## Security

### Security Headers (F — 35/100)

*3 of 10 headers properly configured*

- **[WARNING]** HSTS is missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP.
- **[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.
- **[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.
- **[PASS]** X-Powered-By header is not present
- **[PASS]** Server header is present without version info
- **[INFO]** Domain is not in the Chrome HSTS preload list (status: unknown) — Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload).

### Content Security Policy (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 116 days)
- **[PASS]** Certificate chain has 2 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 21 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*No cookies set — no cookie security risks*

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

### Cookie Hygiene (A+ — 100/100)

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

- **[PASS]** No cookies set

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

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

### security.txt (C — 60/100)

*No security.txt file found*

- **[INFO]** No security.txt file found — security.txt (RFC 9116) provides a standardized way for security researchers to report vulnerabilities. Create one at /.well-known/security.txt with at least a Contact field.

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

*No new-tab links found -- no tabnabbing surface*

- **[PASS]** No new-tab links present

### CSP Inline-Style Readiness (D — 60/100)

*291 inline style attribute(s) detected*

- **[WARNING]** 291 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. 291 inline style(s) is high. Affected element types include: img, div, span. 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 (A+ — 100/100)

*Page has no third-party scripts or stylesheets -- SRI not applicable*

- **[PASS]** No third-party scripts or stylesheets to protect with SRI

### 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 (D — 50/100)

*Referrer-Policy is `no-referrer-when-downgrade` (leaky -- legacy default that sends full URL cross-origin on HTTPS-to-HTTPS)*

- **[WARNING]** Referrer-Policy: `no-referrer-when-downgrade` -- leaky -- legacy default that sends full URL cross-origin on HTTPS-to-HTTPS — The legacy browser default (Chrome <85, Firefox <87). Sends the full URL (path + query) Referer on cross-origin requests as long as the protocol doesn't downgrade. This means session IDs, tracking tokens, search queries, etc. embedded in URLs leak to every third-party HTTPS origin the page links to or embeds. Switch to `strict-origin-when-cross-origin`.

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

*No source maps accessible (probed 10 candidate URL(s))*

- **[PASS]** No source maps accessible across 10 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 (B — 90/100)

*2 risky subdomain name(s) in certificate SANs*

- **[INFO]** 2 risky subdomain name(s) advertised in certificate SANs — These names are publicly visible via Certificate Transparency logs (crt.sh, censys.io) -- any attacker can enumerate them in seconds. Operators are often unaware that internal/staging/admin endpoints are inadvertently advertised this way. Mitigation: use a wildcard cert that doesn't enumerate, issue per-environment certs without non-prod SANs on the prod cert, or move internal services to private DNS off the public cert.

## 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 (D — 52/100)

*DMARC: none, SPF: ~all, DKIM*

- **[WARNING]** DMARC policy is none — monitoring only — This only monitors, it doesn't block spoofed emails. Change to p=quarantine or p=reject after monitoring DMARC reports.
- **[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: mail, pm)
- **[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)

*6.5 MB transferred, 247 requests*

- **[CRITICAL]** Page weighs 15.0 MB (6.5 MB transferred)
- **[WARNING]** JavaScript is 2.6 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[WARNING]** Images are 1.9 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[INFO]** Fonts are 601 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[WARNING]** 247 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 1.4 g CO2 per page load

### Third-Party Impact (D — 50/100)

*64% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 64% of page weight (4.2 MiB of 6.5 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (B — 75/100)

*68 images, 0 KB saveable*

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

### JS Execution Cost (F — 20/100)

*10738ms total JS execution*

- **[WARNING]** https://avilon.ru/_next/static/chunks/6353-48a0545...: 5603ms CPU time
- **[WARNING]** https://avilon.ru/: 1512ms CPU time
- **[WARNING]** Unattributable: 1315ms CPU time
- **[WARNING]** https://avilon.ru/_next/static/chunks/4bd1b696-a89...: 292ms CPU time
- **[WARNING]** https://mod.calltouch.ru/front/widget.js?version=f...: 290ms CPU time
- **[INFO]** Third-party scripts: 1820ms (17% of total)

### Font Loading (A+ — 100/100)

*7 fonts (601 KB)*

- **[INFO]** 7 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (F — 20/100)

*66 scripts, 704 KB unused*

- **[WARNING]** https://avilon.ru/_next/static/chunks/8772-7cccb23...: 170 KB unused (93%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://avilon.webim.ru/js/button.js: 128 KB unused (60%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://api.s.mindbox.ru/scripts/modules/webpush.j...: 121 KB unused (73%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://mod.calltouch.ru/front/widget.js?version=f...: 98 KB unused (59%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://web-static.s.mindbox.ru/js/byendpoint/avil...: 70 KB unused (35%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 704 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)

