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 17.6 MB (16.3 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
1 control(s) without accessible label
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
HKD 3,988 investment → HKD 56,537/month returns
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
11 barrier(s) likely increasing bounce by ~38%.
- Page takes 18.5s to loadUsers abandon at ~3s — you're 16.0s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Mixed content on HTTPS pageBrowsers block insecure subresources — broken images, missing scripts, warning badge→ Change http:// URLs inside the page to https:// (or protocol-relative)
- 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
- 10 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
- High main-thread blocking timePage is non-interactive for 335ms after first paint→ Defer third-party scripts and split large bundles
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

How this is calculated
Based on Google/Deloitte research ("Milliseconds Make Millions") showing a ~7% bounce rate increase per additional second of LCP above the 2.5s "Good" threshold.
Your site's LCP: → estimated after fixes.
