Retrieval-Augmented Generation
Retrieval-Augmented Generation (RAG)
An architecture where a language model retrieves relevant external documents at query time and grounds its answer in them, rather than relying only on training data. Understanding RAG explains why fresh, well-structured, authoritative pages earn AI citations: they are the documents being retrieved.
How Retrieval-Augmented Generation works in practice
Retrieval-augmented generation is the architecture behind most cited AI answers: rather than relying solely on frozen training data, the system retrieves relevant documents at query time and grounds its response in them, then attributes the sources. Understanding RAG demystifies generative engine optimisation — if the model is retrieving and synthesising documents, then being retrieved is the objective, and that favours pages that are fresh, well-structured, semantically clear, and authoritative on a tightly scoped question. It also explains why thin, derivative content is invisible to AI search even when it ranks adequately in classic results: it offers no information gain over what the model already has, so it is neither retrieved nor cited. Optimising for RAG means writing the document you would want the model to quote.
