When viewing Insights for your account, you’ll see a line graph showing activity over time. Hovering over the graph allows you to see totals for each day. You can view your data for any of the following timelines by selecting the range of interest on the top right of your screen: last day, last week, last month, last year, or all plays.
Click on a track and select the All Time option for a detailed look at a track’s stats over its lifetime. Analyzing a track - especially around key moments in a campaign - is a great way to help you make informed decisions for future projects.
