LLM Indexing
The process by which content is ingested and made available to large language models and agentic systems.
Definition
LLM indexing is the process through which web content is crawled, processed, and stored for use by LLMs and AI agents. It includes traditional search indexing as well as agent-specific mechanisms (e.g. llms.txt, structured data) that influence how your site is represented in agent knowledge.
Relevance to GEO
Ensuring your content is indexable in a clear, structured way improves how agents retrieve and cite your pages. GEO practices directly support better LLM indexing outcomes.
