Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
Cookie 'sl-session' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
Soft 404: server returns HTTP 200 for non-existent pages
Soft 404s (HTTP 200 for missing pages) confuse Google — it indexes the 'not found' page as real content and ranks it.
1 publicly-accessible JavaScript source map(s)
Source maps reveal original source code (variable names, comments, file structure) and are shipped to production by mistake almost universally. The standard fix is a one-line build-tool config change.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.

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
5 barrier(s) likely increasing bounce by ~18%.
- Page loads in 3.6sEvery additional 100ms above 2.5s costs conversions — you're 1.1s over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- 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
- Thin contentUnder 300 words — visitors bounce looking for substance, search engines rank competitors first→ Add a substantive FAQ, product detail, or case-study section
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Open Graph 
React 18.3.1All Detected Technologies (5)
HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web.
Open Graph is a protocol that is used to integrate any web page into the social graph.
React is an open-source JavaScript library for building user interfaces or UI components.
Observations (1)
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.
