Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

No Content-Security-Policy header found

Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

Security › Content Security Policy
Critical: 3

Soft 404: server returns HTTP 200 for non-existent pages

Soft 404s (HTTP 200 for missing pages) confuse Google — it indexes the 'not found' page as real content and ranks it.

Accessibility › 404 Error Page
Warning: 4

37 third-party resources (100% of weight)

Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.

Performance › Page Weight Inventory
Warning: 5

Cross-Origin-Embedder-Policy header is missing

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Security › Security Headers
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 8.0s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Addressing the critical issues below would have the most immediate impact on your user trust.
3 security gaps detected — browsers may warn visitors about your site.
1 accessibility issue excludes users who rely on assistive technology.
Your LCP is 8.0s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

Business case

What fixing the audit's findings is worth -- and what ignoring them keeps costing.

  • Page takes 8.0s to load

    → Optimize render-blocking resources, preload the hero image, and compress images
  • Severe layout shift during page load
    Users mis-click when content jumps — converting intent into frustration
    → Reserve space for images, ads, and embeds with explicit width/height
  • 6 broken link(s) on the page
    Clicks land on 404s — trust drops and the session often ends
    → Fix or remove the broken destinations surfaced on the Content tab
  • High main-thread blocking time
    Page is non-interactive for 563ms after first paint
    → Defer third-party scripts and split large bundles
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains

Observations (3)

No build tool detected

A framework (Azure DNS) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Bootstrap version may be outdated

Detected Bootstrap 4.6.2. The current major version is 5. Consider updating for security patches and new features.

→ Security

Complex technology stack detected

16 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
