Share of Voice (SOV)
Share of voice measures how much of the visibility for a keyword set your app captures relative to all competitors.
Share of voice (SOV) in ASO quantifies how much of the available visibility across a set of keywords your app captures versus competitors. It weights your rankings by the search volume of each term, so ranking #1 for a popular keyword contributes far more SOV than ranking #1 for an obscure one.
SOV turns a scattered list of individual rankings into a single competitive scoreboard, making it easy to see whether you’re gaining or losing ground in your category overall. It’s especially useful for tracking the impact of an ASO campaign over time.
The AI-era analog, prompt share of voice, applies the same idea to mentions inside LLM answers.
