## Security

### Security Headers (F — 10/100)

*2 of 10 headers properly configured*

- **[CRITICAL]** HSTS header is missing — Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
- **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
- **[WARNING]** X-Frame-Options has unexpected value
- **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis.
- **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[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 1.2, 7 checks passed*

- **[PASS]** TLS 1.2 is used
- **[INFO]** TLS 1.3 is not negotiated — TLS 1.3 offers improved performance and security. Consider enabling it.
- **[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 128 days)
- **[PASS]** Certificate chain has 2 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 100 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 (D — 60/100)

*13 of 13 new-tab link(s) missing rel=noopener*

- **[WARNING]** 13 link(s) open in a new tab without rel=noopener — Without rel="noopener", the destination tab can navigate the original tab via window.opener -- a reverse-tabnabbing phishing primitive. Modern browsers default to noopener since Chrome 88 / Firefox 79 / Safari 12.1, but explicit rel="noopener noreferrer" remains the documented best practice for older browsers, in-app webviews, and security scanners.

### CSP Inline-Style Readiness (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: form, input, button, div, img. 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 (B — 75/100)

*Referrer-Policy header not set -- browser default applies (modern: strict-origin-when-cross-origin; legacy browsers: no-referrer-when-downgrade)*

- **[INFO]** Referrer-Policy header not set -- browser default applies — Without an explicit `Referrer-Policy` header, the browser falls back to its default policy. Modern browsers (Chrome 85+, Firefox 87+, Safari 15+) default to `strict-origin-when-cross-origin`, which is privacy-safe. Legacy browsers default to the leaky `no-referrer-when-downgrade`, which sends the full URL (including path + query) on cross-origin HTTPS-to-HTTPS requests. Set an explicit header to ensure consistent behavior:

```
Referrer-Policy: strict-origin-when-cross-origin
```

This matches the modern browser default and is privacy-safe without breaking referrer-based same-origin analytics.

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

*No source maps accessible (probed 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 (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 (F — 0/100)

*no DMARC, no SPF*

- **[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.
- **[WARNING]** No SPF record found — Without SPF (Sender Policy Framework), receivers can't tell which servers are authorized to send mail for your domain. Add a TXT record at the apex starting with v=spf1, ending in -all.
- **[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 (F — 0/100)

*32.6 MB transferred, 96 requests*

- **[CRITICAL]** Page weighs 33.2 MB (32.6 MB transferred)
- **[WARNING]** Images are 32.4 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[INFO]** 96 HTTP requests
- **[INFO]** Estimated 6.8 g CO2 per page load

### Third-Party Impact (A+ — 100/100)

*No third-party resources*

- **[PASS]** No third-party resources detected

### Text Compression (A+ — 100/100)

*All text resources are compressed*

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

### Image Optimization (C — 60/100)

### JS Execution Cost (F — 20/100)

*4561ms total JS execution*

- **[WARNING]** Unattributable: 2729ms CPU time
- **[WARNING]** https://www.econ.sdu.edu.cn/: 1052ms CPU time
- **[WARNING]** https://www.econ.sdu.edu.cn/js/swiper.min.js: 613ms CPU time
- **[INFO]** https://www.econ.sdu.edu.cn/js/a_jquery.js: 168ms CPU time

### Font Loading (A+ — 100/100)

*No web fonts (system fonts)*

- **[PASS]** No web fonts loaded — system fonts are fastest

### JS Bundles (A+ — 100/100)

*15 scripts, 25 KB unused*

- **[WARNING]** https://www.econ.sdu.edu.cn/js/swiper.min.js: 25 KB unused (88%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 25 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 — 90/100)

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

- **[INFO]** Main HTML cached for 10 minutes -- mild staleness risk

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

*No Server-Timing header found*

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

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

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: Accept-Encoding — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[PASS]** Both `ETag` and `Last-Modified` present -- efficient revalidation supported — The page returns both `ETag` (content hash) and `Last-Modified` (timestamp) headers. Browsers can issue conditional GETs with `If-None-Match` or `If-Modified-Since`; the server returns 304 Not Modified for unchanged content, saving bandwidth. ETag is the more reliable of the two (timestamps fail in DST transitions and clock skew).

### Page Weight Inventory (C — 60/100)

*96 resources · 32.6 MB · 25 KB savings available*

- **[WARNING]** Page weight 32.6 MB exceeds 1 MB target by 31.6 MB
- **[INFO]** 18 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 — 70/100)

*2 JS blocking issue(s) detected*

- **[WARNING]** 16 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 4.6 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]** 5 render-blocking stylesheet(s) -- recommended: <=3 — Each `<link rel="stylesheet">` without a non-blocking `media` attribute holds up the first paint. Browsers download all of them before painting any content. Consolidate into 1-2 critical-path stylesheets; defer non-critical CSS via `<link rel="stylesheet" media="print" onload="this.media='all'">` or via the loadCSS pattern; inline above-the-fold CSS in `<style>` to short-circuit the request entirely.

