Screenshots
Top Priorities (5)
8 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
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.
Cross-Origin-Opener-Policy header is missing
COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
External script from analytics.python.org lacks integrity attribute
External resource without SRI — if the third-party CDN is compromised, your site executes attacker-controlled code.
Referrer-Policy has a weak value
Weak Referrer-Policy values leak full URLs (with query params, tokens, IDs) to every third-party resource on the page.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€198 investment → €5,923/month returns + EUR 20,500,000 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
5 barrier(s) likely increasing bounce by ~23%.
- Severe layout shift during page loadUsers mis-click when content jumps — converting intent into frustration→ Reserve space for images, ads, and embeds with explicit width/height
- Page loads in 3.1sEvery additional 100ms above 2.5s costs conversions — you're 623ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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
- 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
15 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
