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

Page weighs 23.1 MB (13.9 MB transferred)

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

Performance › Page Weight Budget
Critical: 4

1 button(s) with no accessible text

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Accessibility › Link & Button Quality
Warning: 5

2 render-blocking <script src> tag(s) without async/defer

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 32.7s 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 32.7s — 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.

  • High main-thread blocking time
    Page is non-interactive for 588ms 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
  • Content is hard to read
    Graduate-level reading difficulty — limits the addressable audience for product or blog pages
    → Shorten sentences; replace jargon with plain language; target Flesch ease ≥60
  • 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

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

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