Share of Voice (SOV) and Its Correlation with Market Share
Share of Voice (SOV) measures your brand’s exposure and visibility in the market compared to your competitors. Historically tracked in print and TV ad spend, modern digital SOV spans organic search clicks, social media mentions, and paid search ad impressions.
Businesses track SOV because it has a strong, proven correlation with market share. A brand whose SOV is higher than its current market share (Excess Share of Voice or ESOV) is highly likely to experience market share growth over the subsequent 12 to 24 months.
