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.
1 render-blocking <script src> tag(s) without async/defer
Performance issues directly impact user engagement and conversion rates.
137 third-party resources (97% 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.

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
6 barrier(s) likely increasing bounce by ~27%.
- Page takes 19.4s to loadUsers abandon at ~3s — you're 16.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 6.4sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 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, …)
- Content is hard to readGraduate-level reading difficulty — limits the addressable audience for product or blog pages→ Shorten sentences; replace jargon with plain language; target Flesch ease ≥60

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
23 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
