We are currently doing a little work on our Analytics, so you may not be able to take full advantage of our dashboard at this time, but once we get things rolling again, you can check your # of shares beneath the 'Views from Social' column on the right. Here's a sample data report where you should see all of the available headlines and some details to get an idea of how things will look in your report. And don't worry, the Analytics dashboard usually saves your data for a 30 day rolling period--but this is one of the things we are performing some maintenance on at the moment.
I hope you find this information helpful! :)
