What method(s) of optimization does Amazon DSP offer?

Amazon DSP offers both manual and automatic optimization methods to help advertisers achieve their campaign goals. Manual optimizations involve direct adjustments by the advertiser, such as changing bids, targeting parameters, or creative assets based on performance insights. This provides granular control. Automatic optimizations leverage machine learning algorithms to continuously adjust campaign settings in real-time, like bid optimization or dynamic creative optimization, to improve performance against defined objectives without constant human intervention. Both methods can be used independently or in conjunction to maximize campaign effectiveness. "Neither of these" is incorrect because Amazon DSP explicitly supports both approaches.
