The Google Language Switcher for OpenCart can send events to Google Analytics when visitors interact with the language popup.
Tracking these events helps you understand:
- which languages visitors prefer
- how many users switch language
- which markets show interest in your store
- whether multilingual support improves engagement
This article explains how to verify and analyze language events in Google Analytics 4 (GA4).
Events Sent by the Extension
When enabled, the extension sends the following events using gtag:
Event Names
| Event Name | Description |
|---|---|
| open_translate_popup | triggered when visitor opens language popup |
| translate_language_selected | triggered when visitor selects a language |
These events help measure how often visitors interact with the language switcher.
