Consumer services across seven engines

Between 8 and 12 July 2026, seven assistants with live web search answered 105 prompts about 84 Portuguese consumer-service brands in seven sectors, 2,205 answers in all. A brand counts as recommended when it is presented as a suitable option in at least two of three runs, across at least three distinct prompts. The brands are anonymised by sector.

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.
  • 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 and engine, 588 rows, with the brands anonymised by sector: mentions, recommendations and citations, their rates, the average position and the sentiment. It reproduces every aggregate in the study.
