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.
Page weighs 14.3 MB (13.6 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
3 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€608 investment → €6,539/month returns + EUR 500,000 risk avoided
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
7 barrier(s) likely increasing bounce by ~22%.
- 33 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- Page loads in 3.7sEvery 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 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 structured dataNo 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, …)
