Content Chunking
Splitting a page into smaller self-contained passages that retrieval systems embed and match against queries, the unit an AI actually retrieves and cites.

Content chunking is how retrieval pipelines break a document into passages before embedding them as vectors. When a user asks a question, the system matches the query against individual chunks, not entire pages, so the chunk, not the page, is the unit of citation.
Why does chunking affect AI citation?
If your key claim is split awkwardly across a chunk boundary, or buried in a chunk that also covers three other topics, it embeds poorly and is less likely to be retrieved. Tight, single-idea sections that stand on their own embed cleanly and surface as citations.
How do I structure content for clean chunking?
Use descriptive H2/H3 headings, keep each section focused on one question, front-load the answer, and avoid pronouns that depend on distant context. A section that reads correctly in isolation chunks well and retrieves well.
Is chunking the same as RAG?
Chunking is one step inside retrieval-augmented generation (RAG). RAG is the end-to-end pattern of retrieving relevant passages and feeding them to a model; chunking is the upstream preparation that decides what those retrievable passages are.
