Quick answer
Share of Model (SoM) measures the percentage of times your brand is cited in generative AI responses. By 2026, it is estimated that 40% of searches will be answered by AI (Gartner). Optimize your content with structured data, expert citations, and direct answer formats to increase your SoM.
Share of Model (SoM) is an emerging concept in SEO for generative AI. Unlike traditional Share of Voice (SOV), which measures visibility in search engines, SoM quantifies direct citations in models like ChatGPT, Gemini, and Claude. With the mass adoption of generative search in 2026, brands must adapt their content to be referenced by these AIs. This article explains how to measure SoM, what tools to use, and what content strategies to implement to improve citations. Data from Statista and Gartner on the growth of generative AI are included.
Measuring Share of Model requires a systematic process. First, define a set of questions or prompts relevant to your industry. Then, use AI monitoring tools like Brand24 or Mention, which already include generative model tracking. You can also use custom scripts with OpenAI, Google, and Anthropic APIs. Calculate the percentage of responses where your brand appears out of total prompts. According to a 2026 Statista study, 35% of companies already monitor their SoM quarterly.
