Retrieval-Augmented Generation (RAG)
A technique AI systems use to improve accuracy by retrieving relevant, up-to-date content from external sources — websites, documents, databases — before generating a response, rather than relying only on what the model memorised during training. RAG is why fresh, well-structured content increases citation chances.
Why it matters
It's the mechanism behind most AI Overviews and chat-with-search features — content the retrieval step can actually find and parse is the content that gets cited.
