Share of Model
The share of AI systems that name a brand when asked a relevant question. It exists because coverage is not uniform: a company can be recommended by ChatGPT and absent from Claude, and a single-engine report will not show it. The same applies across countries. When we asked which AI visibility tool to use in the United States, Spain and France, twelve runs in total, not one tool was cited consistently in more than one market, and the stable sets did not overlap at all.
