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

Page weighs 10.2 MB (5.3 MB transferred)

Informational: total page weight (uncompressed) and bytes actually transferred over the wire.

Performance › Page Weight Budget
Critical: 4

39 image-only link(s) without alt text

Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.

Accessibility › Link & Button Quality
Warning: 5

178 HTTP requests — consider bundling or reducing

High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

Performance › Page Weight Budget
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 8.2s 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.
2 security gaps detected — browsers may warn visitors about your site.
Your LCP is 8.2s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.
1 accessibility issue excludes users who rely on assistive technology.

Business case

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

  • Page takes 8.2s to load
    Users abandon at ~3s — you're 5.7s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 607ms
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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
  • Layout shifts during page load
    Content movement causes mis-clicks on CTAs and form fields
    → Add width/height to images; reserve space for late-loading embeds

Observations (2)

No build tool detected

A framework (Amazon Route 53) 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.
