From problem to fix in minutes.
Scan
Crawl your entire website and identify every issue across security, SEO, AI visibility and accessibility.
Understand
See exactly what is wrong, why it matters, and how severe each issue is — in plain English.
Fix with AI
Copy a complete, stack-aware fix prompt into Claude Code, Cursor, ChatGPT or your preferred AI developer.
Verify
Run the scan again and see whether the issues were actually fixed — and watch your score climb.
One report. Every problem, ranked and fixable.
Missing Content-Security-Policy header
Without a CSP, a single injected script can run in your visitors' browsers — the root of most cross-site scripting (XSS) attacks.
Add a Content-Security-Policy response header, starting in report-only mode, then enforce it once nothing legitimate is blocked.
Copy the complete fix prompt into your AI coding assistant.
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 plus a copy-paste prompt for your AI coding assistant. VitalSite runs all four in one pass, so you don't need separate tools.
Four pillars. One scan.
Most teams pay for three or four separate tools. VitalSite checks security, SEO, AI visibility and accessibility together — and writes the fixes.
Security
Protect your website from common security weaknesses — headers, SSL/TLS, exposed files, DNS, malware reputation and known CVEs.
SEO
Find technical SEO problems affecting how search engines crawl and index your site.
AI Visibility
See how prepared your site is for Google and AI search engines like ChatGPT, Claude and Perplexity — GEO / AEO readiness.
Accessibility
Identify WCAG 2.1 accessibility issues that affect real users — contrast, alt text, labels, ARIA and keyboard navigation.
Don't just find the problem. Fix it.
VitalSite turns audit findings into practical, stack-aware instructions — including a complete prompt you can paste into your AI coding assistant.
Fix your website, then prove it worked.
Fix your website, rescan it, and verify the improvement.

Plus 16 WCAG 2.1 accessibility checks and an AI-visibility (GEO/AEO/SEO) audit. Click any check to learn what it catches and exactly how to fix it.
