Top Priorities (5)
Page weighs 7.7 MB (4.2 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
1 link(s) with no accessible text
Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.
15 third-party resources (79% 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.
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.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
£131 investment → £5,270/month returns + GBP 18,050,000 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 ~24%.
- Page takes 13.0s to loadUsers abandon at ~3s — you're 10.5s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 2.5sClicks 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, …)
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)
No build tool detected
A framework (Azure Front Door) 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.
