How to find winning products: a data-first checklist

Nobody outside a brand sees its sales. What you can see is how it behaves: which ads it keeps paying for, what people search for, and how crowded the market is. Here is the checklist we use.

1. Proof that it is selling

The ad has run 14 days or more and is still active.
It has several versions: the brand relaunched the creative.
The brand runs a real number of ads, and is launching more than before.
There is a real shop behind it, ideally with meaningful traffic.

Crossendor rates every ad on these signals and shows the reason.

2. Demand: do people search for it?

Ads can create demand, but products with rising searches are easier. Check Google Trends for direction and keyword tools for monthly volume, in each market's language.

3. Competition: how crowded is it?

How many advertisers run the product in your market?
Who sells it on Amazon and Google Shopping, and at what price?
Is the leader the product's maker? Competing with the original brand is harder.

Check how many advertisers already run a product, per market.

4. The market: where would you be first?

A product crowded in the US can be open in Poland, Italy or Brazil. Check each market in its own language before you decide it is saturated.

Crossendor checks up to seven countries for the same product and gives each a verdict.

5. The numbers: can it make money?

Price at least three times your landed cost (product plus shipping).
Know your break-even ROAS before you spend.
Test several creatives and angles before you judge the product.

Work out your break-even ROAS and cost per purchase.

Questions

What makes a product a winning product?

It sells profitably through ads. Publicly, that shows as ads that keep running for weeks, get relaunched, come from a brand with a real shop, and sit in a niche people search for.

Where can I find winning products for free?

The Meta Ad Library and TikTok's Creative Center, read with the checklist above. Crossendor's weekly top 10 and trending products pages are free too.

How many winning products should I test?

Few, properly. Three products with three to five creatives each tells you more than ten products with one creative each.
