Top Priorities (5)

Sorted by impact
Critical: 1

'unsafe-inline' found in script source

Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.

Security › Content Security Policy
Critical: 2

2 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: 3

No <main> landmark found

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Accessibility › Landmark Structure
Warning: 4

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

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
Warning: 5

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

Performance issues directly impact user engagement and conversion rates.

Performance › Resource Hints
What fixing these means. Your site is in great shape. The remaining improvements are refinements rather than critical fixes. Your LCP of 3.1s 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.
1 security gap detected — browsers may warn visitors about your site.
2 accessibility issues exclude users who rely on assistive technology.
Your LCP is 3.1s — fixing the 2 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.

  • Page feels frozen for 704ms
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • Page loads in 3.1s
    Every additional 100ms above 2.5s costs conversions — you're 640ms over
    → Target <2.5s LCP: defer non-critical scripts and optimize the hero image
  • 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
  • 2 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
  • No Open Graph tags
    Links shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop
    → Add og:title, og:description, og:image, og:url to the page head

Observations (2)

No build tool detected

A framework (HSTS) 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

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