What is the most useful for me is that I can schedule posts for my shop throughout the day. Even if I was sitting at my computer all day long, I wouldn't be able to keep posting for different time zones worldwide.
The sales event manager is simple and effective. I have also used the reviews manager for posting on social media. It is great and helps to gain followers.
I use the social media productivity tool for posting to Facebook and Pinterest etc. The reporting is very good - showing what is doing well and categorizing all sorts of things.
