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

114 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: 5

115 HTTP requests — consider bundling or reducing

High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

Performance › Page Weight Budget
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 3.7s 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.
3 security gaps detected — browsers may warn visitors about your site.
Your LCP is 3.7s — fixing the 2 performance criticals could bring it under Google's 2.5s 'Good' threshold.

Business case

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

  • Page feels frozen for 3.3s
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • Page loads in 3.7s
    Every additional 100ms above 2.5s costs conversions — you're 1.2s over
    → Target <2.5s LCP: defer non-critical scripts and optimize the hero image
  • 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
  • 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, …)

Observations (3)

Server version exposed in headers

The Server header reveals 'IIS 10.0'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.

→ Security

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

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