In marketing, share of voice measures a brand's visibility relative to its competitors within a specific market or channel. It reflects how much attention a brand captures compared to others, helping marketers understand their competitive presence and how that presence changes over time.

Share of voice provides a measurable way to evaluate whether an activation generates interest beyond the event itself. In experiential, positive feedback and social buzz only tell part of the story. Tracking changes in branded search interest helps reveal whether consumers are actively looking for a brand after encountering it.

For Share of Voice, Gradient focuses on three measurement checkpoints. Search interest is measured against key competitors in the weeks before an activation to establish a baseline. Immediately afterward, the same measurement reveals any increase in relative search interest. A final check 30 days later shows how much of that lift remains. Together, these checkpoints distinguish an immediate spike from sustained brand interest.

An activation can generate significant attention during its launch week, but the more meaningful question is whether people continue seeking out the brand afterward. A 45% increase in Google search share of voice one week after an activation demonstrates how an experience can drive active consumer interest. Measuring again a month later helps determine whether that impact extends beyond the moment itself.
