Top Priorities (5)
Page weighs 5.8 MB (4.1 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
18 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
120 HTTP requests — consider bundling or reducing
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.
18 inline style attribute(s) detected
Inline style attributes force `style-src 'unsafe-inline'` in any CSP -- effectively negating CSP's XSS-mitigation value for stylesheets.
4 render-blocking stylesheet(s) -- recommended: <=3
Informational: a Permissions-Policy directive showing feature -> allowed origins.
Business case

Return on investment

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 11.9s to loadUsers abandon at ~3s — you're 9.4s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 1.6sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- Viewport disables user zoomVisitors with low vision can't read the page — and some jurisdictions treat this as a legal risk→ Remove user-scalable=no; drop maximum-scale if it's below 2
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)
No build tool detected
A framework (Bulma) 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.
