Share of Voice

Share of Voice (SOV) is your share of brand mentions in non-branded AI answers, measured against the competitors you track. It's the clearest way to see whether you're winning or losing organic category conversations.

#What it measures

Visibility tells you how present youare. Share of Voice puts that in context: of all the brand mentions across your non-branded prompt set, what fraction were you, versus your competitors? If five brands split the answers in your space, an even split is 20% each. More than that and you're punching above your weight; less and rivals are taking the conversation.

#How it's calculated

For a given engine and non-branded prompt set:

Share of Voice = your brand mentions
                 ÷ (your brand mentions + competitor mentions)

For example, if the latest ChatGPT snapshot contains 12 mentions of your brand and 38 mentions of tracked competitors, your SOV on ChatGPT is 24%. We calculate it per engine, then roll it up, because the same brand can have very different SOV on Perplexity versus Gemini.

#The leaderboard

AppearIn AI ranks you and your tracked competitors by SOV on a leaderboard, per engine. This is the fastest way to answer the question every team eventually asks: "when an AI recommends something in our category, who does it name, and how often is it us?"

Because it's competitive, your SOV can fall even when your own presence is flat, a competitor publishing strong new content takes share from everyone. That's why we always show SOV alongside the competitor set rather than as a lone number.

#Moving your SOV

• Find the prompts where you're absent. Coverage gaps are the biggest lever, appearing in prompts you currently miss raises SOV directly.
• See who's named instead. The leaderboard and answer transcripts show which competitor took the slot, and the sources show which pages the engine trusted.
• Track by segment.Group prompts by intent (commercial, informational) to see where you're strong and where rivals dominate.
