Every month, the Index measures which brands appear in the answers of ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews across five sectors, in Portugal and Spain. Each brand gets a single score: the average across all engines. The first edition is published on 2 November 2026.
The five sectors in the first edition
- Banking and insurance
- Tourism
- Healthcare
- Education
- Technology
How it’s calculated
For each sector and market, we ask every engine a fixed set of real consumer questions. We count which answers mention each brand and average the results across engines. The result is one score per brand, comparable from month to month.
The method follows the same rules as the platform: questions grouped by intent, more than one round of questions and the same question set every month, so that changes are real and not down to chance.
