## Security

### Security Headers (F — 25/100)

*2 of 10 headers properly configured*

- **[WARNING]** HSTS max-age is too short (15552000s, should be ≥ 31536000s) — A short max-age leaves a window for downgrade attacks. Set max-age to at least 31536000 (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.
- **[INFO]** Cross-Origin-Opener-Policy is set but not 'same-origin'
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[PASS]** X-Powered-By header is not present
- **[PASS]** Server header is not present
- **[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 — 90/100)

*TLS 1.3, 7 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.
- **[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 7 days)
- **[WARNING]** Certificate expires soon (7 days remaining) — Renew the certificate before it expires to avoid browser warnings.
- **[PASS]** Certificate chain has 2 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 11 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*No cookies set — no cookie security risks*

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

### Cookie Hygiene (A+ — 100/100)

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

- **[PASS]** No cookies set

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

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

### security.txt (A+ — 100/100)

*Vulnerability disclosure policy*

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

### Cross-Origin Tab Safety (A+ — 100/100)

*All 4 new-tab link(s) carry rel=noopener*

- **[PASS]** All 4 new-tab link(s) carry rel=noopener

### CSP Inline-Style Readiness (B — 90/100)

*8 inline style attribute(s) detected*

- **[INFO]** 8 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. 8 inline style(s) is low. Affected element types include: span, label, div. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win.

### Trusted Types (XSS Sink Hardening) (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)

*HTTP status is non-2xx -- soft-404 check is N/A*

- **[PASS]** HTTP status is non-2xx -- soft-404 check is N/A

### 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 (0/13 third-party resources)*

- **[WARNING]** SRI adoption: 0/13 third-party resources protected (0%) — Of 13 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.xx.fbcdn.net/rsrc.php/v5/yn/l/0,cross/lpWUp9vbP3MhFUXNXFoJRR7TF2-QXH5TPT9DWDYPz6DhfgQe914iiBfvP3p6y_S61oONMKn3YhINqU49pVNahkCkvx2I9b7Pb8K.css
  - https://static.xx.fbcdn.net/rsrc.php/v4/yD/r/IPmdhgOiFnE.js
  - https://static.xx.fbcdn.net/rsrc.php/v4/yC/r/aNpX5S5aB2J2qgvuYi1BODA5myf85rzWQL09OiSCsDJPv_kkAv_-wGQgXdYivvCwsHLSF6kN-2Goi2GUdvRYOtepfAozIMNFBkkxElsDJ_KC4Nw1JtOGoHMq05SYinLq4Fklu4yAsukPWHDS8r_-bqsbSWsVjQqltBeBhusk2amyJhKMh2otzgdunJl3g9q4pR78qL69VqNNp4Gm1BHl-lElGzTH4Lah-t55E7mOl6Gkjq0OVeavkZc4HIHnCJZCcc2ZP1Mq8wypiAW_bfk-AMUuK2ufRhAdmh5DEndjkC1LYw5WWi7IP1HIUYBqZ4h.js
  - https://static.xx.fbcdn.net/rsrc.php/v4ieWv4/yc/l/en_GB-j/OasyqiG0T1Z.js
  - https://static.xx.fbcdn.net/rsrc.php/v4iOUW4/yl/l/en_GB-j/FzSXdE2zMDn.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)

*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 (B — 90/100)

*2 link(s) carry redirect-shaped query parameter(s)*

- **[INFO]** 2 link(s) carry redirect-shaped query parameter(s) — Heuristic flag -- whether each endpoint actually permits an arbitrary redirect target depends on server-side validation. Audit the listed paths' redirect-target handling: the endpoint should either (a) restrict to a relative path, (b) restrict to an allowlisted host set, or (c) sign the target. Open redirects power phishing flows (the attacker's URL begins with your trusted domain) and bypass some SSRF-mitigation cookie scoping. Common parameter names flagged: redirect, redirect_uri, redirect_url, redirecturl, return, returnto, return_to, returnurl, return_url, next, nexturl, next_url, continue, goto, dest, destination, forward, target.

