What is Share of Model and why is it important for your brand?

Definition and relevance in the era of generative AI

Share of Model (SoM) is a metric that quantifies how often a brand or product appears in responses generated by language models (LLMs) like GPT-4, Gemini or Claude. Share of Voice (SoV) measures visibility in traditional search engines; SoM, in conversational assistants. It matters because these models are becoming the gateway to information: according to Gartner, by 2026, 30% of digital interactions will run through generative AI. If your brand does not appear, you lose business opportunities. In Spain, where ChatGPT adoption exceeds 40% among digital users, ignoring this metric is a risk.

Practical steps to audit your AI visibility

Measuring Share of Model takes a systematic approach. First, define the queries your potential customers would ask an AI assistant.

Then query several models (ChatGPT, Bard, Bing Chat) and record the responses. You can do it by hand or with tools like Brand24 (AI mention monitoring) or Semrush (which includes AI visibility analysis). There are also startups like MarketMuse with topic authority metrics. Calculate the percentage of times your brand appears. Good practice: repeat the audit every month to see trends.

What strategies improve Share of Model in Spain?

Optimize your content to be mentioned by AI

To improve your Share of Model, work on three pillars: authority, relevance and structure. AI favors sources with high authority (E-E-A-T), so earn backlinks from reputable sites and update your content regularly. Use structured data (schema.org) so models understand your information better. Create localized content for Spain: geographic references, local success stories and mentions of Spanish regulations. Take part in forums and communities where AI can pick up on your expertise. According to a Statista study, 65% of users trust AI responses if they cite recognized sources. So publish in authoritative media like El País or Expansion.

«Share inside model answers grows from repetition, not volume. The same fact about a company must appear in its profile, on its site, in directories and in reviews, worded the same way each time.»
