Within Display & Video 360, when would you use data-driven creatives with dynamic rules?

Data-driven creatives with dynamic rules are used to personalize ad content for individual users based on specific criteria. This allows you to customize each creative within your campaign to show different messages, images, or calls to action depending on factors like audience segment, location, time of day, or past interactions. This level of customization enhances relevance and engagement. Customizing creatives for mobile apps is a use case for dynamic creatives, but it's not the only use case, nor does it fully encompass the power of dynamic rules. Building and directly uploading creatives to Display & Video 360 describes a general creative workflow, not the specific application of dynamic rules. Measuring performance is a separate function of reporting and analytics, not the primary purpose of data-driven creative development.
