Not measured yet

This sector has not been measured yet

The question set for bathrooms is ready: 8 buying questions and three personas. The index runs part of the sectors each week within a fixed budget; this one is due within 4 weeks. Until then we show no numbers here — a sample leaderboard would suggest a measurement that never happened.

The 8 questions we ask

  1. 01Waar laat ik een complete badkamer verbouwen in Nederland?

Without a brand name, in Dutch, with the Netherlands as market. The same set every week.

The personas behind the questions

  • Stel dat een complete badkamer laat verbouwen binnen zes weken
  • Senior die een badkamer levensloopbestendig wil maken
  • Koper die alleen de douche wil vervangen

Personas and questions are in Dutch: the index measures the Dutch market.

How this was measured

  • 01Every question goes to the engines through their API in a clean session: no account, no history, no personalisation.
  • 02Brand names are extracted from each answer (text extraction). Per brand the decision layer judges whether it is a real brand in this sector, whether it is a marketplace, how it is spoken about and how prominently it appears. That certainty is shown in the table.
  • 03Brands only count when the probability that they are a real brand is at least 50%. Borderline cases are left out.
  • 04Share is measured over a four-week window with a 95% confidence interval. Names that turn out to be the same company are merged once the decision layer confirms it.
  • 05Engines without a usable API (such as Google AI Overviews) are not in this index. Browser captures of consumer products follow once the capture service is publicly available; those will be labelled separately.
