I use Seller Tools to tweet my Etsy products. I love the automated feature meaning I just had to set it up once and leave it to tweet automatically for me. I liked that I could choose my main product photo for my tweets and the frequency of tweets. I have noticed increased views on my Etsy shop directly from the Seller Tools auto tweets!
I love the fact that I can easily join a favathon event in seconds and I do not have to follow the thread to be able to join, like with other favathon games on Etsy! Here I just select an item and people start liking it almost immediately. This is really cool! I also loved how Seller Tools can automatically post items from my shop on my social media - I just select the items that will rotate, I select how often my products will be posted and all is ready! This is a great help to busy Etsians. I also liked how Seller Tools give me a summary of other Etsy users and I can see all of their feedback's they have left. Amazing!
