¿Qué tabla deberías usar en una consulta destinada a ayudarte a elegir nuevas audiencias de Amazon que puedan beneficiar el desempeño de tu campaña de Amazon DSP?

The dspimpressionsbyusersegments table is the correct choice because it contains data on impressions attributed to specific user segments, including Amazon-provided segments and custom segments. This allows you to analyze which segments are driving performance (or underperforming) and identify new, high-potential Amazon audiences to target with your Amazon DSP campaigns. The dspaudiences table lists available DSP audiences but doesn't provide performance metrics. The amazonaudiences table is not a standard AMC table. The dspimpressionsbymatchedsegments table is similar but focuses on matched segments, which might not always directly translate to actionable Amazon audience selection for new targeting.
