# BeaverCheck Audit Report — https://aiseomate.com **Date:** July 13, 2026 **URL:** https://aiseomate.com **Overall Grade:** B (80/100) **Report:** https://beavercheck.com/results/5399209e-8bfd-43a6-b4ca-f70ec36bb3d3 ## Top Findings 1. **[CRITICAL]** Content-Security-Policy header is missing — Security > Security Headers 2. **[CRITICAL]** No Content-Security-Policy header found — Security > Content Security Policy 3. **[WARNING]** 31 inline style attribute(s) detected — Security > CSP Inline-Style Readiness 4. **[WARNING]** 43 third-party resources (51% of weight) — Performance > Page Weight Inventory 5. **[WARNING]** Cross-Origin-Embedder-Policy header is missing — Security > Security Headers --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 56 | | Accessibility | 91 | | Best Practices | 100 | | SEO | 100 | --- ## Security ### Security Headers (C — 55/100) *4 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 - **[WARNING]** Referrer-Policy has a weak value - **[PASS]** Permissions-Policy is set - **[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. - **[WARNING]** Server header reveals version information — The Server header discloses the software version, aiding attackers in targeting known vulnerabilities. Remove the version number. - **[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, 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 68 days) - **[PASS]** Certificate chain has 4 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) *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. ### CSP Inline-Style Readiness (C — 75/100) *31 inline style attribute(s) detected* - **[WARNING]** 31 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. 31 inline style(s) is moderate. Affected element types include: img, div, text. 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 ### 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 (D — 50/100) *30% high-risk feature coverage (3/10)* - **[WARNING]** Permissions-Policy covers 3/10 high-risk features (30%) — The Permissions-Policy header explicitly declares policies for 3/10 high-risk features. Covered: camera, microphone, geolocation Not declared (default-allow): payment, usb, serial, midi, accelerometer, gyroscope, magnetometer The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them. ### Referrer-Policy Strictness (D — 50/100) *Referrer-Policy is `origin-when-cross-origin` (leaky -- origin sent cross-origin even on protocol downgrade)* - **[WARNING]** Referrer-Policy: `origin-when-cross-origin` -- leaky -- origin sent cross-origin even on protocol downgrade — Same-origin requests get full URL; cross-origin gets only origin. Similar shape to the modern default BUT does NOT suppress Referer on HTTPS-to-HTTP downgrade -- the origin leaks even when the protocol is downgrading to HTTP. Switch to `strict-origin-when-cross-origin` for the same UX with no downgrade leak. ### 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 (A+ — 100/100) *No external resources* - **[PASS]** No external resources to protect ### 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: google) - **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts. and a policy file at https://mta-sts./.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.. - **[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 (B — 75/100) *3 directives, 2 missing* - **[PASS]** camera=() — blocked for all origins - **[PASS]** microphone=() — blocked for all origins - **[PASS]** geolocation=() — blocked for all origins - **[INFO]** payment not restricted — Consider adding payment=() to block payment access from embedded content. - **[INFO]** usb not restricted — Consider adding usb=() to block usb access from embedded content. ### CORS Configuration (B — 80/100) *No CORS headers* - **[PASS]** No CORS headers present — secure default --- ## Performance ### Page Weight Budget (A — 87/100) *965 KB transferred, 81 requests* - **[PASS]** Page weighs 2.1 MB (965 KB transferred) - **[INFO]** 81 HTTP requests - **[INFO]** Estimated 0.20 g CO2 per page load ### Third-Party Impact (B — 70/100) *51% third-party, 0 ms blocking* - **[WARNING]** Third-party code accounts for 51% of page weight (495.1 KiB of 965.2 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) *27 images, 0 KB saveable* - **[PASS]** All images are well-optimized ### JS Execution Cost (D — 40/100) *2105ms total JS execution* - **[WARNING]** https://www.redditstatic.com/ads/pixel.js: 450ms CPU time - **[WARNING]** https://aiseomate.com/_next/static/chunks/2117-d94...: 396ms CPU time - **[WARNING]** Unattributable: 376ms CPU time - **[WARNING]** https://aiseomate.com/: 350ms CPU time - **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-GX4T...: 314ms CPU time - **[INFO]** Third-party scripts: 764ms (36% of total) ### Font Loading (A+ — 100/100) *1 fonts (47 KB)* - **[INFO]** 1 font(s) use font-display: swap (FOUT risk but functional) ### JS Bundles (B — 80/100) *26 scripts, 68 KB unused* - **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-GX4T...: 68 KB unused (42%) — Consider code splitting or tree shaking to reduce unused code. - **[INFO]** Total unused JavaScript: 68 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) (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 (B — 85/100) *Cache-Control present but without max-age* - **[INFO]** Main HTML Cache-Control has no max-age: s-maxage=31536000, stale-while-revalidate ### 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: RSC, Next-Router-State-Tree, Next-Router-Prefetch, 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]** `ETag` present -- conditional GET supported ### Page Weight Inventory (A — 85/100) *81 resources · 965 KB · 68 KB savings available* - **[PASS]** Within 1MB page-weight target - **[INFO]** ~68 KB of savings available - **[WARNING]** 43 third-party resources (51% of weight) --- ## Infrastructure ### DNS Records (A+ — 95/100) *1 A records, 117 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) - **[PASS]** 3 nameserver(s) configured - **[PASS]** 1 mail exchanger(s) configured - **[PASS]** SPF record present in TXT - **[PASS]** DNS resolution time: 117 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 (B — 75/100) *0/2 IPs match cert SAN* - **[INFO]** PTR for 66.241.124.219 does not match any cert SAN: ip-66-241-124-219.shared.customer.flyio.net — Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree. - **[INFO]** PTR for 2a09:8280:1::8d:6e6c:0 does not match any cert SAN: ipv6.customer.flyio.net — Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree. ### Multi-Resolver DNS Speed (B — 80/100) *Mean 143ms across 3 resolvers (spread 72ms)* - **[PASS]** Google: 107ms - **[PASS]** Quad9: 144ms - **[PASS]** Cloudflare: 179ms ### Redirect Chain (A+ — 100/100) *No redirects — direct access* - **[PASS]** No redirects — direct access ### IPv6 Readiness (A+ — 100/100) *IPv6 reachable (24 ms)* - **[PASS]** IPv6 is configured and reachable at 2a09:8280:1::8d:6e6c:0 ### Crawlability (A+ — 100/100) *robots.txt present, sitemap with 15 URLs* - **[PASS]** robots.txt is present - **[PASS]** sitemap.xml is present - **[PASS]** sitemap.xml is valid XML - **[PASS]** sitemap.xml contains 15 entries - **[PASS]** Sitemap index with 15 child sitemaps - **[PASS]** robots.txt references sitemap ### URL Variants (A — 90/100) *www/non-www, trailing slash, HTTP→HTTPS* - **[PASS]** www/non-www redirect configured correctly (preferred: non-www) - **[WARNING]** HTTP→HTTPS redirect uses 302 instead of 301 ### Domain Intelligence (A+ — 100/100) *aiseomate.com — via DreamHost, LLC, 8 months old* - **[PASS]** Domain registered until Oct 17, 2026 (3 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: DreamHost, 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. --- ## Compliance ### WCAG Compliance (A+ — 100/100) *No testable criteria* ### Cookie Consent & Privacy (B — 80/100) *No consent signals detected* - **[WARNING]** No privacy policy link detected — A privacy policy page is recommended for transparency and may be legally required. - **[INFO]** No terms of service link detected - **[INFO]** No cookie consent banner detected - **[INFO]** This is an automated check, not legal advice — BeaverCheck detects technical indicators of consent management. This does not constitute a legal compliance assessment. Consult a privacy professional for GDPR/CCPA compliance. ### Consent UX Depth (A+ — 100/100) *No consent-UX depth issues detected* - **[PASS]** No consent-UX depth issues detected ### Tracker Inventory (A+ — 100/100) *No script URLs to scan -- tracker inventory is N/A* - **[PASS]** No script URLs to scan -- tracker inventory is N/A ### Language & i18n (A — 90/100) *Lang attribute present* - **[PASS]** attribute is present - **[PASS]** value is valid - **[INFO]** No Content-Language HTTP header - **[INFO]** Language signals are inconsistent — The attribute and Content-Language header should agree. ### Hreflang Configuration (A+ — 100/100) *No hreflang tags on this page* - **[PASS]** No hreflang tags found (single-language site) ### Internationalization Extras (A+ — 100/100) *No HTML captured -- i18n extras check is N/A* - **[PASS]** No HTML captured -- i18n extras check is N/A ### Readability & Typography (A+ — 100/100) *Font sizes and tap targets checked* ### Viewport Configuration (F — 30/100) *No viewport meta tag* - **[CRITICAL]** No viewport meta tag found — Without a viewport meta tag, the page will not render correctly on mobile devices. ### Accessibility Statement (B — 70/100) *No accessibility statement detected* - **[WARNING]** No accessibility statement detected — Sites are increasingly expected to publish an accessibility statement. Required by EU Web Accessibility Directive 2016/2102 for public-sector bodies; recommended best practice elsewhere. Common URLs: /accessibility, /accessibility-statement, /a11y. ### GDPR Article 13 Disclosures (F — 25/100) *0 / 8 Art. 13 categories matched in homepage body* - **[WARNING]** GDPR Article 13 disclosure coverage: 0 / 8 categories — Scanned the homepage body text AND the linked /privacy page for GDPR Article 13 disclosures. Matched 0 of 8 categories: . Missing: . Note: only the FIRST same-origin privacy-policy link is followed; deeper sub-pages (e.g. /legal/data-subject-rights) are not fetched. ### Third-Party Trackers (C — 55/100) *1 trackers detected* - **[INFO]** 1 third-party trackers detected — Found 1 analytics, 0 advertising, 0 marketing, 