SellWinners: Shopify store and ad research

See any store's traffic, sales, ads, apps and best sellers beside the page, and save ads from Meta, TikTok and Instagram.

Research any online store without leaving the page. SellWinners puts a store's key figures beside the page you are on: monthly visits and their countries, estimated sales and units a day, best sellers, theme, Shopify apps and pixels, similar shops, and the store's latest Meta, Google and TikTok ads and emails. Built for e-commerce sellers, dropshippers, media buyers and agencies. What you can do: - Open a store's figures in the side panel or a floating panel, on any Shopify store and on stores built with WooCommerce, Wix, Squarespace, BigCommerce and more. - See the ads that send traffic to the page you are on. - On a product page: that product's sales estimate, reviews and ads, plus a margin calculator with the price filled in. - Right-click any image to find similar products, with the results beside the page. - In the Meta Ad Library: save ads to your boards, reveal spend, sort by spend and download media. - On TikTok: see plays, likes, comments, saves and shares, sort, autoscroll and save. - On Instagram: save posts to your boards. - Write ad hooks from the ad on screen. - Compare a store with a similar one, side by side. - Export a store's product catalog as CSV, and copy a one-page store brief. - Tools: download media, view the page as a phone or tablet, pick colours, detect fonts. - Light, dark and six accent colours, in nine languages, following your SellWinners account. Light on every page: the extension only detects whether a page is a store. Nothing is sent while you browse; figures load when you open the panel. A SellWinners account is needed for store figures (a Free plan is available). Tools and store detection work on every plan.
