Since the amazon_attributed_events_*tables contain ad-attributed conversions across all of your Amazon Ads media,you can aggregate them by sponsored ads vs.Amazon DSP using the__________.

The conversioneventcategory field is the correct choice because it directly categorizes the type of conversion event, allowing you to differentiate between conversions originating from Sponsored Ads and Amazon DSP. This field provides the necessary granularity to aggregate and analyze performance by ad product. The supplysource field indicates where the impression or click occurred (e.g., Amazon, third-party exchanges) but doesn't distinguish between Amazon Ads products like Sponsored Ads and DSP. The trafficeventtype field describes the nature of the event (e.g., impression, click) but not the ad product responsible for the conversion. The adproducttype field might seem relevant, but in the context of amazonattributedevents tables, conversioneventcategory is the standard and most precise field for this specific differentiation.
