Share of Voice
Share of Voice is the percentage of total mentions or visibility a brand receives compared to all mentions of competing brands in its category during a given period. It measures relative competitive visibility and market presence against rivals in earned, owned, and paid channels.
Definition
Share of Voice aggregates mentions across search results, media coverage, social platforms, advertising impressions, and other channels, then calculates a brand's portion of total category conversation. For example, if a brand receives 30 mentions out of 100 total category mentions in a month, its share of voice is 30 percent. The metric varies by channel and time period, allowing granular competitive assessment.
Marketing teams use share of voice to benchmark performance against competitors, assess the impact of campaigns and initiatives, allocate budget strategically to channels where competitors dominate, and identify windows of opportunity. Rising share of voice typically correlates with growing market awareness, customer preference, and sales momentum. Declining share of voice signals competitive threats or declining marketing effectiveness.
Why it matters for AI visibility
In the AI search era, share of voice now includes mentions in AI-generated summaries, chatbot responses, and LLM outputs. Brands that rank highly in AI visibility capture a larger share of AI-driven voice, directly influencing how AI assistants present product alternatives, recommendations, and competitive options to users making purchase decisions.