### Auth Security (A — 85/100)

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

- **[PASS]** Login page detected — The page contains a `type=password` input and at least one identifier field (username / email). Auth-security findings below evaluate the page's hardening posture.
- **[WARNING]** Login form does not contain a recognizable CSRF token — Standard frameworks emit CSRF tokens as a hidden input named `_csrf`, `csrf_token`, `csrfmiddlewaretoken` (Django), `authenticity_token` (Rails), or `__RequestVerificationToken` (ASP.NET). None of those were found. Possibilities: (1) the form posts to an API that uses a custom header or SameSite cookie reliance for CSRF -- legitimate but not visible from this scan, (2) the form is genuinely missing CSRF protection, which would let an attacker submit logins from another origin via a hidden POST. Verify the auth flow has SOME CSRF defense.

### 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 13 external resources have SRI*

- **[WARNING]** External link from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.xx.fbcdn.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from static.xx.fbcdn.net 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 (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 (A — 88/100)

*927 KB transferred, 56 requests*

- **[PASS]** Page weighs 2.8 MB (927 KB transferred)
- **[WARNING]** JavaScript is 645 KB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** Fonts are 201 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[INFO]** 56 HTTP requests
- **[INFO]** Estimated 0.19 g CO2 per page load

### Third-Party Impact (D — 50/100)

*99% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 99% of page weight (922.0 KiB of 927.2 KiB)
- **[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)

*7 images, 0 KB saveable*

- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/yh/r/iXKR... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/yS/r/kHeV... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/ys/r/lBaB... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/yU/r/0gFm... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (C — 60/100)

*1923ms total JS execution*

- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4/yu/r/M...: 511ms CPU time
- **[WARNING]** https://m.facebook.com/unified/login_via/app/?next...: 501ms CPU time
- **[WARNING]** Unattributable: 443ms CPU time
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4/y0/r/B...: 325ms CPU time
- **[INFO]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4iLl54/y...: 84ms CPU time
- **[WARNING]** Third-party scripts: 1480ms (77% of total)

### Font Loading (A+ — 100/100)

*2 fonts (201 KB)*

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

### JS Bundles (C — 60/100)

*19 scripts, 222 KB unused*

- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4/yu/r/M...: 150 KB unused (58%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4iczx4/y...: 38 KB unused (74%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://z-m-static.xx.fbcdn.net/rsrc.php/v4/y0/r/B...: 34 KB unused (48%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 222 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+ — 95/100)

*13 hints, 0 missing preconnects*

- **[INFO]** 1 URL(s) appear in multiple hints — The same href shouldn't appear in multiple hint rels -- one wins, the others are wasted markup and may confuse cache behavior. Sample: https://static.xx.fbcdn.net/rsrc.php/v5/yk/l/0,cross/NL1DOtqAsKMwCrB0Y6jo2v.css (preload+preload).
- **[PASS]** Page uses 13 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.

### Compression Algorithm (C — 70/100)

*Main response served uncompressed*

- **[INFO]** Main HTML response has no Content-Encoding (uncompressed) — The main HTML document is served without compression. The Text Compression section above lists the broader picture; for the main response specifically, even gzip would shave ~70-80% off most text payloads.

