I tested it by using it, then not using it. The "not" using it was hard. I found it much easier to schedule the posts, then forget about them. I did wish that I could have put more specific information for Etsy teams on Twitter so they would be caught by them better. but the pictures worked extremely well. I found I expanded my target audience using the system, and sold more, which is the bottom line.
I really like the fact that there is so much information here. I have really learned a lot about how to market my Etsy site. The sale I have going is really helping my sales and my brand name is being recognized. The hourly postings to FB, Pinterest and Twitter are such a time saver for me. You also have great "help". The person I talked to answered all of my questions perfectly and even gave me more "tips" on how to promote my site.
