Delivery Insights is a dashboard that can help you better understand the performance of your ad sets. It shows you metrics about your ad delivery, the dynamics of our ad marketplace and how the two are related to each other.

Delivery Insights is useful not only for tracking performance changes, but also understanding what may have caused them. It can also help you decide what actions to take if you're not getting the results you want.

You can view these metrics in the dashboard's tabs and then use the Activity history tab to see how they correlate with recent actions you've taken.
