What today's best sellers in each category have
Scan is a snapshot of the podium. We compare the products that sell the most today in an Amazon category with others in the same category that sell less, and show you what the ones at the top have in common: how many images, which promises, what price, which certifications.
What Scan is and where the attributes come from
- We pick the category and two groupsFor example, in eye creams: today's 164 best sellers and 198 products from the same category picked at random from further down the ranking.
- We read every listingWhat can be counted is measured without AI: images, video, title and description length, price. What has to be understood (promises with figures, certifications, ingredients) is read by an AI with a definition of when it is a yes and when it is a no.
- We compare the two groupsFor each trait, what share of the best sellers has it and what share of the rest. If the top ones have it much more often, it is a best-seller attribute.
- We only publish what is clearA 95% interval that does not cross zero, a gap of at least 10 points, correction for multiple comparisons and, for what the AI reads, a second reading by another model that must agree on 90% of the listings.
Three of the attributes that most set its best sellers apart: what share of each group has them. See the category

“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. That is why the Scan check only compares your listing with today's best sellers; to see how close it is to the launches that succeeded, there is Match. Scan publication rules

“Promises a result with figures” is more common among best sellers in 8 of 11 profiles. In how many Scan profiles each listing trait appears more among the best sellers than among those that sell less.
The Wintraits Scan Index: how close a listing is to the best sellers
From those attributes we calculate a number from 0 to 100. Every attribute the listing has adds points; the ones that most separate the best sellers from the rest add more. This is how it looks with an example listing:
A made-up eye creams listing on Amazon Spain, with 14 of the 15 traits that set the best sellers apart.

Each segment is a trait and its width is how much it weighs in this category. Orange segments add up; grey is what it is missing to reach 100.
- What it measures. From 0 to 100, how close a listing is to today's best sellers in its category. Each trait that sets them apart adds more the more it separates them from the rest.
- How to read it. The blue band is where the middle half of best sellers falls; the grey one, the rest. If your number falls in the blue band, your listing already looks like the best sellers'.
- What it is not. A probability of sales. It describes what today's best sellers have: add a trait only if it is true of your product.

“Promises a result with figures” is more common among best sellers in 8 of 11 profiles
How to read each figure: we look at what percentage of best sellers has the trait and what percentage of the reference (products picked at random from lower in the ranking), and subtract the two percentages. For example, if 64% of best sellers and 40% of the reference have it, the cell says +24 (64 − 40). blue: clearly more among best sellers; orange: clearly more in the reference; grey: differences that do not pass our rules. That is why a +18 can stay grey and a +11 turn blue: to mark it, the gap must be 10 points or more, the trait must appear at least 1.5 times more often in one group than in the other (85% vs 67% does not make it; 15% vs 4% does) and it must not be explainable by chance given that category's sample size. Hover over a figure to see the subtraction and the reason.
