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
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
Critical: 4

No H1 heading found

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Accessibility › Heading Hierarchy
Warning: 5

69 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
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 13.3s 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.
2 security gaps detected — browsers may warn visitors about your site.
2 accessibility issues exclude users who rely on assistive technology.
Your LCP is 13.3s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

Business case

  • Page takes 13.3s to load
    Users abandon at ~3s — you're 10.8s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • 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
  • 9 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
  • High main-thread blocking time
    Page is non-interactive for 282ms after first paint
    → Defer third-party scripts and split large bundles
  • 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 (Google Code Prettify) 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

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