What Is Share of Model and Why It Matters for Your Brand

The Rise of AI-Powered Search

Artificial intelligence is transforming how people discover brands. When someone asks ChatGPT, Perplexity, or Google's AI Overview for a product recommendation, the AI draws from its training data and real-time sources to generate a response. If your brand isn't being mentioned, you're invisible to a growing segment of your audience.

This is where Share of Model comes in.

What Is Share of Model?

Share of Model is a metric that measures the percentage of times your brand is mentioned by AI models compared to all brands in your category. Think of it as the AI equivalent of Share of Voice in traditional media.

For example, if an AI model responds to 100 marketing-related prompts and mentions your brand in 25 of those responses while mentioning competitors a combined 75 times, your Share of Model is 25%.

The Formula

Share of Model = (Your Brand Mentions / Total Brand Mentions) × 100

Why Share of Model Matters

1. AI Is Becoming the New Search Engine

Millions of people now use AI assistants as their primary information source. If your brand isn't part of the AI's response, you're missing out on a rapidly growing discovery channel.

2. First-Mover Advantage Is Real

Brands that optimize for AI visibility now will have a significant head start. AI models learn patterns — the more your brand appears in quality content, the more likely it is to be recommended.
