Information Density: How Much Useful Information Your Content Packs

Why information density determines whether AI quotes your content or skips it.

What it measures

Information Density measures the ratio of meaningful content (named entities, facts, numbers, specific claims) to total word count. It's the category score combining Entity-to-Token Ratio and Fluff/Bloat Penalty.

Why it matters for AI

AI systems prefer content that is packed with concrete, citable information rather than vague generalities. Pages with higher density are more likely to be quoted in AI-generated answers because they provide specific data points AI can reference confidently.

How to improve

Replace filler phrases with concrete facts — Every sentence should earn its place
Add statistics with sources — Numbers are the currency of AI citations
Name specific people, companies, and products — Generic references get skipped
Include dates and numbers wherever relevant — Temporal anchoring adds density

💡 Quick win

For every claim you make, ask: "Could AI quote this sentence with confidence?" If not, add specifics.
