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.
1 render-blocking <script src> tag(s) without async/defer
Performance issues directly impact user engagement and conversion rates.
16 inline style attribute(s) detected
Inline style attributes force `style-src 'unsafe-inline'` in any CSP -- effectively negating CSP's XSS-mitigation value for stylesheets.
5 third-party resources (58% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€1,020 investment → €5,283/month returns + EUR 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
4 barrier(s) likely increasing bounce by ~12%.
- Page loads in 3.5sEvery additional 100ms above 2.5s costs conversions — you're 968ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)
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.
Complex technology stack detected
10 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
