Top Priorities (5)
Page weighs 41.3 MB (40.6 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
6 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
114 HTTP requests — consider bundling or reducing
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.
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
HKD 3,163 investment → HKD 50,114/month returns
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
8 barrier(s) likely increasing bounce by ~33%.
- Page takes 84.4s to loadUsers abandon at ~3s — you're 81.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 872msClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 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
- 12 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (3)
No build tool detected
A framework (AOS) 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.
Bootstrap version may be outdated
Detected Bootstrap 4.5.0. The current major version is 5. Consider updating for security patches and new features.
Complex technology stack detected
14 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
