On the Overview page, social app users are able to see more information regarding scheduled posts, post-performance, and customer posts. You can also see how many scheduled posts are coming within the next 30 days, how much engagement posts have received within the past 30 days, and how many customer posts have been made by your fans.
Having more social data on the Overview page allows you to get a better understanding of how your social media strategies are performing at a glance.
You simply need to compose and post/schedule social media posts to see these analytics.
