Which of the below are best practices when setting up Amazon DSP campaigns?

Breaking out line items by device type, audience, and supply type (Amazon O&O vs. third-party) allows for more granular control over bidding, budgeting, and creative optimization. This segmentation helps tailor strategies to specific contexts, improving campaign efficiency and performance. For example, you can allocate more budget to high-performing device types or customize creatives for different audience segments. Setting up cross-device campaigns is crucial for reaching audiences consistently across their various touchpoints. Users interact with content on multiple devices throughout the day, and a cross-device strategy ensures your ads are seen regardless of whether they are on a desktop, tablet, or mobile phone, leading to more effective engagement and attribution.
