# GA4 web tracker

## Purpose / when to use

Use **GA4 (Web) Tracker** to send ecommerce events to Google Analytics 4 for reporting and attribution.

  

If you don’t have a GA4 account or GA4 property yet, create them first:

## Requirements

-   A **GTM Web container** connected in Multifeeds
    
-   **GA4 Measurement ID** (format `G-XXXXXXXXXX` )
    

  

## Getting the Measurement ID

A Google Analytics Measurement ID is a unique code that connects your website to Google Analytics 4.

  

You can find your Measurement ID here:

## Testing + troubleshooting

### Testing

**Option A — Realtime report (recommended, easiest)**

1.  In Google Analytics, go to **Reports → Realtime overview**
    
2.  Open your Shopify store in another browser/tab
    
3.  Navigate product pages, cart, and checkout steps
    
4.  Confirm realtime users/events appear as you browse
    

  

Realtime report:

**Option B — Debugging tools (advanced)**

-   Use **GTM Preview** to confirm tags fire for selected events.
    
-   Use **GA4 DebugView** if you have debug mode enabled (availability may vary by setup).
    

  

### Troubleshooting

-   **Invalid Measurement ID:** must match `G-`  + 10 uppercase letters/numbers.
    
-   **Missing events:** verify selected events and your consent/market filters.
    
-   **No realtime data:** allow a few minutes, confirm the correct property/data stream, and verify the tracker is **Enabled**.
