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 11.6 MB (5.6 MB transferred)

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

Performance › Page Weight Budget
Critical: 4

1 control(s) without accessible label

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

Accessibility › Form Accessibility
Critical: 5

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
What fixing these means. Your site has several issues that may be affecting user experience and business outcomes. Your LCP of 23.5s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Accessibility issues exclude users who rely on assistive technology — an estimated 15% of your potential audience. 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 23.5s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.
2 accessibility issues exclude users who rely on assistive technology.

  • Page takes 23.5s to load
    Users abandon at ~3s — you're 21.0s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 1.5s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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
  • 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
  • 1 form field(s) without a label
    Screen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes
    → Associate every input with a visible <label for="…">; add autocomplete attributes

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

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