Quick answer
Share of Model (SoM) measures the percentage of times your brand is cited in generative AI responses. By 2026, an estimated 40% of searches will be answered by AI (Gartner). To raise your SoM, prepare your content with structured data, expert citations and direct answers.
Share of Model (SoM) is a new concept in SEO for generative AI. Traditional Share of Voice (SOV) measures visibility in search engines; SoM quantifies direct citations in models like ChatGPT, Gemini and Claude. With generative search going mass-market in 2026, brands have to prepare their content so these AIs reference it. This article explains how to measure SoM, which tools to use and which content strategies raise citations. It includes Statista and Gartner data on the growth of generative AI.
Measuring Share of Model is done in steps. First, define a set of questions or prompts relevant to your industry. Then use AI monitoring tools like Brand24 or Mention, which already track generative models. Custom scripts with the OpenAI, Google and Anthropic APIs work too. Calculate the percentage of responses where your brand appears out of the total prompts. According to a 2026 Statista study, 35% of companies already check their SoM every quarter.
In 2026 there are several tools for measuring citations in AI models. Brand24 has an AI module that tracks mentions in ChatGPT, Gemini and Claude. Mention has added support for generative responses. For finer control, the official APIs work: OpenAI API (ChatGPT), Google AI API (Gemini) and Anthropic API (Claude). SEMrush and Ahrefs are building SoM metrics into their dashboards. According to Gartner, 60% of marketing companies will use these tools by 2027.
| Tool | Models Covered | Monthly Price | Estimated Accuracy |
|---|---|---|---|
| Brand24 | ChatGPT, Gemini, Claude | 100-500 € | 85% |
| Mention | ChatGPT, Gemini | 150-400 € | 80% |
| Custom APIs | All (customizable) | Variable cost | 95% |
To raise your Share of Model, create content that AIs consider authoritative and easy to cite. Use structured data (schema.org), answer direct questions with lists and tables, and cite verifiable sources like Statista studies or Gartner reports. And keep the content current: AIs prefer recent information. According to a 2026 Think with Google study, content in question-answer format is 50% more likely to be cited. Clear definitions and concrete examples help too.
