How RAG actually behaves in education & edtech
RAG is the mechanism through which LLM citations of fresh content happen. The LLM searches an external index (often Bing or its own crawler index), retrieves top-N documents, and generates an answer conditioned on those documents. For brands, this means: (1) Be in the LLM's index. (2) Have schema-rich pages. (3) Have authoritative content. (4) Use llms.txt to surface canonical pages. Pages optimized for RAG are usually also good for traditional SEO.
