How to Setup Google Analytics with BigCommerce (2026 Guide)

Overview

Connecting Google Analytics 4 (GA4) to BigCommerce provides detailed insights into how customers find your store, navigate your site, and complete purchases. GA4's ecommerce tracking captures the full shopping funnel: product views, add-to-cart events, checkout steps, and purchases with revenue data. This data enables informed decisions about marketing spend, product merchandising, site optimization, and customer acquisition strategy.

BigCommerce supports GA4 integration natively through its built-in analytics settings. The setup involves creating a GA4 property, adding your Measurement ID to BigCommerce, and configuring enhanced ecommerce tracking. BigCommerce automatically sends standard ecommerce events to GA4 without requiring custom code or Google Tag Manager, though GTM is available for advanced tracking needs.

Prerequisites

• A BigCommerce store on any plan
• A Google Analytics 4 property (not Universal Analytics, which is no longer active)
• A Google account with admin access to the GA4 property
• BigCommerce store owner or admin access

Step-by-Step Setup

Step 1: Create a GA4 property

If you do not already have a GA4 property, go to analytics.google.com. Click Admin (gear icon) in the bottom left. Click Create Property. Enter your store name, select your time zone and currency (match your BigCommerce store currency), and click Next. Select your industry category and business size. Choose Examine user behavior as a business objective. Click Create.

Step 2: Get your Measurement ID

In your GA4 property, go to Admin > Data Streams. Click Add stream > Web. Enter your BigCommerce store URL and a stream name. Click Create stream. Copy the Measurement ID (starts with "G-").

Step 3: Add GA4 to BigCommerce

In your BigCommerce admin, go to Settings > Analytics > Google Analytics. Enable Google Analytics by toggling it on. Paste your GA4 Measurement ID into the Google Analytics 4 Property ID field. Ensure Enhanced Ecommerce is toggled on. Click Save.

Step 4: Verify tracking is active

Visit your BigCommerce store in a browser. In GA4, go to Reports > Realtime. You should see your visit appear within a few seconds. Browse some products, add an item to cart, and verify that events like view_item and add_to_cart appear in the Realtime report.

Step 5: Configure ecommerce reporting

In GA4, navigate to Reports > Monetization > Ecommerce purchases. This report will populate with data as customers make purchases. You can also access the Purchase journey report under Reports > Monetization to see the full shopping funnel from session start through purchase.

Step 6: Set up conversion tracking

In GA4, go to Admin > Events. Find the purchase event and toggle it as a conversion (or under Admin > Conversions, add purchase as a conversion event). This ensures purchase data appears in conversion reports and can be used for Google Ads optimization.

Step 7: Link Google Ads (optional)

If you run Google Ads, link your GA4 property to your Google Ads account under Admin > Google Ads Links. Click Link, select your Google Ads account, enable personalized advertising, and click Submit. This enables importing GA4 conversions into Google Ads for campaign optimization and creates audiences for remarketing.

Configuration Options

GA4 automatically tracks standard ecommerce events when Enhanced Ecommerce is enabled in BigCommerce. These include view_item, add_to_cart, remove_from_cart, begin_checkout, add_shipping_info, add_payment_info, and purchase. To track additional custom events or modify the default implementation, use Google Tag Manager (add your GTM container ID in BigCommerce under Settings > Analytics > Google Tag Manager). Configure data retention under Admin > Data Settings > Data Retention (default is 2 months; extend to 14 months for longer-term analysis).

What Syncs

Best Practices

• Extend data retention to 14 months under Admin settings to enable year-over-year comparisons
• Create custom explorations in GA4 for funnel analysis specific to your checkout flow
• Set up audiences for remarketing: cart abandoners, past purchasers, and high-value customers
• Use UTM parameters on all marketing links to accurately attribute traffic and revenue to campaigns
• Enable Google Signals under Admin > Data Settings for cross-device tracking and demographic data
• Create custom channel groupings if your marketing channels do not fit GA4's default categories

Common Issues and Fixes

No ecommerce data in reports

Ecommerce reports require at least one purchase event with revenue data. Test a complete purchase on your store (use a test coupon for 100% discount if needed) and verify the purchase event appears in Realtime with revenue data. If page views track but ecommerce events do not, ensure Enhanced Ecommerce is enabled in BigCommerce settings.

Revenue discrepancy between GA4 and BigCommerce

GA4 may show different revenue than BigCommerce due to several factors: GA4 records revenue at the time of the JavaScript event (which may not fire if the customer closes the browser during checkout redirect), excludes orders placed via phone or manually in BigCommerce admin, and may double-count if the thank-you page is refreshed. Use BigCommerce as the source of truth for revenue and GA4 for traffic and behavior analysis.

Self-referral traffic from payment processor

If your checkout redirects to a payment processor (PayPal, payment gateway hosted page), returning traffic may show the payment domain as a referral source. Add the payment processor's domain to GA4's referral exclusion list under Admin > Data Streams > [your stream] > Configure Tag Settings > List unwanted referrals.

Advanced Configuration

For advanced tracking, implement Google Tag Manager alongside the native GA4 integration. GTM allows you to track custom events like newsletter signups, product filter usage, promotional banner clicks, and video interactions. Use GA4's BigQuery export (available on all properties) to run SQL queries against your raw event data for custom analysis that GA4's reporting interface cannot handle. Set up Looker Studio dashboards connected to GA4 for custom ecommerce reporting that combines GA4 data with data from other sources.
