# LLM Influence Score

*Measurement* · *Citation & Visibility Measurement*

## Definition

LLM influence score is a measure of how often and how prominently an AI system retrieves and cites a brand's content when it searches the live web to answer a question. It combines citation frequency, position within the assembled answer, and the share of relevant queries where the brand's content is used at all.

## Why It Matters for AI Search

Citation frequency alone does not describe influence. A brand cited once in the closing line of an answer has not shaped the recommendation. A brand whose content supplies the answer's central claim has. LLM influence score separates presence from weight, which matters because retrieval is competitive: for any given question a model assembles its answer from a small set of sources, and the ones it draws on most heavily determine what the buyer is told. Tracking influence rather than raw citation count also reveals which content formats and structures are being drawn on, making the metric actionable rather than merely descriptive.