*4 hints, 0 missing preconnects*

- **[WARNING]** 3 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: /_next/static/media/9f946c3bfd005698-s.p.ttf, /_next/static/media/e2fd72c390c50b55-s.p.ttf, /_next/static/media/eb5d8667c55dd7e2-s.p.ttf. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
- **[PASS]** Page uses 4 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 uses no-store -- correct for sensitive/dynamic content*

- **[PASS]** Main HTML uses no-store -- correct for sensitive/dynamic content

### 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: 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 — 30/100)

*247 resources · 6.5 MB · 704 KB savings available*

- **[WARNING]** Page weight 6.5 MB exceeds 1 MB target by 5.5 MB
- **[INFO]** ~704 KB of savings available
- **[WARNING]** 146 third-party resources (64% 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]** 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 10.7 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]** 17 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 — 95/100)

*200 links checked, 199 healthy, 1 broken*

- **[WARNING]** 199 of 200 links are healthy
- **[WARNING]** Broken link: https://avilon.ru/ru-RU/ — Found in <link href>. Returns HTTP 404.

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (A — 90/100)

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

- **[CRITICAL]** og:image is not reachable — The og:image URL could not be fetched. Social platforms won't be able to display it.
- **[INFO]** og:title is long (89 characters) — Titles over 60 characters may be truncated in social sharing previews.
- **[INFO]** og:description is long (206 characters) — Descriptions over 200 characters may be truncated in social sharing previews.

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

*OG image dimensions and Twitter card configuration look healthy*

- **[PASS]** OG/Twitter Card depth is clean -- dimensions, card type, and inheritance all valid

### Structured Data (A+ — 100/100)

*1 JSON-LD block(s) found — structured data is well configured.*

- **[INFO]** Missing recommended property "sameAs" for Organization — Adding "sameAs" can improve how search engines display your content.

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

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

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

Organization

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 — 45/100)

*5 issues found across 200 images*

- **[WARNING]** 44 images significantly larger than display size — Resizing to display dimensions could save approximately 0 KB.
- **[WARNING]** All 178 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]** 6 above-fold image(s) marked loading="lazy" (LCP anti-pattern) — Above-fold images marked lazy delay LCP -- the browser waits for the IntersectionObserver to fire before fetching, even though the image is in the initial viewport. Remove `loading="lazy"` on above-the-fold images (especially the LCP candidate). Sample: https://avilon.ru/png/webLogo.png, https://avilon.ru/svg/call.svg, https://avilon.ru/svg/compare.svg (+3 more).
- **[INFO]** 1 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://s1.avilon.ru/upload/medialibrary/72e/72e58f8a0c64d29515bd26b4244dd915.jpg.
- **[INFO]** 10 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://s1.avilon.ru/upload/medialibrary/72e/72e58f8a0c64d29515bd26b4244dd915.jpg, https://s1.avilon.ru/upload/medialibrary/1e3/1e3f1b2002c5a86894ed3bbcdae19fb3.jpg, https://s1.avilon.ru/upload/medialibrary/9e6/9e67f52d7e2743ea8c9f893ed75f42c0.jpg (+7 more).

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

---

## Infrastructure

### DNS Records (A — 85/100)

*1 A records, 318 ms lookup*

- **[PASS]** Resolves to 1 IPv4 address(es)
- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[INFO]** No IPv6 (AAAA) records
- **[PASS]** 5 nameserver(s) configured
- **[PASS]** 2 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[WARNING]** DNS resolution is slow (318 ms) — Slow DNS adds latency to every page load. Consider a faster DNS provider.

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** No CNAME record present

### DNSSEC (B — 80/100)

*Unsigned (DNSSEC not deployed)*

- **[INFO]** DNSSEC is not deployed — The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

### CAA Records (B — 80/100)

*No CAA records (any CA may issue certificates)*

- **[INFO]** No CAA records published — Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

### Reverse DNS (C — 60/100)

*0/1 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 178.248.232.102: lookup 178.248.232.102: 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 (D — 50/100)

*Mean 264ms across 3 resolvers (spread 549ms)*

- **[PASS]** Google: 65ms
- **[PASS]** Cloudflare: 114ms
- **[PASS]** Quad9: 614ms
- **[INFO]** High latency spread between resolvers: 549ms (min 65ms / max 614ms) — Wide gap between the fastest and slowest public resolver suggests a geographic anycast issue or an authoritative-server cache problem. Users in different regions will see materially different DNS times.

### 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 (A+ — 100/100)

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

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
- **[PASS]** HTTP correctly 301-redirects to HTTPS

### Domain Intelligence (A — 90/100)

*avilon.ru — via RU-CENTER-RU, 24 years, 1 months old, hosted on HLL-AS, RU*

- **[WARNING]** Domain expires in 89 days — Consider enabling auto-renewal to prevent accidental expiration.

