Introduction
Before content can be surfaced in an AI-generated response or a Generative Engine Optimization (GEO) result, the underlying AI bot must be able to crawl and ingest the data. While most SEO practitioners are familiar with Googlebot, the ecosystem for AI visibility involves a distinct set of crawlers with different behaviors, IP ranges, and retry cadences. If your robots.txt or server-side firewall (WAF) is inadvertently blocking these agents, your visibility efforts are void. This lesson provides a technical framework for verifying that AI bots can reach your content using server logs and live probes.
