Regional pages publish only where the local ranking meaningfully differs. Browse the Index →
From November 3, 2026, a country counts as crowning a different #1 only when its #1 is a different brand from the global #1: two names for the same brand, or the same brand on its own site, count as one. Earlier editions are counted the same way.
Built from the Index’s hash-frozen monthly answer corpus: each of the 9 AI models asked the buyer’s question, answers stored verbatim, brands ranked by presence only. Rankings are computed from AI responses alone and are not for sale. Read the methodology →
