GEO Checker for Generative Engine Optimization
Run a free GEO check in about 20 seconds: see whether AI answer engines can crawl your page, find an llms.txt summary and read your structured data — the technical base of generative engine optimization.
Free: free single-URL checks, up to 10 per hour, no sign-up. This page targets the GEO checker intent; for a broader AI visibility overview see the AI visibility checker homepage.
A GEO checker (generative engine optimization checker) answers a different question from a keyword rank tracker. Generative engines do not show ten blue links; they fetch a few pages and quote them. If OAI-SearchBot or PerplexityBot cannot reach you, or your page has no clear answer and no schema, you will not appear in those answers — no matter how well you rank on Google for the same topic.
GEO Checker focuses on that prerequisite layer: robots.txt rules for nine AI and search bots, a live fetch with each bot’s user-agent (to catch Cloudflare and other WAF blocks), llms.txt detection, and Product / Review / FAQPage / Organization schema with copy-paste JSON-LD. It is free for single-URL checks and needs no sign-up.
What this GEO checker tests
| Area | Why it matters for GEO | Points |
|---|---|---|
| robots.txt for AI bots | OAI-SearchBot, ChatGPT-User and PerplexityBot must be allowed if you want ChatGPT Search and Perplexity citations | 30 |
| Live crawler / WAF access | CDN “Block AI bots” settings can hide you even when robots.txt says Allow | 30 |
| Structured data | FAQPage, Organization and Product markup make passages easier for models to identify and quote | 25 |
| llms.txt | A short Markdown briefing for AI tools and agents (emerging convention) | 10 |
| Title and description | Basic page identity signals | 5 |
How to use the GEO checker in 4 steps
- Paste a key URL — a product, pricing or pillar page, not only the homepage.
- Read the score parts — a low robots or WAF score is usually the first fix; schema and llms.txt come next.
- Apply the suggested fixes — robots.txt groups, Cloudflare allowances, JSON-LD snippets.
- Re-check and deepen — use the AI crawler checker for bot-by-bot detail, the llms.txt checker for the file format, and the ChatGPT citation checker if your goal is ChatGPT Search citations specifically.

FAQ
What is a GEO checker?
A GEO checker (generative engine optimization checker) tests the technical foundations that AI answer engines need: whether AI crawlers can access your pages, whether you publish llms.txt, and whether structured data such as FAQPage, Organization and Product is present. It does not measure keyword rankings the way a classic SEO suite does.
How is GEO different from SEO?
SEO optimizes for traditional search results pages. GEO (generative engine optimization) optimizes so AI answer engines such as ChatGPT Search, Perplexity, Gemini and Copilot can fetch, understand and cite your pages. Overlap is large — crawlability, clear answers, structured data — but the crawlers and citation formats differ.
Is this GEO checker free?
Yes: free single-URL checks, up to 10 per hour, no sign-up.
Does a high GEO score mean ChatGPT will recommend me?
No. A high score means the technical barriers are low. Mentions and citations also depend on content quality, competition and third-party signals. Use this tool first, then track mentions separately.
