If you’ve ever felt like your Shopify conversion data doesn’t tell the full story, you’re not wrong. iOS privacy updates, browser restrictions, and ad blockers have created a new reality where critical events go untracked, attribution becomes guesswork, and your ad spend underperforms.
Client side tracking alone cannot keep up. That’s why more Shopify brands are choosing server-side tracking for Shopify through Server Side Google Tag Manager, a powerful solution that captures the full customer journey with accuracy.
Why Client Side Tracking Isn’t Enough in 2025
Shopify’s default tracking setup relies on browser-based data collection. But in today’s privacy-first ecosystem, that’s a growing liability. Here’s why:
- iOS limits tracking by default through App Tracking Transparency
- Ad blockers prevent pixels like Facebook and GA4 from firing
- Cookies often expire fast, breaking attribution
- Cross-device and funnel tracking often fail, especially at checkout
The result? Missing or mislabeled traffic in reports. You see “Direct” traffic where there should be attributed conversions. You lose visibility into key events like Add to Cart, Start Checkout, and Purchase. Your media buying decisions become harder because the data is incomplete.
How Server Side GTM Fixes What Shopify Misses
Server-side GTM doesn’t rely on the browser to send data. Unlike browser-based tracking, server-side GTM runs on the cloud. This avoids blockers and improves cookie life.
With Conversios, you get:
- Reliable iOS tracking that captures conversions even from Safari
- Higher Event Match Quality for Facebook and Google Ads
- First-party cookies that last longer and improve attribution
- Tracks over 15 key ecommerce events like view item, add to cart, purchase, login, and sign-up

It’s not just about tracking more. It’s about capturing the right events with the accuracy your campaigns need.
What Changes with Server Side Tracking
Let’s make this real. Here’s a comparison of Shopify tracking before and after switching to server side GTM:
| Scenario | Before | After |
| Facebook Pixel on iOS | Often blocked | Captured through CAPI |
| Google Ads Attribution | Frequently incomplete | Accurate with server calls |
| Conversion Path | Fragmented | Fully visible |
| Event Match Quality | 40 to 60 percent | 80 to 95 percent |
| Cookie Lifespan | Short, often deleted | Extended to over 90 days |
| Performance Max Signals | Delayed or missing | Sent in real time |
This is not just a technical change. It is a real opportunity to recover lost revenue and improve decision making.
Boost Your Facebook and Google Ads Match Quality
Improving your Event Match Quality (EMQ) is one of the fastest ways to enhance the performance of your ads. When your customer data is clean, complete, and delivered server-side, platforms like Facebook and Google can match it more accurately, leading to higher conversions and better attribution.
With Conversios, you can:
- Automatically send hashed customer identifiers like email, phone, and location
- Fix attribution gaps on iOS and Safari devices
- Improve your EMQ score from under 50% to over 90%
- Increase ROAS by giving ad platforms better signal data
