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.
Soft 404: server returns HTTP 200 for non-existent pages
Soft 404s (HTTP 200 for missing pages) confuse Google — it indexes the 'not found' page as real content and ranks it.
14 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
£563 investment → £3,126/month returns + GBP 17,500,000 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 ~14%.
- Page loads in 2.6sEvery additional 100ms above 2.5s costs conversions — you're 102ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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

How this is calculated
Based on Google/Deloitte research ("Milliseconds Make Millions") showing a ~7% bounce rate increase per additional second of LCP above the 2.5s "Good" threshold.

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