About Website Auditor
A full-fledged website auditor — not just a security scanner.
Website Auditor runs the same checks you'd otherwise stitch together from SecurityHeaders, Mozilla Observatory, SSL Labs, PageSpeed Insights and a dozen SEO tools — in one shareable report, with a transparent 0–100 score.
What Website Auditor does differently
One report, six categories
Instead of grading only headers or only SEO, Website Auditor rolls every probe into a weighted category score so you can see where to invest next.
Actionable, copy-paste fixes
Each failing check ships with concrete remediation and a ready-made AI fix prompt scoped to your exact host and stack.
Runs at the edge
Deployed on Cloudflare Workers with parallel probes — a full audit completes in seconds, not minutes.
Free public API & badge
Any report is available as JSON at /api/public/audit/<domain>and as an SVG badge at /badge/<domain>.svg.
The six audit categories
Every check contributes to exactly one category so the score stays explainable.
Security
25%HTTPS, TLS/cert chain, HSTS, CSP, cookie flags, reputation, redirects and information disclosure.
Infrastructure
15%DNS, DNSSEC, CDN, WAF fingerprinting, HTTP/2 & HTTP/3 support, compression and stack detection.
SEO & Content
20%Meta, canonical & robots directives, sitemap health, JSON-LD structured data, accessibility heuristics and broken links.
Email Security
10%SPF, DKIM selector hints, DMARC policy, MTA-STS and TLS-RPT for the sending domain.
Performance
15%PageSpeed (Lighthouse) with actionable opportunities, real fetch timings, resource weight and carbon footprint.
Trust & Transparency
15%WHOIS age, privacy policy discovery, tracker inventory and third-party disclosure signals.
The Website Auditor Score
Every probe returns a 0–100 sub-score weighted by severity (critical, high, medium, low, info). Sub-scores roll up into their category, and categories roll up into the final grade using these weights:
- Security — 25%
- SEO & Content — 20%
- Infrastructure — 15%
- Performance — 15%
- Trust & Transparency — 15%
- Email Security — 10%
Grade bands: A+ ≥ 95 · A ≥ 85 · B ≥ 75 · C ≥ 60 · D ≥ 45 · F below 45.
