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

3 link(s) with no accessible text

Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.

Accessibility › Link & Button Quality
Critical: 4

9 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
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. 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.
2 accessibility issues exclude users who rely on assistive technology.

  • Page takes 14.3s to load

  • Page feels frozen for 1.7s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 9 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
  • 5 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
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
