SEO Audit

Title tags, meta descriptions, heading hierarchy, canonical URLs, robots directives, structured data, and Open Graph tags. The full picture.

🔒

Security Headers

HTTPS, HSTS, Content-Security-Policy, X-Frame-Options, and more. Know if your site is actually protected or just looks like it.

Indie Developers

You built the thing, now make sure it actually ranks. Check your meta tags, security headers, and structured data before launch day. Catch the stuff that's easy to forget when you're building alone.

📈

SEO Professionals

Quick audits for client sites without logging into five different tools. Get a shareable report link or PDF export in seconds. Great for initial assessments and follow-up checks.

🏢

Small Business Owners

You don't need to understand HTTP headers to know your site has a problem. IOn Probe explains each issue in plain English and tells you what to fix first.

🔎

Competitive Research

Scan a competitor's site to see what they're doing right. Check their tech stack, security posture, social presence, and SEO setup. Know where you stand.

Not another
generic checker.

Most site audit tools give you a score and a wall of jargon. IOn Probe gives you the full picture with context.

Social Signal Tracking

We check Reddit, Hacker News, and the Wayback Machine. Most audit tools ignore everything outside of on-page SEO.

Real Security Auditing

SSL certificate details, all six security headers scored individually, mixed content detection, and HTTPS redirect verification.

Tech Stack Detection

See what framework, CMS, CDN, analytics, and payment systems any site is running. Useful for competitive intelligence or just curiosity.

DNS and Domain Intelligence

SPF, DMARC, and DKIM records, WHOIS data, domain age, and nameserver info. Know the full infrastructure picture.

PDF Export and Sharing

Generate a branded PDF report or share a direct link. Perfect for client presentations or team standups.

Zero Friction

No account, no email, no credit card. Paste a URL and get your report. That's it. We built this to be useful, not to harvest leads.
