What is North Star Metric?
North Star Metric (NSM) is a server-side attribution platform built for Shopify stores. It tracks every visitor, click, and conversion using first-party data — bypassing the limitations of client-side tracking, iOS 14+ restrictions, and ad blockers. Instead of relying on browser cookies that disappear, NSM creates a privacy-safe device fingerprint from stable browser signals (WebGL, fonts, screen properties, etc.). This fingerprint persists across sessions and incognito mode, giving you accurate attribution even when cookies are blocked.Who is it for?
NSM is designed for:- DTC brands spending $1,000+/month on paid ads (Meta, Google, TikTok)
- Shopify merchants who’ve seen their reported ROAS drop after iOS 14
- Agencies managing multiple Shopify stores that need accurate cross-store reporting
- Any store that wants to know which ads actually drive revenue, not just platform-reported numbers
