Brand inclusion rate
Definition
Brand inclusion rate measures how often AI-generated answers include your brand across a tracked set of prompts. Expressed as the percentage of relevant prompts in which your brand appears at all — cited or merely named — it is a baseline AI visibility metric that answers a simple question: when buyers ask AI about your category, how often do you show up?
How it works
Brand inclusion rate is computed by running a defined prompt set across AI platforms and recording, for each prompt, whether your brand appears in the answer. The rate is the share of relevant prompts where it does.
The formula:
Brand inclusion rate = (Prompts where your brand appears ÷ Total relevant prompts) × 100
Inclusion counts any appearance — a cited link, a named mention without a link, or a listing among recommended options. That breadth is deliberate: the metric measures presence, not the quality or prominence of that presence. Because answers vary by engine and by run, inclusion rate is most reliable when measured per engine and averaged over multiple runs and a rolling time window.
Why it matters
Inclusion is the entry condition for everything else. A brand that is never included in AI answers can't earn citations, can't shape sentiment, and can't drive AI-referred traffic. Brand inclusion rate is the floor metric that tells you whether you're even in the consideration set AI presents to buyers.
Tracked over time and against competitors, it becomes a leading indicator of category presence. A rising inclusion rate means AI engines are increasingly surfacing your brand when buyers ask relevant questions; a competitor's higher inclusion rate signals they're owning more of the prompt space. Because it's simple and intuitive, inclusion rate is often the first metric teams baseline before layering on citation share, sentiment, and share of voice.
Frequently asked questions
How is brand inclusion rate different from citation share?
Inclusion rate counts any appearance of your brand in an answer, including unlinked mentions. Citation share counts only answers that cite your domain as a source. A brand can have a high inclusion rate but low citation share if it's mentioned often but rarely cited as the evidence behind the answer.
Does an unlinked mention count toward inclusion rate?
Yes. Inclusion rate measures presence of any kind, so a brand named in an answer without a citation link still counts. Unlinked mentions matter because buyers who hear a brand in an AI answer often search for it directly afterward.
What is a good brand inclusion rate?
It depends on category breadth and competition, and the meaningful comparison is always relative to tracked competitors rather than an absolute threshold. A 70% inclusion rate is strong if rivals sit at 40%, and weak if they sit at 90%. Track the trend and the competitive gap rather than chasing a fixed number.
Should inclusion rate be measured per engine?
Yes. The same brand can be included in most ChatGPT answers and few Perplexity answers for the same prompts, because engines retrieve and weight sources differently. A per-engine view reveals which platforms you're missing from; an aggregate hides it.
Citation share
Citation share is the percentage of relevant AI answers that cite your domain as a source. Measured across a tracked prompt set, it is a north-star GEO metric: it ties AI visibility directly to authority and downstream traffic by counting not just whether your brand is mentioned, but whether AI engines treat your pages as the evidence behind their answers.
AI share of voice
AI share of voice is your brand's proportion of mentions in AI-generated responses relative to competitors, measured across a defined set of prompts and platforms. It adapts the traditional share of voice metric for AI search — where visibility lives inside chat answers and AI Overviews rather than ranked links or media impressions.
AI brand mentions
AI brand mentions are the instances of your brand name appearing inside responses generated by AI assistants — ChatGPT, Claude, Gemini, Perplexity, Grok, and Google AI Overviews. Unlike traditional brand monitoring across social and press, AI mentions surface inside the answer a buyer is reading, making them a high-leverage demand signal for Generative Engine Optimization (GEO).
Share of model
Share of model is the percentage of relevant AI-generated answers in which your brand appears, measured across a defined set of prompts and platforms. It is the AI-search equivalent of share of voice and the headline metric for tracking GEO performance.
AI search visibility
AI search visibility is the umbrella metric capturing how often, how prominently, and how favorably your brand appears across AI assistants — ChatGPT, Claude, Perplexity, Gemini, Grok, and Google AI Overviews. It bundles mentions, citations, ranking position, sentiment, and AI-referred traffic into the executive-level read of a brand's standing in AI search.
Prompt monitoring
Prompt monitoring tracks how AI systems answer a controlled set of customer prompts over time — recording mentions, citations, sentiment, and accuracy in each response. By re-running the same prompts on a schedule across engines, it turns the stochastic, shifting behavior of AI answers into a continuous time series that surfaces when and how your brand's visibility or framing changes.
