How do I retarget people on different devices through a DSP?

[Daniel]

To retarget across devices using a DSP, you need to use a tracking system that can recognize the same user on mobile, tablet, and desktop. This usually works by combining cookies, device IDs, and sometimes login data. When someone visits your landing page or clicks your ad, the DSP adds them to a custom audience. Later, when they use another device, the system tries to match them and show them your ad again. It’s not always perfect, but with the right setup, it helps keep your ads in front of the same person. This can improve conversions since people often switch devices before buying. Do you already use cross-device targeting in your campaigns?
