A Server Data Layer is a structured data object that exists on the server instead of the browser. It collects user actions, context, and metadata in a controlled environment before forwarding data to analytics or advertising platforms. This approach reduces reliance on browser scripts, improves data consistency, and limits exposure of sensitive information. A server data layer is especially valuable for privacy compliance and advanced transformations.
