## Security

### Security Headers (C — 55/100)

*5 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured
- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured
- **[PASS]** Referrer-Policy is properly configured
- **[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
- **[PASS]** Domain is in the Chrome HSTS preload list (status: preloaded)

### 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
- **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance.
- **[PASS]** OCSP stapling enabled
- **[PASS]** Certificate is valid (expires in 99 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 2 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*No cookies set — no cookie security risks*

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

### Cookie Hygiene (A+ — 100/100)

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

- **[PASS]** No cookies set

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

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

### security.txt (A — 85/100)

*Vulnerability disclosure policy*

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

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

*15 of 24 new-tab link(s) missing rel=noopener*

- **[WARNING]** 15 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 (D — 60/100)

*59 inline style attribute(s) detected*

- **[WARNING]** 59 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. 59 inline style(s) is high. Affected element types include: div, svg. 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 (F — 30/100)

*0% SRI adoption (0/9 third-party resources)*

- **[WARNING]** SRI adoption: 0/9 third-party resources protected (0%) — Of 9 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://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/css/449d1c8b46ef0e03.css
  - https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/css/9260f8b8cef76175.css
  - https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/css/3f976cabfbb0f462.css
  - https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/chunks/52774a7f-971f6d93da707a26.js
  - https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/chunks/4bd1b696-354e29b8fceb5553.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 (A+ — 100/100)

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

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

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

*Source-map probe didn't run on this scan*

- **[PASS]** Source-map probe didn't run on this scan

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

*No software-version disclosures in HTML*

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

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

*No redirect-shaped query parameters in DOM links*

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

### Auth Security (A+ — 100/100)

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

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

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

*No risky subdomain names in certificate SANs*

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

- **[WARNING]** External link from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.nubank.com.br lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.

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

*No known vulnerabilities*

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

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

*No exposures*

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

### Email Security (A+ — 98/100)

*DMARC: reject, SPF: -all, DKIM, BIMI*

- **[PASS]** DMARC policy is reject — strongest protection
- **[PASS]** SPF ends in -all (hard fail) — strongest setting
- **[PASS]** DKIM configured (selectors: mailgun, mandrill, google, k1, s2, s1)
- **[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 — 16/100)

*3.4 MB transferred, 138 requests*

- **[WARNING]** Page weighs 10.3 MB (3.4 MB transferred)
- **[WARNING]** JavaScript is 2.5 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** Fonts are 345 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[WARNING]** 138 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 (D — 50/100)

*97% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 97% of page weight (3.3 MiB of 3.4 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 (B — 75/100)

*29 images, 0 KB saveable*

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

### JS Execution Cost (F — 20/100)

*37837ms total JS execution*

- **[WARNING]** https://static.nubank.com.br/17a5d9c7cc870ad93ba9f...: 22454ms CPU time
- **[WARNING]** https://nubank.com.br/: 6737ms CPU time
- **[WARNING]** Unattributable: 2075ms CPU time
- **[WARNING]** https://static.nubank.com.br/17a5d9c7cc870ad93ba9f...: 724ms CPU time
- **[WARNING]** https://www.googletagmanager.com/gtm.js?id=GTM-KGF...: 639ms CPU time
- **[WARNING]** Third-party scripts: 29025ms (77% of total)

### Font Loading (A+ — 100/100)

*9 fonts (345 KB)*

- **[INFO]** 9 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (F — 20/100)

*51 scripts, 961 KB unused*

- **[WARNING]** https://static.nubank.com.br/17a5d9c7cc870ad93ba9f...: 125 KB unused (65%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://static.nubank.com.br/17a5d9c7cc870ad93ba9f...: 78 KB unused (36%) — Consider code splitting or tree shaking to reduce unused code.

- **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-LQFL...: 69 KB unused (38%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.googletagmanager.com/gtm.js?id=GTM-T2J...: 65 KB unused (42%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 961 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 — 85/100)

*11 hints, 0 missing preconnects*

- **[WARNING]** 9 font preload(s) missing `crossorigin` -- font will be downloaded twice — Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/media/36256e370bf6e286-s.p.woff2, https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/media/60a2f104238a90af-s.p.woff2, https://static.nubank.com.br/17a5d9c7cc870ad93ba9f958fb7cb827793f07e7/_next/static/media/64a06134aa18a255-s.p.woff2 (+6 more). Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
- **[PASS]** Page uses 11 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.

### Compression Algorithm (B — 80/100)

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

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

### 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 max-age=0 (≤ 5min) is appropriate*

- **[PASS]** Main HTML max-age=0 (≤ 5min) is appropriate

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

*No Server-Timing header found*

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

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

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: rsc,Accept-Encoding — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[INFO]** No `ETag` or `Last-Modified` -- conditional GET not supported — Without either header, browsers can't issue conditional GETs and refresh always re-downloads the full response body even when nothing changed. Add `ETag: "<hash>"` (or `Last-Modified: <date>`) on cacheable responses; the server returns 304 Not Modified when the client's cached copy is still valid, saving bandwidth.

