THE RESULT

20% of mentions become a choice when the question is about the best Portuguese brands. Being named is not being chosen.

WHAT STOOD OUT
  1. In supermarkets, 96% of mentions are choices.
  2. Rewording the banking question reverses the ranking. Santander is chosen in 36 of 39 answers to a top-5 request and in 7 when the customer is thinking of switching banks.
  3. Marketeer published the study on 6 September 2026, under the title “EDP is the Portuguese brand AI chooses most. See the ranking”.

The methodology is not a promise. It is published.

  • The question is fixed before the dataWhat counts as a mention, and what counts as being chosen, is written down before a single answer is read. Deciding afterwards is how a study finds what its author was hoping for.
  • Names that are also common words are counted by readingIn Portuguese, NOS is also "in the", ERA is also a verb, and Logo is also the word for "soon". Those are counted by reading the sentence, not by matching a string, and the exceptions are listed.
  • Published numbers come from code, not from a conversationEvery figure now comes from a script anyone can run again, with the denominators defined in one place and the result in version control, so a later run shows the difference as a diff.
  • The denominator is always statedA percentage without the number it was taken from is not a finding. Where a question could not be measured, it is said, and it is kept out of the ratio rather than counted as a zero.

Raw CSV. Redo the math.

One row per brand per question: how many answers name it, how many choose it, and the conversion between the two. Plus the totals by question, the banking question in four wordings, the most cited domains and the weaknesses each assistant declares.
