Information Density

Information Density measures the ratio of valuable, citable information to total text volume — a metric that influences how AI systems evaluate content quality.

In the CQS (Content Quality Score) formula it carries a weight of 0.15. Implementation involves substituting vague qualifiers with quantified data. Replace 'heart rate increases noticeably' with 'heart rate increases by 20–40 beats per minute'. Content with specific facts and numbers receives higher citation rates from AI Search systems.

Information density connects directly to Cost of Retrieval (the computational effort required to extract information) — the more facts per sentence, the lower the cost of information extraction for AI systems.
