudflare: 100% renewable energy for global network since 2019
- **[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*

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.
