Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
35 third-party resources (86% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

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.
Conversion barriers
8 barrier(s) likely increasing bounce by ~35%.
- Page takes 8.5s to loadUsers abandon at ~3s — you're 6.0s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- No viewport meta tagMobile browsers render at desktop width and shrink — text unreadable, tap targets miniature→ Add <meta name="viewport" content="width=device-width, initial-scale=1">
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher 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 tagsLinks shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop→ Add og:title, og:description, og:image, og:url to the page head
