GA4 vs. Universal Analytics for eCommerce: Key Differences
Before diving into implementation, it's important to understand how GA4 differs from Universal Analytics for ecommerce tracking:
Event-Based vs. Session-Based Model
Universal Analytics: Focused on sessions and pageviews, with ecommerce activities tracked as separate hits within a session.
GA4: Built around an event-based model where everything is an event. This provides more flexibility but requires a different implementation approach.
Reporting Structure Changes
Universal Analytics: Featured dedicated ecommerce reports like "Shopping Behavior" and "Checkout Behavior."
GA4: Uses a more customizable approach with "Exploration" reports and the "Monetization" section, requiring more setup but offering greater flexibility.

Timeline for Migration
Universal Analytics stopped processing new data on July 1, 2023. If you haven't migrated to GA4 yet, you're already missing historical data. The sooner you implement GA4 ecommerce tracking, the more historical data you'll have for future analysis.
Before You Begin: GA4 eCommerce Setup Prerequisites
Before implementing any tracking solution, ensure you have these prerequisites in place:
1. Create a GA4 Account
1. If you haven't already, create a new GA4 account:
2. Log in to your Google Analytics account and click "Admin" in the bottom left corner:
3. Click on Create button at the top and choose Account.
4. Follow the GA4 setup wizard. Start by adding your Account name, such as “Heatmap Blog”. Select Google products & services.
Note: We don't recommend setting up a separate GA4 account solely for your blog; this is for demonstration purposes only. The blog on your site should be automatically covered by your main GA4 account.
5. Add the name of your property such as: Heatmap Blog - GA4 and select your time zone.
6. Describe your business by choosing your Industry Category and Business Size:
7. Choose the first 4 business objectives and click on "Create".
8. Check both Google terms and click on "I Accept".
9. From the data collection section choose "Web".
10. Set up the data stream by adding your domain and stream name.
11. When the setup is done, copy the Measurement ID. You will need it for later.
2. Required Access and Permissions
Ensure you have:
Admin access to your Shopify store
Admin access to your Google Analytics account
Google Tag Manager account (for GTM implementation method)
Ability to edit your Shopify theme code (for direct implementation methods)
3. Information Checklist
Before proceeding, gather:
Your GA4 Measurement ID
Your Shopify store URL
List of key events you want to track
Understanding of your Shopify theme structure
Method 1: Shopify's Google & YouTube Channel App
The simplest implementation method uses Shopify's native Google & YouTube Channel app, which requires minimal technical knowledge.
Step-by-Step Installation Process
Install the app:
Go to your Shopify admin
Navigate to Apps > Visit Shopify App Store
Search for "Google & YouTube Channel"
Click "Add app" and install
Connect your Google account:
Once installed, open the app
Click "Connect" to link your Google account
Follow the authentication prompts
Select your GA4 property:
Choose the GA4 property you created earlier
If you don't see your property, ensure you have admin access to it
Follow the prompts to complete the connection
Verify installation:
In your GA4 account, go to Reports > Realtime
Visit your Shopify store in another tab
You should see your activity appear in the realtime report
Events Tracked Automatically
The Google & YouTube Channel app automatically tracks these ecommerce events:
page_view: When a user views any page
view_item: When a user views a product
add_to_cart: When a product is added to cart
begin_checkout: When checkout is initiated
purchase: When an order is completed
Pros and Cons of This Approach
Pros
Cons
Maximum flexibility and customization
More complex setup
Ability to track custom events
Requires technical knowledge
More control over data quality
Can impact page load speed if not optimized
Can be updated without changing theme code
Requires ongoing maintenance
P.S., Unlike GA4's complex GTM setup that can take 20-40 hours of developer time, heatmapAI works out of the box with zero custom code, providing immediate visual insights into how users interact with your Shopify store!
Method 3: Direct GTAG Implementation
For those who want to avoid GTM but still need more control than the Shopify app offers, direct GTAG implementation is a middle-ground solution.
Adding GA4 Global Site Tag to theme.liquid
In your GA4 property, go to Admin > Data Streams > Your Web Stream
Click on "Configure tag settings" > Installation instructions > "Install manually"
Copy the provided script (starts with <!-- Google tag (gtag.js) -->)
In your Shopify admin:
Go to Online Store > Themes
Click "Actions" > "Edit code" on your active theme
Open the theme.liquid file
Paste the script just before the closing </head> tag
Click "Save"
Setting Up Purchase Tracking on Order Status Page
In your Shopify admin, go to Settings > Checkout
Scroll down to "Order status page"
In the "Additional scripts" box, add the following code (replace G-XXXXXXXX with your Measurement ID):
Optimization Focus: Target the step with the highest drop-off rate for immediate improvements.
Creating Custom Reports
For specialized analyses:
Go to Explore > Create a new exploration
Select the appropriate technique (funnel, path, segment overlap, etc.)