---

## Content Quality

### Links (A+ — 100/100)

*195 links checked, 195 healthy, 0 broken*

- **[PASS]** 195 of 195 links are healthy

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (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 (F — 25/100)

*7 issues found across 72 images*

- **[WARNING]** 27 images significantly larger than display size — Resizing to display dimensions could save approximately 30431 KB.
- **[WARNING]** 72 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 65 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 72 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]** Total image weight: 50255 KB (49.1 MB) — Consider compressing images, using modern formats, and serving appropriately sized images.
- **[INFO]** 10 image(s) wider than 400px without srcset (no responsive serving) — These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://www.econ.sdu.edu.cn/images/9ce9f6fe8b25f13836b46b7849ee2cf0.jpg, https://www.econ.sdu.edu.cn/images/abd60f700598ca3ae829311df3875f13.jpg, https://www.econ.sdu.edu.cn/images/huanying2026xintongxue.png (+7 more).
- **[INFO]** 4 image(s) rendered at a different aspect ratio than the source — The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://www.econ.sdu.edu.cn/__local/E/B8/E5/C1E74CB98D6846F2C15DD1846A9_D9AF41F6_A25DF.png, https://www.econ.sdu.edu.cn/__local/C/06/53/8928C7FF81CF4C9ED3BA6C55439_21550289_5ADCC.png, https://www.econ.sdu.edu.cn/__local/6/61/1A/CB9188E109C7DA542125CC0EA3F_4D370C10_CFD8C.jpg (+1 more).

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

## Infrastructure

### DNS Records (C — 65/100)

*1 A records, 235 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
- **[INFO]** No SPF record found in TXT records — SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.
- **[WARNING]** DNS resolution is slow (235 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]** 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 (C — 60/100)

*0/2 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 202.194.15.159: lookup 202.194.15.159: no such host — No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.
- **[INFO]** PTR lookup failed for 2001:da8:7000:15:202:194:15:159: lookup 2001:da8:7000:15:202:194:15:159: 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 (C — 65/100)

*Mean 190ms across 3 resolvers (spread 240ms)*

- **[PASS]** Google: 79ms
- **[PASS]** Cloudflare: 174ms
- **[PASS]** Quad9: 319ms
- **[INFO]** High latency spread between resolvers: 240ms (min 79ms / max 319ms) — 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.

### Viewport Configuration (C — 60/100)

*Viewport prevents zooming*

- **[PASS]** Viewport meta tag is present
- **[PASS]** width=device-width is set
- **[CRITICAL]** Viewport prevents user zooming — user-scalable=no or maximum-scale < 2 prevents users from zooming. This is a WCAG 1.4.4 (Level AA) failure and an accessibility barrier for users with low vision.

### 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.

### Copyright Notice (C — 55/100)

*No copyright notice detected*

- **[INFO]** No copyright notice detected — No copyright notice detected in the page content. While not legally required in most jurisdictions (copyright exists automatically), a notice is standard practice and signals site ownership.

### 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.

### Compliance Badges (C — 55/100)

---

## 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 (A+ — 100/100)

*max-age=600 (10 minutes)*

- **[PASS]** Cache-Control header is set
- **[PASS]** Effective TTL: 10 minutes (max-age=600)
- **[PASS]** ETag present — enables conditional (304) responses
- **[PASS]** Last-Modified header present

### 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 (B — 75/100)

*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.
- **[WARNING]** Missing Strict-Transport-Security header — HSTS tells browsers to only use HTTPS, preventing SSL stripping attacks.

### 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 — 50/100)

*7 landmarks*

- **[CRITICAL]** No <main> landmark found — Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
- **[PASS]** 3 <nav> landmark(s) found
- **[WARNING]** 3 of 3 <nav> elements are unlabeled — Multiple navigations need aria-label to distinguish them for screen readers.
- **[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 (F — 0/100)

*61 headings, 24 skip(s)*

- **[CRITICAL]** No H1 heading found — Every page should have one H1 that describes the page content.
- **[WARNING]** Heading level skipped: H3 → H5 (missing H4) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
- **[WARNING]** Heading level skipped: H3 → H5 (missing H4) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
- **[WARNING]** Heading level skipped: H3 → H5 (missing H4) — Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

- **[WARNING]** 3 empty heading(s) — Empty headings appear in the document outline but provide no information.

### Heading Text Quality (A — 85/100)

*2 heading-text-quality issue(s) detected*

- **[INFO]** 1 heading(s) are too short (≤2 characters) to convey meaning — Headings with 2 or fewer characters are almost always emoji / typos / alignment hacks rather than real headings. Screen readers announce the heading level ("heading 2") and then read the content -- a single-character heading conveys no information. Affected:
  - H3: "首页"
- **[INFO]** 41 heading(s) are all-uppercase (excluding short acronyms) — Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.

