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 14.9 MB (5.8 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
1 control(s) without accessible label
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
16 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.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
¥68,000 investment → ¥1,398,335/month returns + JPY 100,000,000 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
10 barrier(s) likely increasing bounce by ~38%.
- 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 7.9sClicks 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">
- 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.