Add dimensions and metrics relevant to your analysis
Save and share with your team
Example Custom Report: "Marketing Channel Effectiveness" comparing traffic sources by conversion rate and average order value.
Advanced GA4 Configuration for Shopify
Take your GA4 implementation to the next level with these advanced configurations:
Enhanced Measurement Settings
Fine-tune what GA4 tracks automatically:
In GA4, go to Admin > Data Streams > Your Web Stream
Under "Enhanced measurement," toggle specific events on/off:
Outbound clicks
Site search
Video engagement
File downloads
Scrolls
Best Practice: Enable site search tracking to understand what products customers are looking for.
Custom Dimensions for Shopify-Specific Data
Create custom dimensions to enrich your analytics:
In GA4, go to Configure > Custom definitions
Click "Create custom dimensions"
Add dimensions like:
Product collection
Product vendor
Customer lifetime value tier
Discount code used
Shipping method
Implementation Note: You'll need to modify your event code to include these custom dimensions.
Audience Creation for Remarketing
Build audiences for targeted marketing:
In GA4, go to Configure > Audiences
Click "New audience"
Create segments like:
Cart abandoners (began checkout but didn't purchase)
High-value customers (purchase value > $X)
Product category enthusiasts (viewed multiple items in a category)
Discount seekers (only purchase with promo codes)
Integration Tip: Connect your GA4 property to Google Ads for seamless audience targeting.
BigQuery Export Options
For advanced analysis of raw data:
In GA4, go to Admin > BigQuery Linking
Follow the steps to link your BigQuery project
Configure daily exports of your GA4 data
Analysis Possibilities:
Custom attribution models
Detailed path analysis
Predictive customer lifetime value
Product affinity analysis
Cohort retention analysis
Connecting with Google Ads
For closed-loop marketing analytics:
In GA4, go to Admin > Google Ads Linking
Select the Google Ads account to link
Choose the data you want to share
Enable auto-tagging in Google Ads
Optimization Strategy: Use GA4 conversion data to optimize Google Ads bidding for ROAS rather than just clicks or basic conversions.
Best Practices for GA4 eCommerce Analytics
Follow these best practices to get the most value from your GA4 implementation:
Regular Verification of Data Accuracy
Establish a routine data quality check:
Weekly checks:
Compare order counts between GA4 and Shopify
Verify revenue numbers match (accounting for attribution differences)
Check for unexpected traffic spikes or drops
Monthly audits:
Review event parameter consistency
Check for missing data in key reports
Validate conversion tracking across devices
Tool Tip: Set up GA4 anomaly detection alerts for key metrics to catch issues early.
Creating Custom Dashboards
Build dashboards for different stakeholders:
For executives:
High-level KPIs: Revenue, conversion rate, AOV
Month-over-month and year-over-year comparisons
Marketing channel effectiveness summary
For marketing teams:
Campaign performance metrics
Traffic source analysis
Landing page conversion rates
For merchandising teams:
Product performance data
Collection effectiveness
Inventory insights
Implementation Approach: Use GA4's built-in dashboard customization or export to Google Looker Studio for more advanced visualizations.
Setting Up Automated Reports
Save time with automated reporting:
In GA4, go to Reports > Library
Create a custom report
Click "Share" and schedule email delivery
Set frequency (daily, weekly, monthly)
Best Practice: Include annotations for major events (sales, marketing campaigns, website changes) to provide context for metric changes.
Analyzing Customer Journey
Gain deeper insights into the purchase path:
Use path exploration reports to identify common routes to purchase
Analyze time to purchase by channel and device
Identify key touchpoints that influence conversion
Map content engagement to purchase behavior
Advanced Technique: Create segments based on journey length (quick converters vs. research-heavy buyers) to tailor marketing strategies.
A/B Testing with GA4
Leverage GA4 for testing and optimization:
Create custom dimensions to track test variants
Set up conversion events for test goals
Use exploration reports to compare variant performance
Integrate with Google Optimize for visual testing
Testing Framework: Start with high-traffic pages and focus on single variables to get statistically significant results faster.
Pro Tip: Enhance your analysis with heatmapAI's comparison mode, which allows you to compare different customer segments like purchasers vs. non-purchasers or high vs. low AOV customers to identify what drives revenue.
The Limitations of GA4 for Shopify Stores
While GA4 offers powerful capabilities, it's important to understand its limitations for Shopify stores:
Revenue Inflation Issues
GA4 typically reports higher revenue than what you actually collect because:
It tracks gross sales before discounts are applied
It doesn't account for refunds unless specifically configured
It may double-count revenue if purchase events fire multiple times
This can lead to misleading metrics when making business decisions based on GA4 ecommerce data alone.
Complex Setup Requirements
Implementing comprehensive GA4 tracking requires:
Technical knowledge of JavaScript and data structures
Understanding of GTM and event configuration
Familiarity with Shopify's theme architecture
Ongoing maintenance as both platforms evolve
For many merchants, this technical barrier results in incomplete or incorrect implementation.
