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
Warning: 4

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

Performance issues directly impact user engagement and conversion rates.

Performance › JavaScript Blocking
Warning: 5

15 third-party resources (93% 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 is in great shape. The remaining improvements are refinements rather than critical fixes. Your page blocks user input for 212ms — visitors may think the site is frozen. 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.
2 performance issues — Akamai's research found 53% of mobile users abandon pages over 3s.

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.

  • High main-thread blocking time
    Page is non-interactive for 212ms after first paint
    → Defer third-party scripts and split large bundles
  • 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
  • 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
  • 1 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 (Astro) 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

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