Question: When should an advertiser consider using bid modifiers?
- When they want to reduce manual control over bidding
- When they want Amazon DSP to automatically optimize bids for standard campaign goals
- When they have additional data not available to Amazon DSP that informs the value of impressions
Explanation
Bid modifiers are useful when advertiser-owned signals can improve how impression value is evaluated in Amazon DSP. They allow bid adjustments at bidding time using criteria such as domain, app, device, location, or audience. This works alongside Amazon DSP automated bid optimization rather than replacing it. The feature is intended for cases where custom business logic adds value beyond standard optimization inputs.
Why the other options are incorrect
A is incorrect because bid modifiers add advertiser control rather than reduce it.
B is incorrect because standard automated optimization does not require bid modifiers.
