Generative discovery evidence
GEO Inspector
Check whether a public page is technically accessible to major AI crawlers and exposes useful machine-readable context. Evidence only — no opaque score and no promise of citation.
What this does — and does not — tell you
OAI-SearchBot and PerplexityBot are search-oriented crawler signals. GPTBot is an OpenAI training control. Google-Extended is a Gemini training/grounding product token and does not control Google Search ranking. llms.txt is an emerging convention, not a universal requirement.
GEO Inspector does not query ChatGPT, Gemini, or Perplexity to see whether your brand is actually mentioned. That observed-visibility problem belongs to AIO measurement.
