About Upstack Data

Train your ad platforms to find more customers. Upstack Data is the #1 Most Reliable Ad Tracking Software For Shopify. For Shopify brands running Meta, Google & TikTok ads, we provide server-side tracking that enriches every click — so your ad platforms optimize for buyers, not browsers. Most tools track anonymous actions. We resolve the identity of your visitors across browsers, devices, and sessions, then make sure Meta, Google, and Klaviyo get that information in a form they can act on. The result: lower CAC, better attribution, and more revenue recovered from abandonment flows. We've helped Shopify brands drive 7 & 8-figure growth through advanced visitor tracking and identity resolution — generating millions in recovered revenue.
