Sarah would like to enable a custom parameter to be sent to SAS for every impression event. The information received is available in cookie-level insights and RDF reports. Which setting would she use to accomplish this?

The Publisher Custom Parameter allows you to pass custom, cookie-level data from your ad server to SAS (Sizmek Ad Suite) for every impression. This data is then available in cookie-level insights and RDF (Raw Data Feed) reports, making it ideal for detailed analysis. Click Tracking Token and Impression Tracking Token are used for tracking specific events (clicks and impressions, respectively) and are not designed for passing custom, cookie-level parameters for reporting. Line ID is an internal identifier for an ad campaign line item and does not serve the purpose of passing custom data.
