What winning products on Amazon have, and what yours is missing

We track thousands of launches from their first day, read every listing with AI and measure which ones end up among the best sellers. We show you the patterns that repeat and what your listing is missing to look like the winners.

Match

Compare your listing with the launches that won, backed by a sealed exam.

Why one is instant and the other takes longer

Wintraits Scan Index and Wintraits Match Index

One you get instantly; the other takes longer, but tells you much more

Both give a number from 0 to 100 and mark it with a bar on a ruler: the further right, the closer your listing is. What changes is what they compare it with, and that decides how long they take and how much they tell you.

Best sellers 71-90Rest 28-69

Example listing scoring 78 in manual shaving, Amazon Spain: falls within the best-seller band.

  • What it compares with. With today's best sellers in your category, against products further down the ranking.
  • Why it is instant. It only needs the listings selling today, so there is nothing to wait for. That is why it already covers 11 categories and you get yours free in seconds.
  • Its limit. It is a snapshot of today. Many best sellers have been on top for years: it tells you what they have, not whether it helped them get there.

Wintraits Match Index · after 6 months of tracking

Example listing scoring 60.

  • What it compares with. With the launches that ended up in the top 20% sellers of their quarter.
  • Why it takes longer. We track every launch from day one for 6 months, until we know which ones succeed, and we seal the exam before seeing the result. That is why it only covers 2 categories today.
  • Why it is far more complete. It does not reward whoever has been selling for years, but whoever takes off. It is checked against launches the model did not see while learning, and the diagnosis tells you what to change first and how much your index would rise.

They measure resemblance, they don't promise sales: it is a correlation, not a cause. What is the difference

How it works

Five steps, always the same in every category. No opinions: only what repeats in the data.

01

We track every launch

From its first day on Amazon: price, sales rank, deals and coupons, data point by data point.

02

AI reads every listing

Title, bullet points and description: ingredients, benefits, claims, format, images… It all becomes data.

03

We measure who wins

Winner = the top-selling 20% of its launch quarter, between days 60 and 180.

04

Sealed exam

The model is frozen and tested once only on products launched later. We publish the result whatever it is; if it fails, Match is shown as descriptive.

05

Your diagnosis

We compare your listing with the winners and tell you which changes bring it closest to them.

What we measure to say a product “wins”

Start We measure its sales rank here (median) After
day 0 · launch day 60 day 180

We compare each product only with those launched in the same quarter. The top 20% are the “winners”. That way we do not reward whoever has been selling for years, but whoever takes off.

Who it is for

Brands and manufacturers

Before launching or reformulating: which attributes and combinations repeat among the products that take off in your category.

Sellers and agencies

Review listings in seconds and prioritise the changes that bring them closest to the winners. Also via API, for many listings at once.

AI agents

Connect your assistant via MCP: it looks up the winning patterns and diagnoses listings on its own, with the same data as the website.

Frequently asked questions

Will I definitely sell more?

No. They are statistical patterns of the products that won: correlation, not causation. That is why you should only apply changes that are true of your product.

What exactly is a “winner”?

Winner = a product in the top 20% of the sales rank of its launch quarter (median of days 60 to 180). “Times more frequent” = how many times more often the attribute appears among winners than among all products (1.5 times = 50% more). Only those that hold up when checked with products launched after the ones used to discover them are included.

Where does the data come from?

From the marketplaces' public history (price, sales rank, deals) and the text of the listings. We only publish aggregated results, never data on specific products.

What do you do with my listing?

We analyse it to give you the diagnosis and then forget it: we do not store it. We use no tracking or advertising cookies.

How much does it cost?

You can use it for free: Free and unlimited during the beta, until 31-Jan-2027. After that, 5 free full queries (2 without signing up and 3 with a free key). Sign up during the beta for founder pricing: −50% for 12 months. To prevent abuse there is also a cap of 30 diagnoses a day. Paid plans will open soon: see “Planned pricing”.

What is the difference between Scan and Match?

Scan is a snapshot of what today's best sellers have: fast and across many categories. Match follows every launch from day one, checks it with a sealed exam and is the only one that diagnoses your listing; that is why only some categories offer a diagnosis.

Can I use it from my AI assistant?

Yes: we have an MCP server and an API. Under “AI agents and API” you will find the address and a free key.

How similar is your listing to the winners?

Paste the title, bullet points and price. In a few seconds you will know its Wintraits Match Index and what to change first.
