What is Share of Voice?

Why It Matters

Share of voice gives brand and marketing teams a way to measure competitive standing beyond just their own numbers in isolation, since a brand's mentions or ad presence only really means something in the context of how much attention competitors are also capturing. Comparing it against actual market share reveals a useful gap, a brand with share of voice ahead of its share of market is generating more attention than its current sales reflect, which is often read as a leading indicator that revenue growth could follow. The reverse gap, share of market ahead of share of voice, can signal a brand coasting on existing reputation while losing ground in current visibility, a warning sign worth acting on before it shows up in sales. Because it can be measured across paid media, organic mentions, or social conversation, it also lets a team see whether a competitive edge is being built through spend, earned attention, or genuine cultural presence. Tracking it over time against the same competitive set turns brand awareness, normally hard to quantify, into a number that can be watched trend up or down.

Example

A brand records 8,000 social mentions in a month, while the total mentions across itself and its three main competitors add up to 40,000. Share of voice is 8,000 divided by 40,000, times 100, which equals 20%. If that brand also holds roughly 20% market share, its share of voice and share of market are in balance, but a brand with 20% share of voice and only 10% market share is generating more attention than its current sales reflect, a gap often used to argue that brand awareness is ahead of, or a leading indicator for, revenue growth.

Frequently Asked Questions

• What sources of data can be used to measure share of voice?

  Paid media spend or impressions, organic social mentions, press coverage, and search visibility are all common inputs, and different teams choose the mix that best fits what they're trying to measure.

• How does share of voice differ from market share?

  Market share measures actual sales or revenue captured relative to competitors. Share of voice measures attention and visibility, and comparing the two reveals whether a brand's awareness is ahead of, behind, or in line with its actual sales performance.

• What does it mean when share of voice is higher than market share?

  It suggests the brand is generating more attention than its current sales reflect, which is often interpreted as a leading indicator that market share could grow to catch up with that awareness.

• Who is typically included in the competitive set for share of voice?

  The brand's most direct competitors in the same market or category, chosen so the denominator represents the realistic pool of attention the brand is actually competing for.

• How often is share of voice tracked?
