What is Factual Density?
Factual Density measures how many verifiable facts your content contains per 100 words. Think of it as a simple count: every number, percentage, date, named organization, and research reference in your text adds to the total. AI engines like ChatGPT, Perplexity, and Google AI Overviews strongly prefer content packed with these data points. A 2026 Presence AI study found that content with 5 or more facts per 100 words achieves a 71% citation rate — compared to just 34% for content with 0-1 facts per 100 words.
This metric is part of the Content Quality pillar in your GEO-Score. The analyzer counts six categories of verifiable data: numbers, percentages, dates, currencies, measurements, and named entities. The target is 3 or more facts per 100 words — roughly one specific data point every 2-3 sentences.
Why This Matters for AI Search
intro
AI engines do not read your content like a human browsing a blog post. They scan it for extractable, verifiable information they can confidently include in their answers. Content without facts gives them nothing to work with.
