It indicates the competitive position in AI answers.Open glossary entry → (SoV) describes a brand's relative presence versus competitors in AI answers. A brand can rank solidly in classic Google search and still be mentioned less often than a competitor in ChatGPT or Perplexity.

• Competitor A: 40 percent of mentions,
• Competitor B: 25 percent,
• own brand: 15 percent,
