Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
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 14.4 MB (4.9 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
19 link(s) with no accessible text
Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.
2 image(s) missing alt attribute
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
£600 investment → £3,503/month returns + GBP 18,050,000 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
8 barrier(s) likely increasing bounce by ~33%.
- Page takes 15.6s to loadUsers abandon at ~3s — you're 13.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 5.1sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- Severe layout shift during page loadUsers mis-click when content jumps — converting intent into frustration→ Reserve space for images, ads, and embeds with explicit width/height
- 11 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
- 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.
