/ FEATURES
139 checks across 8 categories — plus 28 schema types and 15 AI crawlers. Every check is backed by a real source — Google's own documentation, not our opinion — and re-checked every 90 days so the advice never goes stale. Most tools won't tell you why they flag something. We show you, every time.
/ WHAT IT DOES
Find blocked AI crawlers | We test your robots.txt against 15 named AI crawlers. Most sites accidentally block the ones they most want reading them. |
Validate (or generate) your llms.txt | The emerging standard that tells AI assistants what is citable. We flag what is missing — and generate a ready-to-ship file if you do not have one. |
Catch deprecated schema | Some schema types have lost rich-result eligibility or are sector-restricted. We flag the ones that no longer earn results — most validators only check that the JSON parses. |
Validate the schema graph | We validate the JSON-LD entity graph, not just individual fields — catching structural defects a field-by-field validator never sees. |
Measure real Core Web Vitals | Real-user Core Web Vitals — the numbers Google actually ranks on — not just lab estimates. |
Benchmark against your sector | Your score against the median and top quartile of real sites in your sector — not a number in a vacuum. |
Audit a whole site, not one page | Deep Audit samples across your whole site and flags "fix once, lift every page" template bugs. |
Run a real accessibility audit | A real WCAG accessibility audit — critical, serious and moderate issues — on every rendered scan. |
Check security + TLS | TLS, security headers, mixed content and stack disclosure — the hygiene AI crawlers and users both notice. |
Detect agent-auth readiness | We check /.well-known/agent-auth — the emerging standard for authenticating AI agents that act on your behalf. Adoption is early; declaring it puts you ahead of 99% of the web. |
Get a priority-grouped fix roadmap | Every issue is bucketed by priority — today / this week / this quarter — with copy-paste fix code. You see exactly what to do first. |
See the working, not just the score | Every weight carries a cited source, labelled by strength of evidence and re-reviewed every 90 days. Answer "why does this matter?" in seconds. |
Twelve headlines, 139 individual checks. Each category below shows its size and severity mix — the per-check findings and fixes run in your report.
/ SCHEMA MARKUP
29 types audited with sector-aware deprecation rules — some retired, some restricted to certain sectors, some time-boxed. We validate nested required fields, not just presence.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ HEAD + META SIGNALS
The 15+ HEAD-level signals Google ranks on and AI assistants read first.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ AI CRAWLER ACCESS + LLMS.TXT
robots.txt access for 15 named AI crawlers (GPTBot, ClaudeBot, PerplexityBot, etc.), llms.txt validity, llms-full.txt detection, and crawler-blocking severity tiered by 'live citation' vs 'training only'.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ CONTENT STRUCTURE + E-E-A-T
Main-content extraction via Mozilla Readability so we don't count nav chrome. Heading hierarchy, H1 quality, alt-text, reading level, internal links, semantic HTML5, author + date for E-E-A-T.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ PERFORMANCE + CORE WEB VITALS
CrUX field data via PageSpeed Insights (the metric Google actually ranks on). Synthetic checks for render-blocking, third-party scripts, preconnect hints. Lighthouse category scores.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ SECURITY + INFRASTRUCTURE
TLS cert expiry + protocol version, security response headers, mixed http:// content, caching strategy, theme-color, PWA manifest, hreflang return-link symmetry.
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ URL HYGIENE + ERRORS
Soft-404 probes, canonical round-trip validation, redirect chains, pagination markup, AMP awareness, tracking-param canonicals, mailto/tel hygiene, accessibility (skip links).
Severity mix
Each check's finding + copy-paste fix runs in your report.
/ SCHEMA TYPES
Beyond presence detection, each type has nested required-field validation and sector-aware deprecation rules — we track which still earn rich results. Most validators only check that the JSON parses. Per-type status (active / deprecated / restricted) is in your report.

We test each User-Agent against your robots.txt using a longest-match-wins parser that handles wildcards, Allow rules, and per-group Crawl-delay. We tier them by whether they fetch live for citations or only for training, and weight a block accordingly — which bot sits in which tier is in your report.

Same scanner under every tier. The differences are scope (one page vs whole site) and cadence (one-time vs ongoing). Studio adds programmatic access.

/ METHODOLOGY
Know whether AI search cites your brand — and fix it when it doesn't. Every weight cited and re-reviewed every 90 days. Every artefact below is a real file path in our open repo — click through, read it, fork it.
Every signal weight carries a source URL and EVIDENCE / HEURISTIC / CORPUS-CALIBRATED rationale. When a client asks "why is this -8?" you can answer in seconds. Nobody else shows their work.
A growing corpus of 50+ labelled real sites tells us which rules actually predict citation outcomes. Weights tune to the data over time — run `npm run corpus:stats` to reproduce the per-rule correlations.
Every rule has a lastReviewed date. `npm run audit:stale` fails CI when anything crosses 90 days unverified. Google quietly deprecates schemas; bot operators rename UAs — without an audit cycle, your tool rots. Ours can't.
