Context Window
Context Window 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 Context Window?
Context Window 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 Context Window 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. Context Window 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 Context Window compound their authority across every AI assistant their buyers use.
How Findable approaches this concept
Findable treats Context Window as a signal to monitor, not a tactic to chase. The platform tracks how Context Window 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. Context Window is one of the mechanisms that decides which of your pages make it into that final answer.
