When customers migrate from Universal Analytics to Google Analytics 4, they have the option to utilize a feature known as connected site tags. This feature enables them to reuse their existing analytics.js website tag. Recently, enhancements have been introduced to further improve the tag reuse process. These enhancements include the ability to transmit enhanced ecommerce data, custom dimensions and metrics, and other customized tag data to GA4 properties. For more information on this feature, please refer to the Google Analytics Help Center.
