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
Warning: 2

is missing width/height — may cause layout shift

Performance issues directly impact user engagement and conversion rates.

Performance › Image Optimization
Warning: 3

34 third-party resources (54% 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: 4

Cookie 'XSRF-TOKEN' is missing the HttpOnly flag

Without HttpOnly, JavaScript can read the cookie — an XSS bug becomes a session-stealing attack.

Security › Cookie Security
Warning: 5

Cross-Origin-Embedder-Policy header is missing

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Security › Security Headers
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 11.0s 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.
3 security gaps detected — browsers may warn visitors about your site.
Your LCP is 11.0s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.

Business case

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 11.0s to load
    Users abandon at ~3s — you're 8.5s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 721ms
    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
  • 4 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
