GA4 Ecommerce Tracking Setup: The Complete Guide for UK Stores

Why GA4 Tracking Matters for Google Ads

If your GA4 tracking is broken, your Google Ads performance will suffer. Smart Bidding relies on conversion data. Bad data = bad bidding.

And with Universal Analytics gone, GA4 is now essential. Here's how to set it up right.

The Ecommerce Events You Need

GA4 uses event-based tracking. For ecommerce, you need:

Core events:

• view_item
• add_to_cart
• begin_checkout
• add_payment_info
• purchase

Recommended events:

• view_item_list
• select_item
• add_to_wishlist
• remove_from_cart

Setting Up GA4 for Shopify

The easiest method:

1. Go to Online Store > Preferences
2. Add your GA4 Measurement ID (G-XXXXXXX)
3. Enable enhanced ecommerce

This covers basic events. For advanced tracking, use Google Tag Manager.

Setting Up GA4 for WooCommerce

Options:

1. MonsterInsights plugin (free/paid): Easy setup, handles most events
2. GTM4WP plugin + Google Tag Manager: More control, more complex
3. Manual GTM implementation: Full control, requires developer

For most stores, MonsterInsights is sufficient.

Setting Up GA4 via Google Tag Manager

The professional approach:

1. Create GA4 Configuration tag
2. Create Data Layer for ecommerce events
3. Create tags for each event (purchase, add_to_cart, etc.)
4. Create triggers for each event
5. Test in Preview mode
6. Publish

Connecting GA4 to Google Ads

Critical step:

1. In Google Ads: Tools > Linked accounts > Google Analytics (GA4)
2. Link your property
3. Import conversions: Tools > Conversions > New conversion action > Import

Verifying Your Setup

Check everything works:

1. GA4 DebugView: Real-time event verification
2. Google Tag Assistant: Browser extension for testing
3. GA4 Realtime reports: See events firing live
4. Test transactions: Complete actual purchases

Common GA4 Ecommerce Issues

• Duplicate transactions: Tags firing twice
• Missing revenue: Data layer not passing value
• Currency issues: Not matching account currency
• Cross-domain problems: Tracking breaks between checkout

UK-Specific Considerations

• VAT handling: Include or exclude from reported revenue?
• Currency: Ensure GBP is set correctly
• Cookie consent: Comply with UK GDPR
