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.
🔥 Top Professional Features
Live Active-Tab Scan: Open any https site, click the icon, and get a fresh GEO checklist without leaving the page.
SPA Fallback Detection: Catch fake 200 homepage HTML on /llms.txt, /robots.txt, and similar paths that break AI scanners.
AI Knowledge Prompt Packs: One-click copy prompts for ChatGPT, Claude, and Perplexity with the domain, score, and gaps filled in.
Rescan in One Click: Fix a file or meta tag, rescan the same tab, and confirm the score moved.
Free Core Forever: Full checklist and prompt packs stay free. Optional "tools we recommend" links stay disclosed if enabled.
🛠 Built for Founders, SEOs & Agencies
Whether you ship a product site, run technical SEO, or audit client domains for AI visibility, GEO Checker is a fast visual alternative to hand-checking robots, llms.txt, and schema in DevTools. It is a practical companion for modern Firefox workflows, not a slow full-site crawler.
Install GEO Checker and make sure generative engines can actually understand your site.
