This sector has not been measured yet
The question set for windows and frames 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.
prompt set v1
The 8 questions we ask
- 01“Wat kosten kunststof kozijnen voor een rijtjeshuis?”
- 02“Welke leverancier van kozijnen is betrouwbaar in Nederland?”
- 03“HR++ of triple glas: wat is verstandig bij een matig geïsoleerd huis?”
- 04“Waar laat ik enkel glas vervangen door isolerend glas?”
- 05“Welke kozijnen zijn het beste tegen geluid van een drukke straat?”
- 06“Welke bedrijven leveren kozijnen met montage en garantie?”
- 07“Kunststof of houten kozijnen: wat gaat langer mee?”
- 08“Waar kan ik kozijnen laten vervangen met subsidie?”
Without a brand name, in Dutch, with the Netherlands as market. The same set every week.
The personas behind the questions
- Huiseigenaar die enkel glas wil vervangen door HR++
- Koper die kiest tussen kunststof en hout
- Bewoner van een drukke straat die geluidsisolatie zoekt
Personas and questions are in Dutch: the index measures the Dutch market.
Full method
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.
