## What is a website health scan?

A website health scan is a single automated audit of an entire domain that checks it for
security vulnerabilities, search & AI-engine visibility gaps, and accessibility (WCAG)
issues at once — and returns prioritized, exact fixes. VitalSite runs all of them in one pass
so you don't need separate tools.

## What VitalSite checks (15 security + 16 accessibility checks, plus an AI-visibility audit)

- Security (15 checks): SSL/TLS, security headers, HTTPS enforcement, cookie security,
  mixed content, sensitive file exposure, directory listing, DNS records (SPF/DMARC/DKIM/CAA),
  Subresource Integrity, tech-stack fingerprinting, CVE matching (NVD), malware/blacklist
  (Google Safe Browsing + VirusTotal), open-redirect, error-page leakage, robots/sitemap,
  and (Agency) authenticated passive panel scanning.
- SEO & AI Visibility (GEO/AEO): how discoverable a site is to Google and AI engines (ChatGPT,
  Claude, Perplexity) across six categories — LLM optimization, structured data, AI
  crawlability, authority, content clarity, and technical SEO. Powered by GeoPageScan.
- Accessibility (WCAG 2.1): 16 categories via axe-core — contrast, alt text, labels, ARIA,
  keyboard navigation — the same standard referenced in ADA lawsuits.

## How it works

- Crawls the ENTIRE domain (every page), not just one URL.
- Produces an AI fix guide per finding: plain-English explanation, attack/impact scenario,
  exact copy-paste fix (stack-aware for WordPress/Nginx/Apache/Cloudflare/Vercel),
  estimated fix time, and a verification step.
- Never exploits or attacks systems. Deep Scan (Agency) does authenticated PASSIVE checks
  of your own admin panel with credentials you provide (never persisted).
- Scores each pillar 0–100. Bands: 90–100 Excellent, 70–89 Fair, 40–69 Poor, <40 Critical.
