What is Share of Model Tracker?
A Share of Model Tracker is the measurement engine behind the Share of Model metric. It automates what would otherwise be a prohibitively manual process: running dozens or hundreds of queries through multiple AI engines, reading each response, identifying brand mentions, and calculating the percentage of responses that mention each brand.
The core workflow of a Share of Model Tracker involves three stages. Query execution runs the configured query bank through each target AI engine at scheduled intervals (typically weekly or monthly). Response analysis uses natural language processing to identify brand mentions, categorise mention types (recommendation, comparison, factual reference), and record the competitive landscape of each response. Metric calculation aggregates the results into Share of Model percentages per brand, per engine, per query category, and overall.
Advanced Share of Model Trackers provide segmentation capabilities that reveal insights beyond the headline number. Engine segmentation shows SoM per AI platform, revealing where a brand is strong and where it is weak. Category segmentation breaks SoM down by query intent (informational, comparative, transactional), showing which types of questions trigger brand mentions. Temporal segmentation tracks SoM changes over time, correlated with content changes, model updates, and competitive actions.
The tracker also enables competitive benchmarking at scale. Rather than monitoring your own brand alone, a Share of Model Tracker simultaneously calculates SoM for all detected competitors, providing the competitive context necessary to evaluate whether a 25% SoM is strong (if competitors average 10%) or weak (if the category leader holds 60%). This competitive lens transforms raw percentages into strategic intelligence.
For AEO programmes, the Share of Model Tracker is the most fundamental measurement tool. It provides the recurring data feed that powers trend analysis, competitive alerts, and content strategy evaluation. Without automated tracking, teams resort to manual spot-checks that provide anecdotal rather than systematic data, making it impossible to reliably measure AEO programme performance or justify continued investment.
Why it matters
Share of Model is the foundational AEO metric, but calculating it manually is impractical. A Share of Model Tracker provides the automated, repeatable measurement infrastructure that makes ongoing AEO management possible. Without it, brands cannot systematically track their AI visibility or benchmark against competitors.

Share of Model
metricShare of Model (SoM) measures how frequently a brand is mentioned or recommended by AI engines in response to relevant queries. It is the AI-era equivalent of Share of Voice, quantifying your brand's presence across ChatGPT, Perplexity, Gemini, Claude, and other answer engines.
Query Bank
toolA Query Bank is a curated collection of search queries used to systematically measure AI engine visibility. It represents the questions your target audience asks AI engines about your product category, used as the basis for calculating Share of Model and other AEO metrics.
Competitor Visibility
metricCompetitor Visibility in AEO measures how often and how favourably your competitors appear in AI engine responses compared to your brand. It provides the competitive context necessary to understand whether your AI visibility position is strong, weak, or at risk.
Brand Visibility Score
metricBrand Visibility Score is a composite metric that aggregates Share of Model, Citation Rate, mention sentiment, and citation position into a single number representing a brand's overall presence and standing across AI engine responses.
