What is GEO Checker

From the Chrome Web Store

Check GEO / AI indexing readiness. Audit llms.txt, robots AI bots, schema and meta, then copy a ChatGPT knowledge prompt. GEO Checker: AI Indexing & llms.txt Audit Check if any website is ready for Generative Engine Optimization (GEO). Audit llms.txt, robots AI bots, sitemap, schema and meta, then copy a ChatGPT prompt to test what AI already knows about the brand.

🚀 Why Choose GEO Checker? AI assistants and generative search do not see your site the way classic crawlers do. GEO Checker turns your browser into a focused readiness suite so you can score the active tab, spot missing AI signals, and smoke-test brand knowledge in ChatGPT, Claude, or Perplexity in one flow.

📋 What GEO Checker Audits Stop guessing whether AI systems can understand your site. The checklist covers the signals that matter for GEO and AI indexing:

1) AI files: llms.txt and llms-full.txt presence, plus detection when a path is really an HTML SPA soft-404 instead of plain text or markdown. 2) robots.txt AI bots: GPTBot, ChatGPT-User, Google-Extended, ClaudeBot, PerplexityBot, and related AI crawler rules. 3) Discovery basics: sitemap.xml reachability and on-page indexability (noindex). 4) On-page structure: Schema.org JSON-LD, title and meta description, canonical URL, Open Graph. 5) Readiness score: one clear score from the checklist so you know what to fix first.
