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 14.6 MB (6.5 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
10 control(s) without accessible label
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
34 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
£563 investment → £4,722/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 ~28%.
- Page feels frozen for 1.3sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 10 form field(s) without a labelScreen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes→ Associate every input with a visible <label for="…">; add autocomplete attributes
- 4 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

Observations (3)
WordPress detected — review security configuration
WordPress sites benefit from: protecting wp-login.php, disabling XML-RPC if unused, restricting REST API access, and keeping all plugins and themes up to date. Check the Security tab for specific findings.
No build tool detected
A framework (Google Font API) 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
19 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
