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
Warning: 3

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
Warning: 4

Total JS execution time is 4.9 s -- over the 3.5s budget

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
Warning: 5

Unattributable: 1533ms CPU time

Informational: CPU time spent on this resource. Total >1s is a perf budget violation.

Performance › JS Execution Cost
What fixing these means. Your site is in great shape. The remaining improvements are refinements rather than critical fixes. Your LCP of 5.1s exceeds Google's 2.5s 'Good' threshold and the 2 performance issues below directly contribute 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.
Your LCP is 5.1s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.

Optimistic scenario assuming the top 3 capture most of the upside. Real-world recovery typically falls between this projection and the full-fix ROI above.

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.

  • Page takes 5.1s to load

    → Optimize render-blocking resources, preload the hero image, and compress images
  • 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

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

Observations (2)

No build tool detected

A framework (Django) 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

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