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 11.9 MB (6.8 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

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
10 barrier(s) likely increasing bounce by ~40%.
- Page takes 23.4s to loadUsers abandon at ~3s — you're 20.9s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 783msClicks 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
- No viewport meta tagMobile browsers render at desktop width and shrink — text unreadable, tap targets miniature→ Add <meta name="viewport" content="width=device-width, initial-scale=1">
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains

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.

How you compare
Where this site stands against peers running the same stack.
Top 10% of Google Search Console sites score 85+ on Compliance; you're at 66 — closing this gap is the highest-leverage improvement.
Top 10% of Microsoft sites score 85+ on Compliance; you're at 66 — closing this gap is the highest-leverage improvement.
Technology stack
Google Search Console, on IIS/ASP.NET, hosted on Microsoft IIS
Stack Architecture
Microsoft ASP.NET 
Windows Server ASP.NET 
IIS 10.0 Microsoft IIS 10.0All Detected Technologies (8)
Internet Information Services (IIS) is an extensible web server software created by Microsoft for use with the Windows NT family.
ASP.NET is an open-source, server-side web-application framework designed for web development to produce dynamic web pages.
Windows Server is a brand name for a group of server operating systems.
Observations (3)
Server version exposed in headers
The Server header reveals 'IIS 10.0'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.
No build tool detected
A framework (Google Search Console) 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
8 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
