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

No <main> landmark found

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Accessibility › Landmark Structure
Warning: 4

is missing width/height — may cause layout shift

Performance issues directly impact user engagement and conversion rates.

Performance › Image Optimization
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 18.2s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. The 3 security gaps leave your users exposed — modern browsers increasingly warn visitors about insecure sites. 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 18.2s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

  • Page takes 18.2s to load
    Users abandon at ~3s — you're 15.7s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean
  • No skip-to-content link
    Keyboard and screen-reader users must tab through the entire header on every page
    → Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
  • 2 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

Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (3)

Hosted on GitHub Pages

GitHub Pages provides free static hosting with automatic HTTPS. Limitations: no server-side code, 1GB site size limit, 100GB/month bandwidth.

No build tool detected

A framework (Bootstrap) 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.

Complex technology stack detected

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