What is a Share of Voice (SOV)?

Your brand's visibility in the market compared to competitors.

Understanding Share of Voice (SOV)

Share of Voice (SOV) measures your brand's visibility and presence in the market compared to competitors. It can be calculated across different channels: share of advertising spend, share of social media mentions, share of search impressions, or share of media coverage.

SOV is a relative metric that reveals competitive positioning. Research (particularly from the IPA and Les Binet/Peter Field) shows strong correlation between share of voice and market share—brands that maintain SOV above their market share tend to grow, while those below tend to shrink. Monitoring SOV helps with: competitive benchmarking, budget planning (determining whether you're investing enough to grow or maintain position), and identifying competitive threats. Calculate SOV by dividing your brand metrics by total category metrics.

Share of Voice (SOV) measures your brand's visibility and presence in the market compared to competitors. It can be calculated across different channels: share of advertising spend, share of social media mentions, share of search impressions, or share of media coverage.

Why is Share of Voice (SOV) important?

Share of Voice provides competitive context that absolute metrics miss—growing followers by 50% means little if competitors grew 200%. Research shows excess SOV (SOV greater than market share) drives market share growth at approximately 0.5% per 10 percentage points of excess SOV. This makes SOV a leading indicator of future market share, enabling proactive competitive response rather than reactive scrambling.
