A full website health check in a few minutes
A website can look fine in your own browser and still have problems that cost visitors and rankings: an SSL certificate that expires next week, a redirect chain that adds a second to every page view, missing security headers, a robots.txt that blocks AI crawlers, or a title tag that search engines truncate. These tools check those things from the outside, the same way search engines and browsers see your site.
Suggested order for an audit
- Is It Down? and the Redirect Checker: confirm the site answers and that
http://,wwwand non-wwwversions end on one canonical HTTPS URL in a single hop. - SSL Certificate Checker and HTTP Headers Checker: certificate validity, chain and expiry, then HSTS, CSP and other security headers.
- Website Security Scanner: a passive, graded report you can print or share.
- Website Speed Test: server response time, page weight and the biggest speed wins.
- SEO Checker and AI Search (GEO) Checker: on-page SEO, structured data, and whether ChatGPT, Perplexity and Google's AI features can read and cite the page.
- WHOIS Lookup and Website Location & Hosting Checker: who registered the domain, when it expires, and where the site is hosted.
For your own safety, the Phishing Email Analyzer checks a suspicious message for spoofed senders and dangerous links, the Blacklist Checker shows whether your IP is listed by spam blocklists, and the WebRTC Leak Test confirms your VPN is not leaking your real address.
All scans are passive: they request public pages the way a browser does and never attempt to break in. Network diagnostics such as ping, DNS and port checks are in our network tools.
