Definition & Overview

Citation Probability is a predictive metric estimating the likelihood that an AI answer engine will extract and attribute a specific passage of web content as a cited source.

Calculated based on factors like information density, presence of verified statistics, structural BLUF clarity, schema markup, and domain authority.

Analogy & Mental Model

Citation Probability is like an editor's evaluation of a manuscript: clean facts with clear footnotes are far more likely to be quoted than vague opinion pieces.

Why Citation Probability Matters

High Citation Probability content achieves consistent source links across ChatGPT, Perplexity, and Gemini, driving high-intent referral traffic.

Concrete Real-World Application

Updating a blog post with primary survey data and H2 summaries, lifting its Citation Probability score from 22% to 89%.

How Citation Probability Works

Evaluated by scoring content passages against RAG parsing heuristics.

Core Components & Mechanisms

Fact Density Scoring

Counting verified statistics, dates, and concise definitions per paragraph.

Structural Clarity Check

Verifying opening BLUF summaries and clean HTML structure.

Crawl Accessibility Audit

Ensuring server-rendered HTML and clear robots.txt permissions for AI bots.

Citation Probability vs Citation Share

Citation Share measures the overall percentage of AI queries citing your brand, whereas Citation Probability estimates the likelihood that a specific passage will be extracted for a given prompt.
