Screenshots
Top Priorities (5)
3 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
80 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.
External script from cmp.springernature.com lacks integrity attribute
External resource without SRI — if the third-party CDN is compromised, your site executes attacker-controlled code.
External script from idp_shim.sciam.com lacks integrity attribute
External resource without SRI — if the third-party CDN is compromised, your site executes attacker-controlled code.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€213 investment → €11,081/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
6 barrier(s) likely increasing bounce by ~24%.
- Page takes 6.5s to loadUsers abandon at ~3s — you're 4.0s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- High main-thread blocking timePage is non-interactive for 316ms after first paint→ Defer third-party scripts and split large bundles
- 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
- 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
14 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