*2 hreflang issue(s) across 1 tag(s)*

- **[INFO]** No `x-default` hreflang tag — Google recommends including `<link rel="alternate" hreflang="x-default" href="...">` so search engines have a fallback URL for users whose language / region doesn't match any specific hreflang entry. Typically points to a language-selection page or your default locale.
- **[WARNING]** Hreflang cluster missing self-reference — This page (https://avilon.ru/) appears in no hreflang entry on itself. Per Google's spec, each page in a hreflang cluster must include its own URL with the appropriate hreflang code -- otherwise the cluster is incomplete and search engines may not index alternates correctly.

### Regulatory Indicators

*0 regulatory indicator(s) detected*

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

### Third-Party Data Sharing

*0 third-party service(s) detected*

- **[INFO]** Data inventory for transparency purposes — This inventory identifies third-party services that receive data from your site visitors. Under regulations like GDPR (Article 30), maintaining records of data processing activities is commonly considered a best practice. This automated scan provides a starting point — it may not capture all data flows.
- **[INFO]** No recognized third-party data-sharing services detected — This page does not appear to load external tracking, analytics, or advertising scripts.

---

## 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 (D — 40/100)

*no-store (uncacheable)*

- **[INFO]** Cache-Control: no-store prevents all caching — Intentional for dynamic content, but increases server load for every page view.
- **[INFO]** No ETag or Last-Modified header — Conditional requests (304 Not Modified) are not possible without validators.

### 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 (base policy)
- **[INFO]** HSTS missing includeSubDomains — Without includeSubDomains, HSTS only protects the exact domain.
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### Health Check Endpoint (B — 80/100)

*No conventional health endpoint found*

- **[INFO]** No conventional health endpoint found — Health endpoints (/health, /healthz, /status, /ping, /api/health) let uptime monitors, load balancers, and orchestration systems (Kubernetes, ECS, Fly.io) verify the service is alive. Marketing sites and small services often skip them legitimately; flagged as Info, not a failure. Probe results: /api/health: 404, /health: 404, /healthz: 404, /ping: 404, /status: 404.

### CDN Cache Observability (B — 85/100)

*No CDN cache-status headers in the response*

- **[INFO]** No CDN cache-status headers in the response — Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.

## Accessibility

### Landmark Structure (D — 40/100)

*No landmarks*

- **[CRITICAL]** No <main> landmark found — Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
- **[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 (A — 85/100)

*8 headings, 1 skip(s)*

- **[PASS]** Single H1 present

*No PWA depth issues detected*

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

### Dark Mode Support (D — 45/100)

*Theme color only*

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

### Print Stylesheet (D — 40/100)

*No print styles*

- **[INFO]** No print-specific styles detected — When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

### Navigation UX (F — 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)

*2 mobile-depth signal(s) detected*

- **[PASS]** Browser-chrome `theme-color` meta tag present — The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.
- **[INFO]** iOS auto-link for phone numbers disabled (`format-detection: telephone=no`) — The page sets `<meta name="format-detection" content="telephone=no">`, which prevents iOS Safari from auto-converting phone-number-shaped strings into clickable `tel:` links. Common reason: the auto-detection rewrites mid-paragraph DOM and breaks CSS selectors / JS that depended on the specific text. If you want clickable phone numbers, declare them with explicit `<a href="tel:+1234567890">` and keep auto-detection disabled.

## Sustainability

### CO2 Per Page Load (F — 30/100)

*1.85g CO2 per view*

- **[WARNING]** 1.85g CO2 per page view — This page transfers 6.5 MB, producing an estimated 1.85g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.34g, network 0.32g, end-user device 1.19g.
- **[INFO]** At 10,000 monthly views: 221.5 kg CO2/year — With 10,000 page views per month, this page would generate approximately 221.5 kg of CO2 annually — equivalent to charging 27690 smartphones.

### Green Hosting (D — 40/100)

*Not green*

- **[INFO]** No confirmed renewable energy commitment detected — Consider providers like Cloudflare, Google Cloud, or Vercel that match 100% of their energy use with renewables.
- **[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 181 KB (vs 6674 KB first visit). 242 of 247 resources are served from browser cache, saving 1.80g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.05g CO2 (first visit: 1.85g)

### Carbon Budget (F — 30/100)

*85th percentile*

- **[WARNING]** 1.85g CO2 — above the median website (0.60g) — Heavier than an estimated 15% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 85th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (B — 80/100)

*89% efficient*

- **[INFO]** Transfer efficiency: 89% — An estimated 703 KB (11%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 703 KB of unused JavaScript. This wasted data produces 0.19g 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.
