What This Tool Checks (and What It Doesn't)
This is a complete website checker and website audit tool built by combining five already-existing, dedicated checkers into one report: SEO (title, meta description, canonical, headings, structured data, links), Performance (a real PageSpeed Insights/Lighthouse audit: Core Web Vitals, opportunities, diagnostics), Security (the full Website Security Scanner report: SSL/TLS, HTTP security headers, CORS, DNS/email security, exposed files, outdated libraries, and more), HTTP Headers (caching, compression, validators, CDN fingerprinting), and DNS (basic zone health: address records, nameserver delegation, mail configuration, SOA). It deliberately does not re-implement any of these five tools' logic: each pillar calls that tool's own analysis directly, so what you see here is the same depth, not a lighter summary. It also doesn't do things none of its five pillars do: accessibility auditing beyond what Lighthouse's own accessibility score covers, broken-link crawling, or WHOIS/registrar lookups.
Why Doesn't This Tool Give One Overall Health Score?
A single blended number across five very different areas would invite exactly the wrong comparison: a site that's genuinely excellent at security but average on a notoriously harsh PageSpeed metric would read as "unhealthy" from one number alone, which isn't an honest picture. Instead, SEO's own 0-100 score and Performance's own PageSpeed score are shown exactly as those two tools already report them (real, industry-recognized metrics), while Security, HTTP Headers, and DNS use severity-tagged findings instead of a score, consistent with how Website Security Scanner itself reports (it dropped its own score for the same reason: a well-known site scoring "D" read as broken when the real story was a few specific findings). The "Fix These First" callout answers "what do I actually need to fix" directly, across all five areas at once, rather than through a proxy grade.
Why Does a Full Health Check Take Longer Than a Single Checker?
All five checks run concurrently, not one after another, so the total time is bounded by whichever one is slowest, usually Performance, since a real PageSpeed Insights/Lighthouse audit commonly takes 15-30 seconds and occasionally longer. That's a genuinely more thorough audit running in the background, not five sequential page loads; visiting five separate tools one at a time would take meaningfully longer in total.
