AI Share of Voice (AI SOV)

AI Share of Voice (AI SOV) is the percentage of AI-generated responses that mention a brand, out of all AI responses to a defined set of relevant industry queries, benchmarked against how often competitors get mentioned for the same queries.

Why it matters

AI Share of Voice is the AI-era evolution of the classic share-of-voice metric agencies have tracked for decades, adapted for a world where the competitive battlefield is a chatbot's answer instead of a search results page or an ad slot. It's the headline metric VizibleAI's platform tracks across ChatGPT, Claude, Gemini, and Perplexity.

• Share of Model

  Share of model measures the number of mentions a brand receives from one or more specific large language models, expressed as a proportion of total brand mentions across the whole category, for a given set of queries.

• Citation Rate

  Citation rate is the percentage of relevant AI-generated answers that cite a brand's domain as a source, out of every answer where citing that brand would have been relevant. It's the most commonly cited single performance metric across the GEO and AEO industry.

• Mention Rate

  Mention rate is how often a brand appears in AI-generated responses across a defined set of relevant queries, expressed as a percentage, independent of whether that appearance counts as a formal, linked citation.

• Generative Engine Optimization (GEO)

  Generative Engine Optimization (GEO) is the practice of structuring and positioning content so generative AI systems, including ChatGPT, Perplexity, Gemini, and Claude, retrieve it, quote it, and cite it when answering a question, rather than optimizing for a ranked list of links the way traditional SEO does.
