I like Seller Tools ease of use. I was able to get this going without much effort. It was also easy to understand. As a new Etsy seller a lot is confusing, but this wasn't.
I like the possibility of being able to automatically post my Etsy listings on my Facebook page, so even when I'm busy and I'm not at the computer Seller Tools does the job for me. I have increased a lot my shop views and sales thanks to Seller Tools!
I like the tools that are offered, I really appreciate how easy they are to use. The whole site is very intuitive. I also like the amount of information we get from the tools, especially the SEO function, this is all very helpful!
