Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
Cookie '_qiita_login_session' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
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.
1 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
¥70,000 investment → ¥1,209,145/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
9 barrier(s) likely increasing bounce by ~30%.
- Page takes 11.8s to loadUsers abandon at ~3s — you're 9.3s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 2.3sClicks 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
- Layout shifts during page loadContent movement causes mis-clicks on CTAs and form fields→ Add width/height to images; reserve space for late-loading embeds
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)
No build tool detected
A framework (Amazon Route 53) 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
27 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
