You can access your Analytics page by opening your Profile Menu, then selecting Analytics from the list.
The Analytics page itself is divided into two parts: the list on the left and the graphs on the right.
On the left, you'll be able to find a list that gets more complete the more you post and get interactions on your posts. Everything from overall Posts Engagements, to Organic and Paid views, Clicks, Followers, Profile and Topic visits, even an individual breakdown for all of the topics you moderate. When you wish to analyze one of these, select it from the list and the graph on the right will focus on that category.
Now about the graph. Each graph has a few other bits of information related to it. Above the graph, you'll see the total number of engagements you got yesterday, along with a percentage indicator, as well as today's current engagements, together with a projected number for the end of the day. On the right, you'll find a list of the Last 30 days and the total number of interactions for each day.
At any point and on any graph you want, you can switch the stats to show you the Monthly breakdown, instead of the Daily one that shows up as the default. The same logic applies for the stats shown here: Previous and Current Month above the graph, as well as the last few months on the right.
Note that in order to see individual post engagements, you can check the Engagement stats on individual posts. The Analytics page is designed to be an overview of your entire activity on Sharesome and give you an idea about which aspects you should focus on.
