¿Por qué un anunciante debe cargar todos los tamaños de los materiales creativos disponibles durante la configuración de la campaña?

Uploading all available creative sizes allows the Amazon DSP to test different variations and optimize delivery towards the best-performing creatives. This A/B testing approach ensures that the ads most likely to drive engagement and conversions are shown more frequently, maximizing campaign effectiveness. Reducing setup time is incorrect because uploading more assets takes longer initially, though it saves time later in optimization. Increasing campaign reach is incorrect; reach is determined by targeting and budget, not creative variety. Maximizing visibility is also incorrect; while good creatives help, visibility is primarily driven by bid strategy and ad placement.
