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 5.7 MB (5.6 MB transferred)

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

Performance › Page Weight Budget
Warning: 4

84 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

Cookie 'TS01c28963' has no SameSite attribute

Without SameSite, cookies ride along on cross-site requests — enabling CSRF attacks that SameSite=Lax blocks for free.

Security › Cookie Security
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 34.1s 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 34.1s — 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 takes 34.1s to load

    → 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
  • 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 Open Graph tags
    Links shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop
    → Add og:title, og:description, og:image, og:url to the page head
