Retail panel data

Sales data collected from retailers' checkouts by research firms such as NielsenIQ and Circana, and sold to brands to track sales, prices, distribution and market share.

Why it matters

It lets brands compare themselves with competitors. Coverage varies: not every retailer shares its data.

In Switzerland

NielsenIQ's Swiss Markt Monitor is based on more than 40 large retailers, together about 40–50% of retail sales (NielsenIQ, 4 Feb 2026).
