Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
Page weighs 22.6 MB (5.9 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
2 image(s) missing alt attribute
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.
6 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€680 investment → €8,169/month returns + EUR 120,500,000 risk avoided
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
7 barrier(s) likely increasing bounce by ~30%.
- Page takes 8.1s to loadUsers abandon at ~3s — you're 5.6s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 14.0sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 92 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
- 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.
