Insights is a tracking system to the views on your presentations, along with other stats. Access from your Dashboard, by hovering over a presentation and clicking on Insights.
When working on the slides, from the presentation Editor you can find Insights on the bar menu.
This dashboard will display three metrics being tracked from your presentation shares: Total views, Average time from viewers on the slides, and an Average completion rate from the views.
Look at each metric within different time periods, by choosing from the drop down menu. Data will be displayed on the line chart, along with a log from the viewers.
Click on each log and display individual data for that view. Viewers who haven't signed up or entered their email address, will show as Anonymous.
