Semantic Chunking
In one line
Semantic Chunking splits content along meaning boundaries rather than fixed lengths — preserving context inside each passage and producing GEO-friendly citation units.
Going deeper
Semantic Chunking splits text along meaning boundaries rather than fixed lengths like 'every 500 tokens'. Each chunk closes around a coherent unit — one topic, one definition, one step — which preserves context when an LLM lifts the passage into an answer.
On the content side, the leverage is structural: the page has to be written so that meaning-aware splitting is even possible. An H2 section that quietly mixes several topics, or a paragraph that wraps up two conclusions at once, makes clean semantic chunks hard and pulls citation odds down.
Practical move — apply 'one section, one answerable question' a little more strictly. Lead the section with the answer sentence, follow with evidence and examples, and close the section before pivoting topics. Meaning-aligned chunks fall out of that structure almost for free.
