# Write Like an AI Magnet: The Fact Density Formula

Research from the Princeton NLP lab is unambiguous: pages with at least 12 concrete facts per 500 words are 3.4× more likely to be cited by AI systems. But most content reads like marketing copy — vague, qualitative, and impossible for an AI to extract anything useful from.

## What Counts as a "Fact"?

In the context of AI extraction, a fact is any statement that is:

- Verifiable — Can be confirmed or denied with evidence
- Specific — Contains named entities, numbers, or dates
- Discrete — Stands alone without needing surrounding context

Examples of extractable facts:

- "PostgreSQL 16 supports HNSW vector indexes via the pgvector extension" ✅
- "The CAX11 ARM instance costs €3.79/month and provides 2 vCPU, 4GB RAM" ✅
- "Cloudflare reported an 80% token reduction when serving Markdown vs. HTML (Feb 2026)" ✅
- "WordPress powers 43% of all websites according to W3Techs" ✅

Examples that are NOT extractable facts:

- "Our solution is industry-leading" ❌ (unverifiable)
- "Many companies have seen great results" ❌ (vague)
- "The market is growing rapidly" ❌ (no numbers)
- "We're passionate about quality" ❌ (opinion)

## The Rewrite Method

Take any paragraph from your site and apply this three-step rewrite:

### Step 1: Identify Vague Claims

> "Our platform significantly improves website performance for many businesses, leading to better outcomes across various metrics."

Count the facts: zero. No numbers, no names, no verifiable claims.

### Step 2: Add Specifics

Ask yourself for each claim:

- How much? (Replace "significantly" with a number)
- For whom? (Replace "many businesses" with specific segments or names)
- Which metrics? (Replace "various metrics" with named KPIs)

### Step 3: Rewrite with Density

> "The platform reduces page load time by 340ms on average (measured across 1,200 WordPress sites), improves Core Web Vitals LCP scores from 3.8s to 1.9s, and is deployed by e-commerce stores generating over €50M in annual revenue, including three Shopify Plus merchants in the DACH region."

Count the facts: 6 in one sentence. Load time reduction (340ms), sample size (1,200 sites), LCP improvement (3.8s → 1.9s), revenue scale (€50M), count (3 merchants), region (DACH).

## Fact Types That AI Systems Favor

| Fact Type | Example | Extraction Value |
|---|---|---|
| Numerical data | "61% decline in organic CTR" | Very high |
| Named entities | "Siemens, Bosch, BASF" | High |
| Dates | "Published February 2026" | High |
| Comparisons | "3.4× more likely than..." | High |
| Technical specs | "768-dimensional vector space" | Medium-high |
| Geographic specifics | "EU-hosted, Frankfurt datacenter" | Medium |
| Process steps | "Three phases: retrieval, reranking, generation" | Medium |
| Source attribution | "(Princeton NLP, Nov 2025)" | High |

## Density by Content Type

Different content types have different natural fact density targets:

| Content Type | Target Facts/500 Words | Primary Fact Sources |
|---|---|---|
| Technical documentation | 15–20 | Specs, code, parameters |
| Case studies | 12–18 | Results, metrics, timelines |
| How-to guides | 10–15 | Steps, tools, measurements |
| Industry analysis | 12–16 | Statistics, research, trends |
| Product pages | 10–14 | Specs, pricing, compatibility |
| Opinion/thought leadership | 6–10 | Citations, examples, data |

## Common Density Killers

These patterns destroy fact density. Find them and rewrite:

The filler opening:

> "In today's rapidly evolving digital landscape, businesses need to stay ahead of the curve."

Zero facts. Delete it entirely or replace with a data point.

The vague comparison:

> "Much better than the competition."

Replace with: "47% faster than Tool X's median response time (benchmarked Q1 2026)."

The emotion play:

> "We're passionate about delivering exceptional results that exceed expectations."

AI can't extract passion. Replace with evidence: "Average client sees 2.3× increase in AI citations within 6 weeks of implementation."

The adjective pile-up:

> "Our innovative, cutting-edge, industry-leading platform."

Replace all adjectives with one fact: "Processes 50,000 requests/day with 99.97% uptime."

## The 12-Fact Audit

Before publishing any page, count the concrete facts in the first 500 words. If you're below 12:

1. Replace every adjective with a measurement
2. Add named entities (companies, tools, people, places)
3. Include dates for any temporal claim
4. Cite sources for any statistic
5. Add a data table if comparing anything

This single habit — counting facts before publishing — is the highest-leverage GEO improvement most sites can make.

## Measuring Fact Density

The Zitably Score includes a Fact Density axis (/15) that uses LLM analysis to count:

- Named entities per 500 words
- Numbers and statistics per 500 words
- Verifiable claims vs. vague assertions

Run your pages through the analyzer to see where they stand and which sections need work.
