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

Three pillars. One scan.
Most teams pay for three separate tools. VitalSite checks security, visibility, and accessibility together — and writes the fixes.
Security
17 deep checks per page — SSL/TLS, headers, exposed files, DNS, malware reputation, CVE matching and more, scored 0–100 with exact fixes.
Visibility Intel
GEO/AEO/SEO audit — how discoverable you are to Google and AI engines (ChatGPT, Claude, Perplexity), across 6 scored categories.
Accessibility
16 WCAG 2.1 checks via axe-core — contrast, alt text, labels, ARIA, keyboard nav — the same standard referenced in ADA lawsuits.
17 security checks, every page
Plus 16 WCAG 2.1 accessibility checks and a full GEO/AEO/SEO visibility audit — 33 checks in total. Click any security check to learn what it catches and exactly how to fix it.
