¿Qué campo se puede usar para filtrar a eventos de tráfico de las campañas de anuncios patrocinados relevantes?

The campaign field is the most direct and effective way to filter traffic events specifically from relevant sponsored ad campaigns in Amazon Marketing Cloud (AMC). This field directly corresponds to the campaigns you set up, allowing for precise targeting of the data you need to analyze. While supplysource might indicate where an ad was served (e.g., Amazon DSP, Amazon Ads), it's broader and doesn't directly filter by your specific campaign names. userid identifies individual users but doesn't filter by the ad campaign they interacted with.
