About LLM Signal

LLM Signal helps companies understand how AI systems discover and use their website. A snippet under 2 KB, with no cookies, fingerprinting or personal data, identifies visits from AI crawlers such as GPTBot, ChatGPT-User and OAI-SearchBot, and verifies requests against official OpenAI IP ranges so spoofed traffic is separated from legitimate traffic. Dashboards show AI traffic trends by model family, prompt monitoring for high-intent prompts and page-level insights on which pages AI systems revisit.

A GEO Analyst Agent runs the generative engine optimization workflow: it monitors visibility shifts, diagnoses page issues, recommends prioritized fixes and verifies outcomes after deployment. Growth includes a hosted runtime with daily or twice-daily monitoring, an approval queue for actions that change things, run history and weekly summaries, and Pro lets you run a self-hosted agent against the plan and status APIs, compatible with OpenClaw.

LLM Signal is a hosted service with an interactive demo, a free GEO audit and a 7-day free trial. The sample dashboard shows prompt visibility trends, model coverage and the sources and queries that shape AI answers, and the site includes a FAQ and agent documentation.
