Know Your Share of AI Recommendations
Being mentioned is good. Being recommended more than your competitors is better. Track your Share of Model across all major AI platforms.
What is Share of Model and why does it matter?
Share of Model (SoM) measures the percentage of AI recommendations you receive versus competitors. It's calculated as: (Your Mentions / Total Market Mentions) × 100. According to marketing research by Binet & Field, Share of Voice predicts market share—if your SoV exceeds your market share, you're likely to grow.

100 mentions sounds good. But if competitors have 400 mentions, you're losing 80% of recommendations.

Frequently Asked Questions About Share of Model
Share of Model (SoM) measures the percentage of AI recommendations you receive versus competitors for relevant queries in your category. It's calculated as: (Your Brand Mentions / Total Market Mentions) × 100. This metric is the AI equivalent of Share of Voice in traditional marketing—and according to Binet & Field research, brands with Share of Voice exceeding their market share tend to grow.
Counting mentions only tells you absolute numbers (e.g., "100 mentions this week"). Share of Model tells you relative position (e.g., "28% of all category recommendations"). If you have 100 mentions but competitors have 400, you're capturing only 20% of AI recommendations—your absolute growth could mask relative decline.
