Available keys include Resettable Device IDs (RDIDs), Custom Floodlight variables, and LiveRamp RampIDs. The choice of key depends on how your data is structured, not the specific use case. The process involves uploading data to BigQuery, granting Ads Data Hub service account permissions, and using a join key to merge the two datasets. This process is beneficial for improved advertising analysis, audience building, and attribution.\n"]]
