Why Your Attribution Data Doesn’t Match Across Platforms

Wondering why attribution reports don’t match in Shopify, GA4, or your ad accounts? Here’s what’s happening—and how Analyzify fixes it.

Shopify says the conversion came from Facebook. GA4 says it was direct. Google Ads claims credit for the same sale.

Sound familiar? You’re not alone. Attribution data rarely lines up across platforms—and that creates real problems for ecommerce teams trying to optimize ad spend and understand what’s working.

The Problem: Conflicting Attribution Data Across Platforms

When your attribution data tells a different story depending on where you look, it doesn’t just create confusion—it impacts your budget, campaign strategy, and trust in your own numbers.

You might see:

  • Higher conversions reported in Google Ads than in GA4
  • Facebook taking credit for conversions already counted elsewhere
  • A growing gap between what Shopify shows and what your ad platforms report

This isn’t a technical glitch—it’s the natural result of how each platform handles attribution.

Why Attribution Metrics Don’t Match Between Shopify, GA4, and Ad Platforms

Each platform has its own approach to tracking user behavior and assigning credit for conversions. Let’s break it down:

  • Shopify tracks events directly on your storefront and uses a last-touch model. It ties orders to the last known source and stores attribution data in the order record itself.
  • GA4 uses a data-driven attribution model, blending real and modeled data to estimate what drove the conversion. It’s session-based and heavily impacted by cookie availability.
  • Google Ads & Meta Ads rely on Click IDs (like GCLID or FBCID) stored in browser cookies. They also use their own attribution windows, which may stretch well beyond what Shopify tracks.

Now layer on top of that:

  • Cookie restrictions from Safari, Firefox, and iOS
  • Users switching devices or clearing their history
  • Ad blockers and tracking preferences

Suddenly, it’s no wonder one conversion appears under three different sources across your reports.

How Analyzify Helps You Align Attribution Across Platforms

Analyzify acts as your attribution backbone. Instead of relying on fragile cookies or modeled assumptions, we capture key attribution data at the cart level—when users add products to their cart.

This is a turning point in the user journey. By preserving UTM parameters, Google Click ID (GCLID), Facebook Click ID (FBCID), referrer, and other identifiers in Shopify at this exact moment, we lock in the real source of the visit—before cookie restrictions or device changes can erase it.

Why Your Attribution Data Doesn’t Match Across Platforms

That data is:

  • Stored securely in Shopify, not in browser cookies
  • Tied to the order, even if the user returns later or switches devices
  • Transmitted to platforms like Google Ads, Meta, and GA4 through our server-side infrastructure

By giving each platform the cleanest and most complete version of the user journey, you reduce attribution gaps—and regain control over how conversions are credited.
