AI share of voice
Also known as: AI SoV
In short
A measure of a brand’s presence relative to other brands within a defined sample of AI-generated answers.
AI share of voice compares a brand’s presence with competitors in a specified set of AI answers. It is a measurement approach, not a universal platform metric.
Different services count and weight visibility differently. Some use brand mentions; others also consider where a brand appears. Always read the method behind the percentage.
A practical example
Imagine a report containing 100 counted brand mentions across a fixed set of answers. If one brand receives 20, its share is 20% under that report’s simple mention-share method.
This is an illustrative calculation, not an industry-standard formula. Counting each brand once per answer would produce different inputs from counting every occurrence. Restricting the comparison to selected competitors would also change the denominator.
Keep comparisons consistent
Record the prompt set, competitors, platforms, language, market, and collection dates. Explain whether positions receive weights and how answers with no brand mentions are handled.
A rising share can reflect a competitor losing mentions rather than your brand gaining them. Check the underlying counts as well as the ratio. AI share of voice describes the observed sample; it does not directly measure market share, customer preference, or the share of all private conversations on an AI platform.
