What best sellers have in 9 categories and 4 countries

How today's best-selling products in a category differ from others picked at random from further down the ranking. First, what the listing looks like; separately, in grey, what depends on the store (who sells, variations, brand, price). It is a first look, not the full study: if a category interests you, request it and we will study it in depth.

How to read it

“Best sellers today” mixes veteran and new products: it describes what today's best sellers are like, not what makes a launch win. It is correlation, not causation, and it has not been checked with new products. We only show clear differences: a 95% interval that does not cross zero, at least 10 points of difference and correction for multiple comparisons. These profiles do not count as validated findings.
