Top Priorities (5)

Sorted by impact
Critical: 1

Cookie 'ADID' 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.

Security › Cookie Security
Critical: 2

Page weighs 12.0 MB (4.1 MB transferred)

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

Performance › Page Weight Budget
Critical: 3

1 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

80 third-party resources (99% 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

Cookie 'ADID' has no SameSite attribute

Without SameSite, cookies ride along on cross-site requests — enabling CSRF attacks that SameSite=Lax blocks for free.

Security › Cookie Security
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 17.7s exceeds Google's 2.5s 'Good' threshold and the 2 performance issues below directly contribute to it. Addressing the critical issues below would have the most immediate impact on your user trust.
2 security gaps detected — browsers may warn visitors about your site.
Your LCP is 17.7s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.
1 accessibility issue excludes users who rely on assistive technology.

Business case

What fixing the audit's findings is worth -- and what ignoring them keeps costing.

Optimistic scenario assuming the top 3 capture most of the upside. Real-world recovery typically falls between this projection and the full-fix ROI above.

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.

  • Page takes 17.7s to load
    Users abandon at ~3s — you're 15.2s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 1.9s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • Severe layout shift during page load
    Users mis-click when content jumps — converting intent into frustration
    → Reserve space for images, ads, and embeds with explicit width/height
  • 3 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
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains

Observations (2)

No build tool detected

A framework (Amazon Route 53) 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

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