Find the winning products your competitors are scaling

WinWatcher follows Shopify stores for you and tells you the moment a product starts selling. Test the next winner while it is still early, not when every “top 10 winners” list has it.

From their best seller to your scaled winner.

Five tools, one goal

Find your next winning product before it is everywhere.

When a store starts scaling a product, it climbs their best-seller list, their ads go up and their emails push it. WinWatcher sees all of it, so you can test the winner while it is still early.

Chrome extension · Store sidebar

Open any Shopify store. See what sells.

One click on the WinWatcher icon and the store opens up: its best sellers in their real order, the place of the product you look at, its ads, visits, reviews, theme and apps. Follow it in one click and WinWatcher keeps an eye on it for you.

What the sidebar shows you

  • Bestseller positionThe place of the product you look at in the store’s own best-selling order: #4 of 1,752 means it is one of their winners.
  • Active Meta adsHow many ads the store runs right now, and the trend. A jump means they are scaling something.
  • New since your last visitThe products added since you were here, and which of them already sell.
  • Visits and reviewsMonthly visitors from Similarweb and the Trustpilot score, without leaving the store.
  • Theme, apps and checkoutThe Shopify theme, the apps and pixels they run, and how they take payments.
  • MarketThe country they sell to, from shipping countries, domain, currency and couriers.
Risers & Scalers

Spot the winning product while it climbs.

A product that jumps hundreds of places in a few days is a store spending money on it. Risers puts those jumps on top after every scan; Scalers shows what climbed most between any two days, with a Winner score and the reasons.

See every change on their store.

WinWatcher screenshots the pages you pick every week and puts them side by side. New banner, new price, a button in a new colour, a sale that started: it is marked, in its own colour, with what changed.
