What is AI Share of Voice?

AI Share of Voice (AI SoV) is a metric that measures how often AI language models mention or recommend your brand relative to competitors when responding to relevant queries. It's the AI equivalent of traditional Share of Voice metrics used in advertising and PR.

Why AI Share of Voice Matters

As AI assistants become primary research and recommendation tools, the brands that AI mentions win. Unlike traditional search where users might explore multiple results, AI users typically act on the first recommendation.

Consider this scenario:

  • User asks: "What's the best email marketing tool for small businesses?"
  • AI responds with 5 recommendations
  • Your brand is either in that list—or it isn't

    • AI Share of Voice tells you exactly where you stand.

    How to Calculate AI Share of Voice

    AI SoV = (Your Brand Mentions / Total Brand Mentions) × 100

    Example:

  • Query: "Best project management software"
  • Total recommendations across 100 AI queries: 500 brand mentions
  • Your brand mentioned: 75 times
  • AI Share of Voice: 15%

    • Tracking AI Share of Voice

    Manual tracking is impractical due to:

  • AI response variability (same prompt can yield different answers)
  • Multiple AI platforms to monitor
  • Need for consistent, daily measurement

    • Tools like BrandVector automate this by:

  • Running queries across ChatGPT, Claude, Perplexity, and Grok
  • Analyzing responses for brand mentions
  • Calculating competitive share of voice
  • Tracking trends over time

    • Improving Your AI Share of Voice

  • Optimize citation sources: Appear on websites AI models frequently cite
  • Create comparison content: AI loves pulling from comparison pages
  • Build brand authority: Consistent, authoritative content improves AI perception
  • Monitor and iterate: Track what prompts you win/lose and adjust strategy
