Ad arbitrage: sell a winning product where nobody sells it yet
5 min read · updated 5 November 2026
Why it works
- The proof is done: the product already sells through ads in another market.
- Less competition: fewer advertisers, cheaper attention.
- The creative is tested: the angle that works in one market often works in the next, translated and localised.
How to check another country
- 1
Start from a winner. An ad that has run for weeks, with versions and a real shop behind it.
- 2
Search in the local language. Use the words local sellers use, not a literal translation. "Insoles" is "Einlegesohlen" or "Einlagen" in German.
- 3
Look past the brand. The same product often runs under a different brand, photo and language. Match the product, not the ad.
- 4
Check the shelf. Who sells it on Amazon and Google Shopping there, and at what price.
- 5
Decide. Open: nobody runs it. Contested: someone does, but there is room. Crowded: skip it.

- The maker itself may already be there in English: you would compete with the original.
- Local rules, delivery times and returns differ by country.
- Localise the creative: language, currency, sizes and the problem as locals name it.
Questions
What is ad arbitrage in ecommerce?
Taking a product that already sells through ads in one market and launching it in a market where nobody advertises it yet.
Which markets are easiest to start in?
It depends on the product. Markets with large ecommerce spend and fewer advertisers per niche, such as Germany, France, Italy, Spain or Poland, often open up after the US and UK.
How does Crossendor know it is the same product?
Visual AI compares the ad creatives by what is in them, so the match is the physical product even when the brand, language or photo changes.
