Cookie '_shopify_s' 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.

What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 14.7s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Addressing the critical issues below would have the most immediate impact on your user trust.
4 security gaps detected — browsers may warn visitors about your site.
Your LCP is 14.7s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

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 14.7s to load
    Users abandon at ~3s — you're 12.2s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • 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
  • 53 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
  • 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
