Making Your Content Chunkable for RAG

Last updated: June 24, 2026

AI engines don't quote pages, they quote paragraphs. Each paragraph has to stand alone when pulled out of context, or it won't get cited. This article explains chunkability and the rules that make your paragraphs extractable.

What chunking is

RAG (retrieval-augmented generation) systems break pages into chunks, usually by paragraph or heading boundary, embed each chunk as a vector, and retrieve the ones most relevant to a query. The engine then quotes or paraphrases those chunks in its answer. In GEO, "chunks" are essentially paragraphs.

Chunks don't travel with the surrounding page. If your paragraph starts with "As we discussed above, this metric," the engine sees a fragment with no anchor and won't quote it.

The 4 chunkability rules

Rule 1: 50 to 120 words per paragraph. Too short (under 40 words) and the chunk lacks enough context to be meaningful when retrieved. Too long (over 150 words) and it falls below the retrieval-relevance threshold for most RAG systems. Aim for 70–90 words as your default.

Rule 2: One idea per paragraph. Each paragraph answers one question or makes one claim. Test it by writing a one-sentence summary. If your summary contains "and also" or "meanwhile," you have two ideas, so split them.

Rule 3: No mid-paragraph references to "above." Delete phrases like "As mentioned earlier," "As we discussed above," "Continuing from the previous point," and "This ties back to." Replace them with self-contained naming. Instead of "As we discussed above, this metric matters," write "Detection Rate is the primary branded signal. If AI engines can't find your brand on queries that include your brand name, the problem is almost always SEO."

Rule 4: Lead with the claim. Put the main claim in the first sentence; the rest is justification, example, or caveat. This is the BLUF pattern applied at the paragraph level. Instead of "There are several factors to consider when evaluating AI visibility. Among these, one that's often overlooked is...", write "Detection Rate is the single most important metric for diagnosing branded visibility. Below 90% is an entity emergency."

The paste-into-a-blank-doc test

  1. Open your priority page.

  2. Pick one paragraph.

  3. Cut it and paste it into a blank document.

  4. Read it cold.

If you understand what it claims and why without the rest of the page, it passes. If it depends on context, rewrite it. Repeat for every paragraph. Each one has to pass.

The chunk-to-H2 ratio

Aim for one to three body paragraphs under each H2. More than five and you should split the H2 into two. Fewer than one means the H2 is decorative, not functional.

Pick the worst-performing paragraph on your priority page (usually the longest or the one with the most transitional phrases). Cut it, paste it into a blank doc, and read it cold. Rewrite it to pass, and ship today.
