The Shopify E-commerce Accelerator: Fix Your Attribution & Get Accurate ROAS

Are your ad platforms all claiming credit for the same sale? When Meta, Google Ads, and Klaviyo operate in silos, your total reported conversions often exceed actual sales, making true Return On Ad Spend (ROAS) a guessing game. This attribution chaos is amplified by iOS 14+ updates and browser privacy features, which block traditional tracking pixels, causing significant data loss and leading to misinformed budget decisions.

The Shopify E-commerce Accelerator implements a robust, server-side tracking system to create a single source of truth for your conversion data. This playbook uses Elevar to seamlessly capture every critical e-commerce event directly from your Shopify store—from 'Add to Cart' to 'Purchase'. This clean, complete data is sent to a secure Google Tag Manager Server container, which then reliably relays it to all your marketing destinations like Meta (via CAPI), Google Ads, and Klaviyo, bypassing browser-level tracking blockers.

Expected Outcomes

  • Dramatically improve the accuracy of conversion data sent to Meta, Google Ads, and Klaviyo.
  • Gain a clear and reliable understanding of your true Return on Ad Spend (ROAS) across all channels.
  • Mitigate data loss from iOS 14+ and other browser privacy restrictions by leveraging server-side tracking.
  • Eliminate data silos by creating a single, unified source of truth for your e-commerce analytics.
  • Make smarter, data-driven budget allocation decisions to scale your most profitable channels.

Integration Logic

  • Elevar Shopify Data Layer Bridge

    This integration creates a robust server-to-server data pipeline. Elevar's data layer, installed on a Shopify store, captures detailed e-commerce events (e.g., Product Viewed, Add to Cart, Purchase). These events are sent from the client's browser directly to a Google Tag Manager (GTM) Server container. Inside the GTM Server container, a specific Klaviyo tag is configured to listen for these incoming events. When an event is received, the GTM Server container reformats the data and forwards it to Klaviyo's API. This server-side approach ensures higher data fidelity by avoiding ad blockers and browser privacy features that can disrupt traditional client-side tracking.
