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

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
Critical: 3

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: 4

Page weighs 9.4 MB (4.8 MB transferred)

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

Performance › Page Weight Budget
Critical: 5

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
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 24.5s 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.
3 security gaps detected — browsers may warn visitors about your site.
Your LCP is 24.5s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.
1 accessibility issue excludes users who rely on assistive technology.

Business case

What fixing the audit's findings is worth -- and what ignoring them keeps costing.

  • Page takes 24.5s to load
    Users abandon at ~3s — you're 22.0s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 1.2s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 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
  • 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 (Django) 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

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