How Proven Skincare Fixed Headless Tracking with Littledata
Introduction
Proven Skincare, a data-driven skincare brand, recently launched a headless Shopify storefront using Next.js to deliver a more personalized and performant ecommerce experience, alongside their existing Liquid storefront.
Maintaining precise analytics and reliable attribution across both environments was non-negotiable. With Segment central to their data stack, Proven Skincare needed tracking that worked without introducing technical debt or custom infrastructure.
Challenge
Migrating to a headless architecture typically introduces significant tracking complexity:
- Session and user identifiers like Segment’s Anonymous ID and Meta Pixel ID are not shared between a custom storefront and the Shopify checkout
- This leads to broken user journeys, incomplete attribution, and inaccurate data in analytics and ad platforms
- Standard Shopify tracking apps don’t support headless storefronts, and patching with custom scripts adds long-term maintenance overhead
Solution
Proven Skincare deployed Littledata’s Advanced Tracking Script - a server-side, no-code tracking solution designed for headless Shopify.
Within 5 minutes, they had:
- Server-side tracking is deployed across Next.js storefront and Shopify checkout
- User identifiers for the key marketing platforms (Segment, Meta, GA4, Google Ads, TikTok, Pinterest) are automatically captured and linked
- A robust connection between each checkout and its originating session + campaign source
No custom code. No client-side complexity. Full visibility restored.
Tech Stack Compatibility
| Layer | Tools/Frameworks |
|---|---|
| Frontend | Next.js (via Storefront API) |
| Checkout | Shopify checkout (same root domain) |
| Analytics & Ads | Segment, Meta, Google Analytics (GA4), Google Ads |
| Tracking Layer | Littledata Advanced Tracking Script |
Outcome
- Full event data parity between Liquid and headless stores
- Every checkout event is accurately attributed to the correct user and campaign
- Reliable, unified analytics flowing into Segment and downstream tools
- Zero engineering effort required
With Littledata in place, Proven Skincare operates a modern, flexible tech stack with complete marketing and analytics fidelity.
Summary
Proven Skincare successfully modernized its ecommerce stack without sacrificing data integrity. With Littledata’s headless tracking, they gained:
- End-to-end visibility across fragmented storefronts
- Clean, consistent attribution into Segment and ad platforms
- A scalable setup that doesn’t require ongoing developer involvement
For CTOs building composable commerce stacks, Littledata is a low-effort, high-trust way to keep tracking airtight, even in headless environments.
