Kelsey would like to review her campaign delivery over time. Which of the following Dashboard Breakdowns should she apply?

The "Date" breakdown allows Kelsey to analyze campaign delivery trends and performance metrics over specific time periods. This is crucial for understanding how her campaign is performing day-to-day or week-to-week, identifying patterns, and making timely optimizations. "Country," "Community," and "Interest" breakdowns are useful for segmenting performance by audience characteristics, but they do not show delivery over time. While these breakdowns can help identify where or to whom the campaign is delivering, they don't illustrate the temporal aspect of delivery that Kelsey is looking for.