0 tag manager, 0 session-replay, 0 heatmap trackers. - **[WARNING]** Trackers detected but no cookie policy found — This page loads 1 trackers but no cookie policy was detected. GDPR requires disclosure when using tracking cookies. - **[WARNING]** Trackers detected but no privacy policy found — Most data protection regulations require a privacy policy when collecting user data via trackers. ### Cookie & Tracker Inventory (A+ — 100/100) *0 cookies · 1 trackers · 0 pre-consent* - **[INFO]** 1 third-party tracker(s) detected on page ### Browser Fingerprinting (A+ — 100/100) *No browser-fingerprinting libraries detected* - **[PASS]** No browser-fingerprinting libraries detected ### Cross-Site Cookies (SameSite=None) (A+ — 100/100) *No cookies on the page* - **[PASS]** No cookies set on the page response ### Beacon Tracking (sendBeacon) (A+ — 100/100) *No HTML captured -- beacon-tracking check is N/A* - **[PASS]** No HTML captured -- beacon-tracking check is N/A --- ## 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 (B — 80/100) *s-maxage=31536000, stale-while-revalidate* - **[PASS]** Cache-Control header is set - **[PASS]** CDN TTL: 52 weeks (s-maxage=31536000) - **[PASS]** ETag present — enables conditional (304) responses ### 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 — 90/100) *HTTP/3, HSTS, and TLS version analysis* - **[INFO]** HTTP/3 (QUIC) not advertised — HTTP/3 eliminates head-of-line blocking. If your CDN supports it, consider enabling it. - **[PASS]** HSTS enabled (includeSubDomains, preload) - **[PASS]** HSTS preload enabled - **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT) ### Health Check Endpoint (A+ — 100/100) *Health endpoint at https://aiseomate.com/api/health (HTTP 200)* - **[PASS]** Public health endpoint at https://aiseomate.com/api/health ### 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 ### 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 (A+ — 100/100) *Font-size measurement not available for this scan* - **[PASS]** Font-size measurement not available for this scan --- ## UX ### 404 Error Page (C — 65/100) *HTTP 404, custom page* - **[PASS]** Correct 404 status code returned - **[PASS]** Custom styled 404 page - **[PASS]** Homepage link present on 404 page ### Favicon & Branding (D — 50/100) *5 icon(s) detected* - **[PASS]** favicon.ico present at site root - **[INFO]** No apple-touch-icon detected — iOS devices use this when users add your site to their home screen. Add . - **[PASS]** Multiple icon sizes detected ### Web Manifest (A+ — 100/100) *PWA-ready* - **[PASS]** Meets PWA install criteria - **[PASS]** Name present: AISEOMate - **[PASS]** 192x192 icon present - **[PASS]** 512x512 icon present - **[PASS]** Display mode: standalone ### PWA Depth (A+ — 100/100) *No PWA depth issues detected* - **[PASS]** No PWA depth issues detected ### Dark Mode Support (D — 40/100) *No dark mode signals* - **[INFO]** No dark mode signals detected — Consider adding CSS with @media (prefers-color-scheme: dark) and . - **[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 — 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+ — 100/100) *No HTML captured -- mobile-depth check is N/A* - **[PASS]** No HTML captured -- mobile-depth check is N/A --- ## SEO ### SEO Audit Unavailable *Content probe data missing -- see finding for details* - **[INFO]** SEO checks could not run for this scan — Content probe data is missing for this scan -- SEO checks need the rendered DOM (canonical tag, meta description, hreflang, etc.). Common causes: bot-detection block (Akamai/Cloudflare/Imperva served the worker a challenge instead of the page), worker timeout, or the site redirected to an unrelated host. --- ## Sustainability ### CO2 Per Page Load (A — 85/100) *0.22g CO2 per view* - **[PASS]** 0.22g CO2 per page view — This page transfers 0.9 MB, producing an estimated 0.22g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.01g, network 0.05g, end-user device 0.17g. - **[INFO]** At 10,000 monthly views: 26.8 kg CO2/year — With 10,000 page views per month, this page would generate approximately 26.8 kg of CO2 annually — equivalent to charging 3346 smartphones. - **[PASS]** Green hosting reduces data center emissions ### Green Hosting (B — 80/100) *Green (hosting)* - **[PASS]** Fly.io uses renewable energy - **[INFO]** Fly.io: Carbon offsets for all compute - **[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 33 KB (vs 965 KB first visit). 80 of 81 resources are served from browser cache, saving 0.22g CO2 per repeat visit. - **[INFO]** Repeat visit: 0.01g CO2 (first visit: 0.22g) ### Carbon Budget (A — 85/100) *12th percentile* - **[PASS]** 0.22g CO2 — below the sustainability target of 0.50g — Cleaner than an estimated 88% of websites analyzed. This page meets the Web Sustainability Guidelines target. - **[INFO]** Estimated 12th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view. ### Transfer Efficiency (A+ — 100/100) *93% efficient* - **[PASS]** Transfer efficiency: 93% — Only 68 KB of potential savings identified. Your page is well-optimized for size. --- --- *Generated by [BeaverCheck](https://beavercheck.com) — https://beavercheck.com/results/5399209e-8bfd-43a6-b4ca-f70ec36bb3d3*
