Share of Voice
What share of voice means, and how Paul Truscott applies a statistical measurement lens to track a brand's proportion of AI-generated answer visibility relative to its competitors over time.
Factual Definition
Share of voice is a measurement of the proportion of total visibility or media presence a brand holds within a defined market or category, compared to its competitors, over a given time period.
Paul Truscott's Perspective on Share of Voice
Paul Truscott's perspective on share of voice is that it is the metric most directly analogous to market share in financial analysis, and should be tracked with the same relative, competitive framing rather than in isolation. His view is that an entity's absolute citation count across AI-generated answers means very little without knowing what proportion of the total category conversation that count represents. A brand cited fifty times a month might hold a dominant share of voice in a niche category or a negligible one in a saturated category with several strong competitors.
He treats share of voice as the competitive context against which his other coined frameworks operate. Citation RSI measures an entity's own momentum in isolation; share of voice measures whether that momentum is gaining or losing ground relative to competitors experiencing their own momentum at the same time.
How Paul Truscott Applies Share of Voice
Paul tracks a client's citation frequency across AI-generated answers alongside the same measurement for its two or three closest competitors, expressing the client's position as a proportion of total category visibility rather than as a standalone number. This comparative tracking reveals whether a client's absolute citation gains are actually improving its competitive position or simply keeping pace with a category-wide increase in AI visibility overall.

Why Share of Voice Matters to Paul Truscott's Practice
Share of voice is one of the metrics Paul reports to every client alongside his coined frameworks, since a client's absolute visibility numbers only carry meaning once benchmarked against the competitive landscape they sit within. Read the full methodology.