### Alt Text Quality (A+ — 100/100)

*All 72 images OK*

- **[PASS]** 72 decorative image(s) correctly marked

### Form Accessibility (C — 55/100)

*3 of 3 controls have issues*

- **[CRITICAL]** 3 control(s) without accessible label — Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

### Link & Button Quality (F — 28/100)

*23 issue(s) across 293 links and 2 buttons*

- **[CRITICAL]** 21 link(s) with no accessible text — Links without text are announced as raw URLs by screen readers.
- **[CRITICAL]** 1 image-only link(s) without alt text — Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.
- **[WARNING]** 70 link(s) open in new tab without warning — Add '(opens in new tab)' to link text or aria-label.
- **[CRITICAL]** 2 button(s) with no accessible text — Icon-only buttons need an aria-label so screen readers can announce them.
- **[PASS]** 201 link(s) with descriptive text

### Form Input Types (A+ — 100/100)

*3 form control(s) checked, no type mismatches*

- **[PASS]** No input-type mismatches detected

### Form Input Quality (A+ — 100/100)

*3 form control(s) checked, no input-semantic issues*

- **[PASS]** All form input semantics look correct

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

*No autofill-eligible form controls*

- **[PASS]** No autofill-eligible form controls (no name/email/tel/address fields)

### Document Language (F — 40/100)

*Missing <html lang> attribute (WCAG 3.1.1)*

- **[CRITICAL]** Missing <html lang> attribute (WCAG 3.1.1) — Without `<html lang="...">`, screen readers default to the user's system language even when reading content in a different one -- words get pronounced wrong (English text read with French phonetics, etc.). Add a BCP-47 language tag to the <html> root element.

### Tabindex Anti-Patterns (A+ — 100/100)

*No explicit tabindex attributes found*

- **[PASS]** No explicit tabindex attributes found

### Iframe Accessibility (A+ — 100/100)

*No iframes on this page*

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

### 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 (B — 90/100)

*97% of visible text renders at >= 12 CSS px (1 below threshold)*

- **[INFO]** 1 text node(s) render below 12 CSS pixels on mobile — Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <div> 10.5px ("8月30日，经济学院、经济研究院召开2026年秋季学期务虚会，聚焦立德树人根本任...").

## UX

### 404 Error Page (C — 55/100)

*HTTP 404, custom page*

- **[PASS]** Correct 404 status code returned
- **[PASS]** Custom styled 404 page

### Favicon & Branding (F — 15/100)

*1 icon(s) detected*

- **[WARNING]** No favicon.ico at site root — Some older browsers, bookmark tools, and RSS readers look for /favicon.ico. Add one as a fallback.
- **[PASS]** HTML icon links detected
- **[INFO]** No apple-touch-icon detected — iOS devices use this when users add your site to their home screen. Add <link rel='apple-touch-icon' sizes='180x180' href='/apple-touch-icon.png'>.

### Web Manifest (D — 40/100)

*Not found*

- **[INFO]** No web manifest found — No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

### 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 <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 — 15/100)

*No navigation patterns*

- **[PASS]** 3 navigation landmark(s) detected
- **[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)

*2 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. Adding a single hex color in `<meta name="theme-color" content="#0066cc">` tints them to your brand color across all mobile browsers.
- **[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.

## SEO

### Canonical URL (B — 80/100)

*Minor issues*

- **[WARNING]** No canonical tag found — Search engines will determine the canonical URL themselves, which may cause duplicate content issues.

### Meta Tags (B — 75/100)

*Title: 24 chars*

- **[PASS]** Page title is set
- **[WARNING]** Title is only 24 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

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

### Sitemap Freshness (C — 75/100)

*No sitemap.xml found*

- **[INFO]** No sitemap.xml found — Sitemaps help search engines discover and prioritize URLs. Not strictly required for small sites where every page is linked from the homepage, but recommended once a site grows beyond a few dozen URLs.

### Sitemap × Robots Consistency (C — 75/100)

*Sitemap or robots.txt missing -- consistency check skipped*

- **[INFO]** Cross-check skipped (sitemap or robots.txt absent)

## Sustainability

### CO2 Per Page Load (F — 15/100)

*9.23g CO2 per view*

- **[CRITICAL]** 9.23g CO2 per page view — This page transfers 32.6 MB, producing an estimated 9.23g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 1.71g, network 1.59g, end-user device 5.92g.
- **[INFO]** At 10,000 monthly views: 1107.3 kg CO2/year — With 10,000 page views per month, this page would generate approximately 1107.3 kg of CO2 annually — equivalent to charging 138411 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)

*100% cached*

- **[PASS]** 100% reduction on repeat visits — Returning visitors download only 21 KB (vs 33364 KB first visit). 95 of 96 resources are served from browser cache, saving 9.22g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.01g CO2 (first visit: 9.23g)

### Carbon Budget (F — 15/100)

*95th percentile*

- **[WARNING]** 9.23g CO2 — above the median website (0.60g) — Heavier than an estimated 5% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 95th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (A+ — 100/100)

*100% efficient*

- **[PASS]** Transfer efficiency: 100% — Only 25 KB of potential savings identified. Your page is well-optimized for size.

### 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.
