AI Citation Share is the proportion of relevant AI answers in which a brand is cited or recommended, measured across engines and a tailored question set.
AI Citation Share is the proportion of relevant AI answers in which a brand is cited or recommended. It is measured across the three engines and a tailored set of questions that reflect how real buyers ask. A higher share means the brand appears in more of the answers that matter, rather than just ranking somewhere on a page.
Presence is binary in an AI answer: a brand is either named or it is not. AI Citation Share turns that into a measurable proportion, so a business can see how often it makes the cut across the questions its buyers actually ask.
It is also a share, which means it is relative. If a competitor is cited in eight answers out of ten and you appear in two, the gap is plain. That comparison is hard to see by reading answers one at a time.
Because the engines reach a wide and growing audience, OpenAI reported in December 2025 that 900 million people use ChatGPT every week, a small change in citation share can map to a large change in how many buyers hear about a business.
K&C measures AI Citation Share inside an AI Visibility Strategy. We build a question set tailored to the brand and its buyers, run it across the three engines, and record how often the brand is cited or recommended.
That share feeds the AI Visibility dimension of the AI Visibility Score, which carries 40 per cent of the weight. It answers the first question any business has: do the engines mention me at all, and how often.
We always read the figure against competitors, so a brand can see its share of the conversation rather than an isolated count. The detail sits in our methodology.
