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

The personas behind the questions

• Huishouden dat kiest tussen vast en dynamisch contract
• Eigenaar van zonnepanelen die let op terugleverkosten
• Verhuizer die een nieuw contract moet afsluiten

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

• 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.
