Free GEO Tools

No-signup utilities that operationalize the playbooks this wiki documents. Each tool states what it measures, quotes its evidence, and says plainly what it cannot see.

• Citability Checker

  Per-signal verdicts on how liftable a page is for AI answers, with the failing passage quoted as evidence. No 0–100 score, on principle.

• Schema Markup Checker

  Four-rung verdicts on a page's JSON-LD — delivery, validity, graph integrity, truth — finding the @id collisions and dead sameAs targets every validator shows as green.

• AI Crawler Access Checker

  robots.txt verdicts for 26 AI crawler tokens — quoting the exact rule line — plus differential edge probes that surface UA-keyed CDN and WAF rules.

• llms.txt Generator

  Crawls your sitemap and page metadata, then drafts a curated llms.txt to spec v2. Links come only from the crawl, never invented.

House rules all four share

• Free and anonymous, with a daily quota; signing in raises it. No account is ever required.
• Every verdict carries its evidence — the rule line, the passage, the crawl data it came from.
• No black-box numbers. Where a measurement cannot be made honestly, the tool says so instead of guessing.
