Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
1 control(s) without accessible label
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
2 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.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.

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.
Conversion barriers
9 barrier(s) likely increasing bounce by ~31%.
- Page takes 4.3s to loadUsers abandon at ~3s — you're 1.8s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 797msClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher 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 labelScreen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes→ Associate every input with a visible <label for="…">; add autocomplete attributes

Observations (5)
jQuery loaded alongside a modern framework
Both jQuery and React are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
No build tool detected
A framework (Bootstrap) 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.
React version may be outdated
Detected React 6.3.1. The current major version is 18. Consider updating for security patches and new features.
jQuery version may be outdated
Detected jQuery 1.8.3. The current major version is 3. Consider updating for security patches and new features.
Complex technology stack detected
21 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
