What is Factual Density?
Factual Density measures how many verifiable facts your content contains per 100 words. AI engines like ChatGPT, Perplexity, and Google AI Overviews strongly prefer content packed with numbers, percentages, dates, named entities, and research references. Content with high factual density gets cited 62% more often than vague, opinion-based writing.
This metric is part of the Content Quality pillar in your GEO-Score. It counts six categories of verifiable data: numbers, percentages, dates, currencies, measurements, and named entities. The target is 3 or more facts per 100 words.
What Counts as a Fact?
The analyzer detects six categories of verifiable information. Each type signals to AI engines that your content is specific, evidence-based, and worth citing.
Numbers & Percentages
Specific figures like "73% of users", "$4.2 billion", or "reduced by 45%". Percentages are the strongest citation signal.
Dates & Years
Temporal references like "In 2025", "A January 2026 study", or "updated quarterly". Adds freshness and verifiability.
Statistical Language
Phrases like "According to research", "Studies show", "Data indicates". Signals evidence-based writing.
Named Entities
Specific organizations, tools, or people: "Google", "Princeton University", "Semrush". Adds credibility and specificity.
Factual Density Benchmarks
Your score is based on facts per 100 words. Here is how different density levels compare.
Aim for at least 3 verifiable facts per 100 words. This means roughly one specific data point every 2-3 sentences. Content that hits this threshold earns significantly more AI citations.
Why AI Engines Prefer Data-Rich Content
AI engines are designed to provide accurate, trustworthy answers. Content packed with verifiable facts helps them do this confidently.
- Facts can be cross-referenced against the AI's training data for accuracy verification
- Data points give AI engines higher confidence when citing your content as a source
- Specific numbers and entities help AI distinguish your content from generic alternatives
- Dated references and recent statistics signal that content is current and relevant
How to Improve Your Score
Avoid
- ✗"Many people use AI" — replace with "43% of US search users used AI tools in 2025 (Gartner)"
- ✗Making claims without attributing them to a source or study
- ✗"About a million" — be specific: "1.2 million monthly active users"
- ✗Statistics from 3+ years ago without noting the date or updating them
- ✗"AI is clearly the future" — replace with data: "AI search volume grew 527% year-over-year (Previsible 2025)"
Do Instead
- ✓Use specific numbers: "reduced bounce rate by 34%" instead of "significantly reduced bounce rate"
- ✓Reference studies: "According to a 2025 Princeton study" or "Research by Semrush shows"
- ✓Add temporal context: "As of Q1 2026", "In January 2025", "Updated monthly"
- ✓Name specific entities: "Google's BERT algorithm" instead of "search engine algorithms"
- ✓Convert descriptions to data: "most users" → "73% of users (Source, 2025)"
Quick Tips
- •Target 3+ facts per 100 words — one data point every 2-3 sentences
- •Use citation phrases: "According to", "Research shows", "A [year] study by [source] found"
- •Add dates to every claim: "In 2025" or "As of May 2026" for freshness signals
- •Reference specific organizations by name — AI engines verify against their knowledge base
- •Include precise measurements: "4,700ms load time", "134-167 words", "62% improvement"
- •Update statistics annually — AI engines deprioritize content with outdated data
Before & After Example
AI search is becoming more popular. Many people now use AI tools instead of traditional search engines. This is changing how content should be written. Companies need to adapt their strategy to stay visible. The trend is expected to continue growing in the coming years.
AI-powered search grew 527% year-over-year in 2025 (Previsible AI Traffic Report). Gartner predicts traditional search volume will drop 25% by 2026 as 31.3% of US users adopt generative AI search tools (EMARKETER, 2026). According to SE Ranking's November 2025 study of 129,000 domains, pages with 3+ verifiable facts per 100 words earned 62% more AI citations than low-density content. Organizations like Google, Microsoft, and Perplexity now prioritize data-rich, recently updated content in their AI answer generation.
