Indexing
Indexing is a foundational concept in Generative Engine Optimization and AI retrieval — the discipline of making content findable, retrievable, and citeable by large language models.
What is Indexing?
Indexing is a core building block of Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO). It describes one of the mechanisms by which large language models retrieve, rank, or attribute content when generating answers. Understanding Indexing is required to design content, sources, and structured data that AI systems can reliably surface.
Why it matters for AI search
AI search rewrites the rules of discoverability. Indexing matters because it sits inside the pipeline that decides which content gets retrieved, which sources get cited, and which brands get recommended. Teams that optimise for Indexing compound their authority across every AI assistant their buyers use.
How Findable approaches this concept
Findable treats Indexing as a signal to monitor, not a tactic to chase. The platform tracks how Indexing interacts with the Sources, Authority, and Prompt modules so teams can see — with real prompt-level evidence — whether their GEO investments are translating into AI citations and recommendations.
Example
An AI assistant building an answer about "best project management tools" will pull passages from multiple sources, score them for relevance, and cite a subset. Indexing is one of the mechanisms that decides which of your pages make it into that final answer.
