See the GEO suiteHow this was measured
Each month we ask every assistant the same plain buyer questions, worded the way a person shopping for this kind of product would ask them, with no brand suggested in the question except where the question itself names the market leader to find alternatives to. Each assistant answers in a fresh session with no earlier conversation, so an answer reflects what the assistant says to anyone who asks, not what it was steered towards.
From each answer we keep the product and company names it recommends. A name counts only when it appears in the answer as a proper name, is not a heading such as "Best for" or "Pricing", and is confirmed by a second assistant naming it too, by a website the answer cites, or by being the market leader named in the question. Share of voice is each brand's share of all brand mentions in the category this month. Assistants that could not answer this month are listed as not answering, never counted as naming nobody.
