The D2C Growth Stack: Your Single Source of Truth for Accurate ROAS

Your ad platforms are all claiming credit for the same sale. Meta, Google, and TikTok report in silos, inflating conversion numbers and making it impossible to know your true Return on Ad Spend (ROAS). Compounded by significant data loss from iOS 14+ privacy updates, you're left guessing where to allocate your budget, wasting money on underperforming channels.

This playbook details 'The D2C Growth Stack,' a powerful, low-effort solution for Shopify-based brands. By centralizing your marketing data in Triple Whale, you'll get a unified view of your entire customer journey. This stack pulls data directly from Shopify, your ad platforms (Meta, Google, TikTok), and Klaviyo, bypassing the siloed, inaccurate reporting of individual platforms. The result is a single, reliable source of truth for attribution and ROAS, built for seamless integration with minimal technical setup.

Integration Logic

  • Triple Whale E-commerce Data Unifier

    This integration centralizes data within Triple Whale. First, the Triple Whale pixel is installed on a Shopify store to capture real-time user events (page views, add to carts, checkouts, purchases). Simultaneously, an API connection pulls historical order, product, and customer data from Shopify. Second, Triple Whale connects to the Klaviyo API to ingest all email and SMS campaign data, including sends, opens, clicks, and associated subscriber information. Triple Whale then merges these two data streams, matching user interactions from Klaviyo campaigns to purchase events on Shopify using customer identifiers. This allows for advanced, multi-touch attribution, revealing the true influence of Klaviyo marketing efforts on sales beyond simple last-click metrics.
