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.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
51 third-party resources (100% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Cross-Origin-Embedder-Policy header is missing
COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€573 investment → €5,947/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 ~27%.
- Page takes 16.6s to loadUsers abandon at ~3s — you're 14.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- 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 structured dataNo rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices→ Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)
- Thin contentUnder 300 words — visitors bounce looking for substance, search engines rank competitors first→ Add a substantive FAQ, product detail, or case-study section
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Complex technology stack detected
18 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
