Share of Model
Your brand's portion of all AI recommendations made within a category, expressed as a percentage of total brand mentions across a test set.
Analogy Mental model
An assistant recommends three hundred restaurant slots across a hundred diners. You take sixty, your rival takes ninety, so your share is a fifth and theirs is nearly a third.
In practice What you actually do
Divide your mentions by the total mentions of every brand that appeared, not by the number of prompts. That distinction matters: the first measures your weight in the conversation, the second only measures how often you are discussed at all.
Where people get burned Pitfalls
Report both figures and never conflate them. A brand can appear in most prompts yet rank low in each, which reads as presence when the commercial reality is that it is always the third option.
