Top Priorities (5)

Sorted by impact
Critical: 1

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers
Critical: 2

Page weighs 14.4 MB (4.0 MB transferred)

Informational: total page weight (uncompressed) and bytes actually transferred over the wire.

Performance › Page Weight Budget
Critical: 3

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.

Accessibility › Link & Button Quality
Warning: 4

548 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.

Performance › Page Weight Inventory
Warning: 5

549 HTTP requests — consider bundling or reducing

High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

Performance › Page Weight Budget
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 3.4s exceeds Google's 2.5s 'Good' threshold and the 3 performance issues below directly contribute to it. Accessibility issues exclude users who rely on assistive technology — an estimated 15% of your potential audience. Addressing the critical issues below would have the most immediate impact on your user trust.
1 security gap detected — browsers may warn visitors about your site.
Your LCP is 3.4s — fixing the 3 performance criticals could bring it under Google's 2.5s 'Good' threshold.
1 accessibility issue excludes users who rely on assistive technology.

  • Page feels frozen for 6.4s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 41 broken link(s) on the page
    Clicks land on 404s — trust drops and the session often ends
    → Fix or remove the broken destinations surfaced on the Content tab
  • Page loads in 3.4s
    Every additional 100ms above 2.5s costs conversions — you're 916ms over
    → Target <2.5s LCP: defer non-critical scripts and optimize the hero image
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean

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

22 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
