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 24.5 MB (23.9 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.
1 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
¥2,975 investment → ¥32,835/month returns + CNY 50,000,000 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
11 barrier(s) likely increasing bounce by ~33%.
- Page takes 30.4s to loadUsers abandon at ~3s — you're 27.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- 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
- 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
- Layout shifts during page loadContent movement causes mis-clicks on CTAs and form fields→ Add width/height to images; reserve space for late-loading embeds
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.

Top 10% of HSTS sites score 83+ on Security; you're at 59 — closing this gap is the highest-leverage improvement.
Top 10% of jQuery sites score 86+ on Compliance; you're at 61 — closing this gap is the highest-leverage improvement.
Technology stack
HSTS, with Nginx CDN
Stack Architecture
Slick 
jQuery 1.9.1
Nginx All Detected Technologies (4)
Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
jQuery is a JavaScript library which is a free, open-source software designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax.
Observations (2)
No build tool detected
A framework (HSTS) 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.
jQuery version may be outdated
Detected jQuery 1.9.1. The current major version is 3. Consider updating for security patches and new features.
