AI visibility is the frequency and prominence with which your brand, product, or content appears in responses generated by large language models — ChatGPT, Gemini, Claude, and Perplexity. High AI visibility means AI models consistently recommend and cite your brand when answering relevant questions.
AI visibility measures how present your brand is in AI-generated answers. Unlike traditional SEO rankings (position 1–10), AI visibility is measured as a percentage of relevant queries where your brand appears — your Visibility Score.
Why AI visibility is the new share of voice
More than 30% of product research now starts in an AI assistant, not a search engine. When a buyer asks ChatGPT "what's the best GEO tool?" and your brand is absent, you lose that lead — regardless of your Google ranking.
AI visibility is the metric that captures this. A brand with 80% AI visibility appears in 8 out of 10 queries in its category. A brand with 5% visibility is effectively invisible to AI-assisted buyers.
