Top Priorities (5)
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
Page weighs 16.0 MB (5.2 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
22 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.
558 third-party resources (100% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
559 HTTP requests — consider bundling or reducing
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
$475 investment → $4,577/month returns + USD 157,500 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
7 barrier(s) likely increasing bounce by ~23%.
- Page feels frozen for 8.0sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 29 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
- Page loads in 3.5sEvery additional 100ms above 2.5s costs conversions — you're 985ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)
No build tool detected
A framework (Backbone.js) 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
24 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
