By Evren Karaarslan, Co-Founder, Brand Armor AI · Last reviewed: August 13, 2026

Marketers researching "AI share of voice" usually want a plain-language explanation — for AI share of voice, that means the practical shift, not just the definition.

Traditional share of voice (SOV) is calculated from media impressions or search rankings. AI share of voice is probabilistic — it's a percentage calculated from how often your brand appears across a sample of relevant prompts, compared to competitors. This page explains that shift from deterministic ranking (position 1–10) to probabilistic presence (appeared in 67% of relevant prompts). This is a genuinely new measurement paradigm that most marketers haven't grasped.
