用Shopify Custom Events方式向GA4、GTM、FB Pixel传值（实例三）

微光更新于 2024-01-03 13:07:27首发于 2024-01-03 12:36:18技术392

比实例一和实例二多了GTM和FAXCEBOOK。

Shopify自定义像素代码用于将分析工具（如Google Analytics、Google Tag Manager和Facebook Pixel）集成到Shopify网站中。该代码为各种事件设置了事件监听器，并将相关数据发送到指定的分析工具。

该代码为各种事件（如collection_viewed、page_viewed、product_viewed、search_submitted、product_added_to_cart、checkout_started、payment_info_submitted和checkout_completed）设置了事件监听器。当发生这些事件时，代码使用在analyticsTools对象中定义的sendEvent()函数将相关数据发送到指定的分析工具。

部署操作：

  • 转到Shopify > 设置 > 客户事件 > 添加自定义像素。
  • 将代码复制并粘贴到您的Shopify主题中。
  • 您可以使用analytics.subscribe() API订阅这些事件。analyticsTools对象中的sendEvent()函数会根据适当的事件名称和数据进行调用。

要了解如何创建Google Tag Manager(谷歌代码管理器)自定义像素或自定义像素代码的更多信息，请参考以下链接：

您可以通过修改analyticsTools对象中的属性来配置分析工具。例如，您可以通过将enabled属性设置为true或false来启用或禁用工具。您还可以更改分析工具的ID，以及启用/禁用调试模式。
