    "long_def": "Share of model (closely related to 'AI share of voice') measures a brand's slice of the AI conversation: if models mention brands 100 times across tracked prompts and a brand accounts for 25, its share is 25%. It is the headline output of GEO/AEO measurement tools (Profound, Ahrefs Brand Radar, Semrush) and reframes visibility from rankings to presence inside model answers.",
