Custom audience lists in DSPs are useful because they allow you to target ads to people who have already shown interest in your brand or product. These lists can include past website visitors, email subscribers, or people who interacted with a previous campaign. When you use them, you’re not starting from zero. You’re reaching people who may be more open to your message. This helps improve engagement and cuts down on wasted impressions. You can also build lookalike audiences from these lists, which can help you find new people who behave like your best users. It’s a smart way to keep your ads focused. Does anyone have thoughts on using custom lists this way?
