This script is a core component of AdRoll's advertising and marketing platform. It is deployed on websites to collect user browsing behavior, such as page views, product interactions, and conversion events. The primary purpose of this data collection is to build audience segments for targeted advertising and retargeting efforts across various ad networks and platforms. The script operates client-side, executing within the user's browser to capture real-time interactions. It typically sends this behavioral data back to AdRoll's servers for processing and analysis. To maintain user identity across different sessions and websites, it often leverages cookies, enabling consistent personalized ad delivery and accurate attribution for marketing campaigns.
