The scheduled Twitter and Facebook posts are working!!! My traffic has almost doubled in the first week of using this tool. I have worked hard for the last year to create 900 followers on my Twitter account and its working because some of my items are being seen by over 10K people!
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.