### Page Weight Inventory (F — 25/100)

*138 resources · 3.4 MB · 961 KB savings available*

- **[WARNING]** Page weight 3.4 MB exceeds 1 MB target by 2.4 MB
- **[INFO]** ~961 KB of savings available
- **[WARNING]** 137 third-party resources (97% of weight)
- **[INFO]** 1 resources over 200KB

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

*No render-blocking resources detected*

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

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

*No third-party resources detected*


### JavaScript Blocking (B — 84/100)

*2 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.
- **[WARNING]** Total JS execution time is 37.8 s -- over the 3.5s budget — Total JavaScript execution (parse + compile + run) across all scripts exceeds 3.5 seconds. On low-end devices that becomes 7-15+ seconds and shows up directly in TBT and INP. Reduce by: tree-shaking unused dependencies, code-splitting (dynamic `import()`), removing or deferring third-party tracking, and replacing heavy frameworks where they're not needed.

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

*No CSS performance depth issues detected*

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

---

## Content Quality

### Links (A+ — 100/100)

*76 links checked, 76 healthy, 0 broken*

- **[PASS]** 76 of 76 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.*


### 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 (C — 40/100)

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

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

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

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

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

### Image Optimization (F — 35/100)

*7 issues found across 17 images*

- **[WARNING]** 5 images significantly larger than display size — Resizing to display dimensions could save approximately 279 KB.
- **[WARNING]** 13 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.
- **[INFO]** 9 of 17 images use legacy formats
- **[WARNING]** 4 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[INFO]** 4 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://www.datocms-assets.com/120597/1754405239-mulher-cafeteria-pagando-com-cartao-nubank_1920x1080.jpg?auto=format&crop=focalpoint&dpr=1&fit=crop&w=2000&q=60, https://www.datocms-assets.com/120597/1718985255-render-cartoes-nubank-ultravioleta-ptbr-caroussel-app-home.webp?auto=format&crop=focalpoint&dpr=1&fit=crop&q=60, https://www.datocms-assets.com/120597/1718985210-render-cartoes-nubank-pj-ptbr-caroussel-app-home.webp?auto=format&crop=focalpoint&dpr=1&fit=crop&q=60 (+1 more).
- **[INFO]** 7 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://www.datocms-assets.com/120597/1754405239-mulher-cafeteria-pagando-com-cartao-nubank_1920x1080.jpg?auto=format&crop=focalpoint&dpr=1&fit=crop&w=2000&q=60, https://www.datocms-assets.com/120597/1746711835-mulher-e-um-homem-sorrindo-na-mesa-ptbr-carousel-segments-mobile.jpg?auto=format&crop=focalpoint&dpr=1&fit=crop&q=60, https://www.datocms-assets.com/120597/1779140962-foto18_still-nubank0319_web_rgb_0424-1.png?auto=format&crop=focalpoint&dpr=1&fit=crop&q=60 (+4 more).

- **[PASS]** 5 media element(s) found, none autoplay

---

## Infrastructure

### DNS Records (A+ — 100/100)

*4 A records, 16 ms lookup*

- **[PASS]** Resolves to 4 IPv4 address(es)
- **[INFO]** No IPv6 (AAAA) records
- **[PASS]** 4 nameserver(s) configured

*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 (A+ — 100/100)

### Tracking Pixel Inventory (C — 75/100)

*4 tracking pixel(s) on the page*

- **[WARNING]** 4 tracking pixel(s) on the page (4 domain(s)) — Tracking pixels are 1x1 / 2x2 cross-origin <img> tags that fire a GET request when the browser renders them -- no JavaScript, no cookies needed. They're how trackers survive when users disable JS or block third-party cookies, and they bypass most ad-blocker rules that target script src. Each one needs explicit disclosure under GDPR Art 7 / CCPA / ePrivacy because the request itself transmits the page URL + IP + user-agent + referrer to the tracker. Audit each surfaced domain: is it disclosed in your privacy policy? Is it conditional on the cookie banner? Affected domains: analytics.twitter.com, pixel.mathtag.com, t.co, t.teads.tv.

*0.95g CO2 per view*

- **[INFO]** 0.95g CO2 per page view — This page transfers 3.4 MB, producing an estimated 0.95g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.18g, network 0.16g, end-user device 0.61g.
- **[INFO]** At 10,000 monthly views: 114.5 kg CO2/year — With 10,000 page views per month, this page would generate approximately 114.5 kg of CO2 annually — equivalent to charging 14317 smartphones.

### Green Hosting (D — 40/100)

*Not green*

- **[INFO]** AWS: Renewable energy varies by region; committed to 100% by 2025
- **[INFO]** AWS CloudFront: Renewable varies by edge location
- **[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)

*97% cached*

- **[PASS]** 97% reduction on repeat visits — Returning visitors download only 104 KB (vs 3451 KB first visit). 135 of 138 resources are served from browser cache, saving 0.93g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.03g CO2 (first visit: 0.95g)

### Carbon Budget (D — 50/100)

*60th percentile*

- **[WARNING]** 0.95g CO2 — above the median website (0.60g) — Heavier than an estimated 40% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 60th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (C — 60/100)

*72% efficient*

- **[WARNING]** Transfer efficiency: 72% — An estimated 961 KB (28%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 961 KB of unused JavaScript. This wasted data produces 0.27g 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).
