Description
A comprehensive overview of this resource
This script is part of Xandr's (formerly AppNexus) advertising infrastructure. It's primarily used for "user syncing," a critical process in programmatic advertising. When loaded, it typically sends a request to Xandr's servers to establish or confirm a user's identity. This process involves exchanging identifiers (IDs) with other ad tech partners (e.g., Demand-Side Platforms, Supply-Side Platforms, Data Management Platforms) to create a unified view of a user across different websites and devices. This enables advertisers to recognize users and serve relevant ads, perform retargeting, and build audience segments. It operates by dropping or reading cookies to maintain a persistent user ID.
