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 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
18 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
10 barrier(s) likely increasing bounce by ~40%.
- Page takes 17.3s to loadUsers abandon at ~3s — you're 14.8s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 1.7sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- No viewport meta tagMobile browsers render at desktop width and shrink — text unreadable, tap targets miniature→ Add <meta name="viewport" content="width=device-width, initial-scale=1">
- 7 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
