This script is the core tracking tag for Bloomreach Engagement, a powerful customer data platform (CDP) that was formerly known as Zaius. It is designed to be embedded on a website to capture a comprehensive range of visitor interactions and behavioral data. This includes page views, product views, add-to-carts, purchases, search queries, form submissions, and other custom events defined by the website owner. The script works by observing user activity in the browser, packaging this information, and transmitting it to Bloomreach's backend servers. This data is then used to build rich, unified customer profiles, segment audiences, and fuel personalized marketing campaigns across various channels, such as email, SMS, push notifications, and on-site experiences. It typically utilizes cookies to identify unique users across sessions and devices, allowing for a continuous understanding of customer journeys. By centralizing customer data, the script enables businesses to create highly relevant and timely communications, optimize user experiences, and drive conversions based on individual preferences and past behaviors.
