Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

No Content-Security-Policy header found

Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

Security › Content Security Policy
Warning: 3

55 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: 4

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
Warning: 5

Cross-Origin-Opener-Policy header is missing

COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.

Security › Security Headers
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 15.8s 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 15.8s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

  • Page takes 15.8s to load
    Users abandon at ~3s — you're 13.3s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 2.3s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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
  • No structured data
    No rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices
    → Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)
  • 2 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

Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (2)

No build tool detected

A framework (Apple) 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

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