Frequently asked

What is Share of Model (SoM) in AI search?+

Share of Model (SoM) measures the percentage of buyer-intent prompt responses where your brand is cited versus named competitors across major LLMs (ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews).

How is Share of Model calculated?+

SoM is calculated by testing a benchmark cluster of 50 to 500 category prompts across multiple AI engines, recording total brand citations, and dividing your brand mentions by the total number of category recommendations.

Why is Share of Model more important than keyword rank?+

Keyword ranks only reflect blue-link position on traditional Google. When users ask conversational questions in ChatGPT or Perplexity, they are shown a single synthesized answer with 2-4 citations. If your Share of Model is 0%, your brand is completely invisible to conversational buyers.
