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

3 font preload(s) missing `crossorigin` -- font will be downloaded twice

Performance issues directly impact user engagement and conversion rates.

Performance › Resource Hints
Warning: 4

3 render-blocking <script src> tag(s) without async/defer

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
Warning: 5

4 render-blocking stylesheet(s) -- recommended: <=3

Informational: a Permissions-Policy directive showing feature -> allowed origins.

Performance › CSS Performance Depth
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 4.6s exceeds Google's 2.5s 'Good' threshold and the 3 performance issues below directly contribute to it. Addressing the critical issues below would have the most immediate impact on your user trust.
2 security gaps detected — browsers may warn visitors about your site.
Your LCP is 4.6s — fixing the 3 performance criticals 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.

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 4.6s to load
    Users abandon at ~3s — you're 2.1s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 2.0s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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 structured data
    No rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices
    → Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)

Observations (2)

No build tool detected

A framework (Google Search Console) 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

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