What excess share of voice predicts
Excess share of voice (ESOV) is the gap between a brand's share of voice (its share of category advertising and attention) and its share of market. The concept, rooted in research from Les Binet and Peter Field, holds that when a brand's share of voice exceeds its share of market, it tends to grow, and when it falls below, it tends to shrink. ESOV turns a fuzzy idea, "advertise more than your size suggests to grow", into a measurable, planning-useful relationship between how loud a brand is relative to competitors and its expected trajectory.
Why it guides budget
ESOV is useful because it links investment to growth in a way budgets can act on: to grow share, a brand generally needs to maintain a share of voice above its share of market, with the size of the excess roughly relating to the rate of growth. This reframes advertising budget as a competitive variable, what matters is your voice relative to competitors, not just your absolute spend, and it argues against under-investing to the point where a brand's voice drops below its market share and erodes. It also implies that smaller challengers must punch above their weight in share of voice to take share from larger incumbents.
The discipline
The disciplined approach uses ESOV as a planning guide, measuring share of voice relative to competitors and to your own market share, and maintaining a positive excess to support growth rather than letting voice fall below market share where decline tends to follow. Treat it as a directional relationship informed by evidence, not a precise formula, and pair it with brand and demand measurement. The trap is setting ad budgets in absolute terms while ignoring competitive share of voice, under-investing into decline or misjudging what growth requires; the discipline is planning voice relative to the market, since the evidence suggests that being heard more than your size predicts, sustainably, is a real lever on whether a brand grows or shrinks.