### 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 (A+ — 100/100)

*9 Server-Timing entries advertised*

- **[PASS]** Server-Timing header advertises 9 timing entries

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

*1 server-response signal(s) detected*

- **[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 (B — 80/100)

*56 resources · 927 KB · 222 KB savings available*

- **[PASS]** Within 1MB page-weight target
- **[INFO]** ~222 KB of savings available
- **[WARNING]** 55 third-party resources (99% 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 — 80/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** 15 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 — 96/100)

*41 links checked, 39 healthy, 0 broken*

- **[PASS]** 39 of 41 links are healthy
- **[INFO]** Long redirect chain: https://www.facebook.com/about/ (4 hops)
- **[INFO]** Long redirect chain: https://www.facebook.com/ad_campaign/landing.ph... (3 hops)

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (F — 0/100)

*No Open Graph tags found — social sharing previews will be generic.*

- **[WARNING]** No Open Graph meta tags found — Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

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

*No OG image or Twitter card set -- depth check is N/A (presence covered by Open Graph section)*

- **[PASS]** No OG image / Twitter card to evaluate

### 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 (A+ — 100/100)

*No images to analyze*


### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

---

## Infrastructure

### DNS Records (B — 80/100)

*1 A records, 42 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.
- **[PASS]** Has 1 IPv6 (AAAA) record(s)
- **[WARNING]** CNAME record at zone apex — A CNAME at the zone apex can break MX and NS records. Use ALIAS/ANAME or A records instead.
- **[INFO]** No NS records found
- **[INFO]** No MX records — email not configured via DNS
- **[PASS]** SPF record present in TXT
- **[PASS]** DNS resolution time: 42 ms

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** CNAME does not point at a known takeover-able service

### 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 (A+ — 100/100)

*2/2 IPs match cert SAN*

- **[PASS]** PTR for 157.240.202.35 matches certificate SAN: edge-star-mini-shv-02-cdg4.facebook.com
- **[PASS]** PTR for 2a03:2880:f17b:187:face:b00c:0:25de matches certificate SAN: edge-star-mini6-shv-02-cdg4.facebook.com

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

*Mean 13ms across 3 resolvers (spread 22ms)*

## Availability

### CDN & Delivery (D — 50/100)

*No CDN detected*

- **[WARNING]** No CDN detected — A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (F — 30/100)

*No cache headers*

- **[WARNING]** No Cache-Control header found — Browsers will use heuristic caching, which can be unpredictable. Set explicit cache headers.

### 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]** HSTS max-age is short: 180 days — HSTS max-age should be at least 1 year (31536000 seconds).
- **[INFO]** HSTS missing includeSubDomains — Without includeSubDomains, HSTS only protects the exact domain.
- **[PASS]** HSTS preload enabled
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### 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 (C — 65/100)

*1 landmarks*

- **[PASS]** <main> landmark present
- **[WARNING]** No <nav> landmark found
- **[INFO]** No banner (header) landmark
- **[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 — 80/100)

*No headings*

- **[WARNING]** No headings found — Headings (H1-H6) create the document outline for screen reader navigation.

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

- **[PASS]** No images on this page

### Form Accessibility (A — 85/100)

*1 of 3 controls have issues*

- **[PASS]** 29 link(s) with descriptive text

### Form Input Types (A+ — 95/100)

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

- **[INFO]** Input "email" should use type="email" (currently type="text") — Field name "email" suggests type="email". Wrong type loses mobile keyboard hints, browser autofill, and free format validation. Change to <input type="email">.

### Form Input Quality (B — 82/100)

*2 input-semantic issue(s) across 3 form control(s)*

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

### Mobile Keyboard & Autofill (A+ — 100/100)

*All 1 eligible field(s) carry autocomplete/inputmode*

### Dark Mode Support (B — 70/100)

### 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 — 0/100)

*No navigation patterns*

- **[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+ — 97/100)

*1 mobile-depth signal(s) detected*

- **[INFO]** No `<meta name="theme-color">` -- browser chrome falls back to default — Without `theme-color`, Android Chrome's status bar and iOS Safari's toolbar fall back to a generic gray.