Delayed Reporting
GA4's standard reports have significant processing delays:
24-48 hours for standard report data
Limited real-time data (only shows the last 30 minutes)
Exploration reports can take even longer to process
This delay makes it difficult to respond quickly to issues or opportunities.
Privacy Concerns and Cookie Limitations
GA4 faces growing challenges with:
Browser-based cookie blocking (Safari, Firefox)
Ad blockers preventing script execution
GDPR and CCPA compliance requirements
Apple's App Tracking Transparency framework
These factors can lead to incomplete data collection and underreporting of user behavior.

The Gap in GA4: What's Happening vs. Why It's Happening
While GA4 provides valuable data on what is happening on your Shopify store, it falls short in explaining why customers behave the way they do. This distinction is crucial for making effective optimization decisions.
The Limitations of Traditional Analytics
GA4 can tell you:
How many visitors viewed a product
How many added it to cart
Your overall conversion rate
Which pages have high bounce rates
But it cannot tell you:
Why visitors abandoned their carts
Which specific elements on a page drive conversions
If users are experiencing frustration with your interface
Which product images or descriptions are most compelling
How far down the page users scroll before making decisions
This creates a significant blind spot in your optimization efforts. You know there's a problem, but you're left guessing about the cause.
Bridging the Gap with Visual Analytics
To truly understand customer behavior, you need visual analytics tools that reveal how users actually interact with your store:
Revenue-Based Heatmaps
Traditional heatmaps show where users click. heatmapAI's revenue-based heatmaps go further by showing which clicks actually generate money.
Real-world application: Obvi, an 8-figure health and wellness brand, used revenue-based heatmaps to analyze their main paid landing page. heatmapAI's CRO engine revealed that their primary CTA button was positioned below the average fold height (682px) on mobile devices, causing potential customers to miss it. After repositioning the button above the fold, they added $2.5 million in revenue to their sales!
Scrollmaps reveal how far users scroll down your pages and—more importantly—where they stop.
Why it matters: If users aren't scrolling far enough to see key product features or your "Add to Cart" button, your conversion rate suffers. GA4 might show a high bounce rate, but heatmapAI's scrollmap shows exactly where you're losing customer attention.
Rage Click Detection
Rage clicks occur when users repeatedly click on an element that isn't responding or isn't clickable, indicating frustration.
What GA4 misses: GA4 might show that users are leaving a page, but rage click detection reveals they're trying to interact with elements that aren't working as expected.
Session Recordings
Watch real users navigate your store to identify usability issues, hesitations, and conversion barriers.
Beyond the numbers: While GA4 shows a user visited five pages before leaving, session recordings show they struggled to find the size chart, hesitated on the shipping information, and abandoned when they couldn't easily find the return policy.
AI-Powered Recommendations
Unlike traditional analytics that only present data, AI-powered tools analyze patterns and provide actionable recommendations.
Proactive optimization: heatmap's CRO AI engine analyzes user behavior patterns and automatically generates specific recommendations to increase conversion rates and revenue per session.
Real results: JellyBee, a supplement brand, used heatmapAI to optimize their listicle landing page. The CRO engine recommended adding a human element by featuring a middle-aged woman (their target demographic) holding the product in their hero image. This simple change increased conversion rates by 24.7% and boosted ROAS by 31%—generating over $650,000 in additional annual revenue.
"Users are rage-clicking on non-functional elements and leaving"
"Is my page too long?"
"Average time on page is 45 seconds"
"80% of users never scroll past the midpoint where your key features are"
"Why aren't users converting?"
"Conversion rate dropped by 12%"
"Users are confused by your new checkout process and abandoning at the payment step"
"How effective is my CTA?"
"Button has a 2% click rate"
"Button generates $4.50 revenue per session when clicked"
The Power of Combined Insights
The most effective approach combines GA4's quantitative data with visual analytics' qualitative insights:
Use GA4 to identify what is happening and where issues exist
Use visual analytics to understand why it's happening and how to fix it
Implement changes based on this complete picture
Measure the impact in both tools to validate improvements
Beyond Standard Tracking: The Power of "What" + "Why"
Setting up GA4 ecommerce tracking for your Shopify store is an important first step in understanding your business performance. By choosing the right implementation method—whether it's the simple Google & YouTube Channel app or the flexible Google Tag Manager approach—you'll gain valuable data about what's happening on your store.
But knowing what's happening is only half the battle. To truly optimize your Shopify store and drive meaningful revenue growth, you need to understand why customers behave the way they do.
While GA4 provides the foundation for understanding your store's performance, heatmapAI adds the critical layer of "why" with real-time, revenue-attributed insights. Brands like JellyBee and Obvi have seen dramatic improvements in conversion rates and revenue per session by acting on these insights. Why not see what heatmapAI can reveal about your Shopify store?
