Chunks: does every part stand on its own? Chunking
AI search does not read a whole page in one go. It splits the text into chunks of 100 to 300 words and cites single ones. Every chunk must be understandable without the rest.
Experimental. The tools are based on public statements by AI providers, current studies, published assessments by AI and SEO experts and hands-on experience of site owners. AI platforms do not disclose their criteria, so the results are approximations, experience and observations.
1What is it?
TagSpion splits the main content at headings or by word count into chunks and checks each one: does it have a topic, a heading, a sensible length? Does it refer to "above" or "as mentioned"?
2Why it matters
If a chunk starting with "As mentioned above" is cited, nobody understands it. Chunks that name their topic themselves are cited more often and correctly.
3What TagSpion checks
| Check | Rating |
|---|---|
| Length | green 40 to 200 words · yellow shorter or longer |
| Heading present | yellow if the chunk starts without a heading |
| External references ("above", "as mentioned", "see below") | yellow, not self-contained |
4How to fix it
- Every chunk names its topic in the first sentence, ideally with the term from the heading.
- Instead of "as described above", repeat the core in one sentence.
- Split long chunks with subheadings.

Which chunk size is right?
Nobody knows the providers' values. 100 to 300 words is the range most often mentioned in studies and practice. The slider in the tool shows how robust your text is.
