Citation Share

Citation Share is the AI-era equivalent of Share of Voice: the percentage of category-level AI citations your brand owns versus competitors. If your brand is cited 27 times in a scan while a competitor is cited 18 times, your Citation Share is 27 ÷ (27+18) = 60%. Citation Share differs from traditional Share of Voice (which counts social mentions or media coverage) in that it measures only AI-engine output — the answer surface where buyers increasingly make purchase decisions. Citation Share is the metric to track when measuring competitive positioning in AI answers, not absolute visibility.
