Top Priorities (5)
Cookie 'cart_currency' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
Cookie 'localization' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
Page weighs 12.4 MB (7.7 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
2 image(s) missing alt attribute
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.
7 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.

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 ~27%.
- Page takes 14.0s to loadUsers abandon at ~3s — you're 11.5s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 3.1sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 5 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
- HSTS is enabled but max-age is short (7889238s)First-visit protection is in place, but browsers forget the policy sooner than recommended→ Raise Strict-Transport-Security max-age to at least 31536000 (1 year)
- 8 link(s) with generic text ("click here", "read more")Screen-reader users navigating by link list see no context — and search engines can't infer relevance→ Rewrite with descriptive phrases that identify the destination
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (5)
Shopify storefront detected
Shopify handles hosting, SSL, and CDN automatically. Performance optimizations focus on theme code, app scripts, and image optimization. Check the Performance tab for third-party script impact.
jQuery loaded alongside a modern framework
Both jQuery and React are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
No build tool detected
A framework (Azure Edge Network) 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.
jQuery version may be outdated
Detected jQuery 1.11.0. The current major version is 3. Consider updating for security patches and new features.
Complex technology stack detected
19 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