## SEO

### Canonical URL (B — 75/100)

*Minor issues*

- **[PASS]** Canonical tag present
- **[WARNING]** Canonical does not match final URL (https://www.facebook.com/login/?next=https%3A%2F%2Fwww.facebook.com%2F61591775755857)
- **[PASS]** Canonical target returns 200
- **[INFO]** Canonical points to a different domain
- **[WARNING]** Canonical www-ness doesn't match the final URL — Either the canonical has 'www.' and the final URL doesn't, or vice versa. Search engines may index both forms as duplicates. Pick one and use it consistently in the canonical AND the redirect target.

### Meta Tags (B — 75/100)

*Title: 8 chars*

- **[PASS]** Page title is set
- **[WARNING]** Title is only 8 characters — consider expanding
- **[WARNING]** No meta description tag found — Without a meta description, Google auto-generates a snippet from page content -- usually less click-attractive than a hand-written summary. Add `<meta name="description" content="...">` with a 70-160 char summary.

### Title Style Depth (A+ — 100/100)

*Title style is clean -- consistent separator, no stale year, no keyword stuffing*

- **[PASS]** Title style is clean

### Content Depth (F — 25/100)

*70 words, Very Difficult*

- **[WARNING]** Page has 70 words — thin content — Most well-ranking pages have 300+ words of substantive content.
- **[INFO]** Text-to-HTML ratio is 0% — Very low ratio suggests heavy framework overhead or boilerplate.
- **[INFO]** Reading level: Very Difficult (grade 32)

*No hreflang tags on this page -- check is N/A (single-language site or unannotated)*

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

### 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. Adding lastmod (date or ISO 8601 timestamp) on each <url> entry signals freshness so the crawler prioritizes recently-modified pages.

### Sitemap × Robots Consistency (A+ — 100/100)

*No sitemap-vs-robots conflicts detected*

- **[PASS]** Sitemap URLs are not blocked by robots.txt

### Sitemap Hygiene (B — 75/100)

*1 hygiene issue(s) on a 0-URL sitemap*

- **[WARNING]** Sitemap is empty -- 0 URLs listed — The sitemap file is reachable and parses as valid XML, but contains no `<url>` entries. Common causes: a templated sitemap that didn't iterate the URL set during build, a static placeholder shipped to production, or a CMS that lost its URL index. Search engines fetch and discard empty sitemaps.

### Markup Quality (A — 90/100)

*1 markup-quality issue(s) detected*

- **[WARNING]** No `<meta charset>` declaration in HTML — The page has no `<meta charset="...">` tag. Browsers fall back to a default encoding (typically UTF-8 in modern browsers, but not guaranteed). Add `<meta charset="utf-8">` as the first child of `<head>` to make the encoding explicit.

## Sustainability

### CO2 Per Page Load (A — 85/100)

*0.26g CO2 per view*

- **[PASS]** 0.26g CO2 per page view — This page transfers 0.9 MB, producing an estimated 0.26g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.05g, network 0.04g, end-user device 0.16g.
- **[INFO]** At 10,000 monthly views: 30.8 kg CO2/year — With 10,000 page views per month, this page would generate approximately 30.8 kg of CO2 annually — equivalent to charging 3846 smartphones.

### Green Hosting (D — 50/100)

*Unknown*

- **[INFO]** Hosting provider could not be identified — Without knowing the provider, we cannot determine their energy sourcing. Check with your hosting provider about their renewable energy commitments.
- **[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)

*95% cached*

- **[PASS]** 95% reduction on repeat visits — Returning visitors download only 47 KB (vs 927 KB first visit). 54 of 56 resources are served from browser cache, saving 0.24g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.01g CO2 (first visit: 0.26g)

### Carbon Budget (A — 85/100)

### Transfer Efficiency (B — 80/100)

*76% efficient*

- **[INFO]** Transfer efficiency: 76% — An estimated 222 KB (24%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 222 KB of unused JavaScript. This wasted data produces 0.06g of unnecessary CO2 per page view.

### Web Font Weight Variants (B — 90/100)

*No detectable Google Fonts weights*

- **[INFO]** No detectable Google Fonts weights — The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
