Top Priorities (5)
9 publicly-accessible JavaScript source map(s)
Source maps reveal original source code (variable names, comments, file structure) and are shipped to production by mistake almost universally. The standard fix is a one-line build-tool config change.
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.
No favicon or icon links detected
Without a favicon, your tab shows a blank icon and bookmarks look unbranded — amateur signal in every browser surface.
143 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.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
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
6 barrier(s) likely increasing bounce by ~23%.
- Page takes 12.4s to loadUsers abandon at ~3s — you're 9.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- High main-thread blocking timePage is non-interactive for 258ms after first paint→ Defer third-party scripts and split large bundles
- 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)
- 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
- 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.

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.
No build tool detected
A framework (HSTS) 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.
