Quick Answer (TL;DR): Information density measures how many factual claims, data points, and source citations exist per word of content. Higher density pages are preferred by LLMs since they provide more extractable signal per token. Target 0.015 to 0.025 citations per word and 1 to 2 data...

Calculating Information Density

Information density is the ratio of factual claims to total words. A claim is a statement that can be verified or falsified with external data. For example, "Google processed 3.5 billion searches per day in 2025" is one claim. "Google is a search engine" contains no specific density (it is common knowledge). Target 0.015 to 0.025 claims per word. A 600 word post should contain 9 to 15 verifiable claims. Each claim should include a source, a data point, and a year where applicable (Moz, "Token Efficiency in Content for LLMs," February 2026).

Eliminating Low Density Passages

Every paragraph should earn its place. Remove filler sentences that add context without new information. Instead of "Page speed is an important factor that many SEO professionals consider when optimizing websites," write "Page speed directly affects conversion rates. A 2026 Portent study found a 2.5x difference between 1 second and 5 second load times." The second version contains 3 claims in fewer words. Low density passages are the first content LLMs drop during passage extraction.

Entity Rich Writing

Named entities (people, companies, products, technologies) increase information density. Each entity anchors a claim to the real world. "Google's AI Overviews, launched in May 2024, appear for 64% of queries" contains three entities and one data point in 12 words. Compare with "The new search feature from the big tech company shows up for many searches" which contains zero extractable entities. Entity rich writing gives LLMs more hooks for knowledge graph integration (Perplexity, "Entity Density Benchmarks for Web Content," 2025).

Balanced Density for Readability

Maximum density does not mean minimum readability. Paragraphs with 3+ claims per sentence become unreadable. Maintain a rhythm of 1 to 2 claims per sentence and 2 to 4 sentences per paragraph. The most effective posts combine high fact density with natural flow. A 2025 readability study by Search Engine Land found that pages scoring well on both Flesch Reading Ease (under 60) and claim density (over 0.015 per word) appeared in AI Overviews at the highest rate (Search Engine Land, "Readability vs. Density in AI Search," November 2025).

Citation Density as a Trust Signal

Pages with consistent citation density signal thoroughness. If you make 5 claims and cite 5 sources, your citation density is 100%. If you make 10 claims and cite only 2 sources, the ratio drops to 20%. LLMs may deprioritize content with low citation ratios. Aim for 70% or higher citation coverage across your factual claims.

Frequently Asked Questions

Q: What is the minimum information density for AI Overview inclusion? A: Industry benchmarks suggest 0.012 claims per word minimum. Posts below this threshold rarely appear in AI Overview extracts.

Q: Does high information density hurt human engagement? A: Not when balanced with readability. High density content with clear structure keeps readers engaged since every sentence delivers value.

Q: How do I measure my content's information density? A: Count verifiable claims and divide by total word count. Track this as a quality metric in your editorial process.

Q: Does density affect EEAT? A: Yes. High density with proper attribution signals Expertise. Low density with vague claims signals low authority.
