¿Cuándo debe un anunciante considerar usar modificadores de oferta?

Advertisers should consider using bid modifiers when they possess additional data, unavailable to Amazon DSP, that provides insights into the true value of impressions. This external data could include offline conversion metrics, customer lifetime value (CLTV) estimates, or proprietary audience segmentation that Amazon DSP's standard optimization algorithms don't fully capture. By applying bid modifiers, advertisers can manually adjust bids up or down for specific segments (e.g., audience, geography, device) to align with their unique understanding of impression value, thereby optimizing campaign performance beyond what automated bidding alone might achieve. The other options are incorrect because: "When they want Amazon DSP to automatically optimize bids for standard campaign objectives" describes the primary function of Amazon DSP's automated bidding strategies, not a scenario for manual bid modifiers. "When they want to reduce manual control over bidding" is the opposite of using bid modifiers, which inherently increases manual control.
