I really like the never ending list of tools that is available to me! The weekly reports give insights on what is working and what is ultimately a waste of my time. Most of all, I like the keywords/tags analyzer and how much it helped to get my products that had little to no exposure seen.
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!
I like Seller Tools ease of use, clear categories and uncluttered design. Sorting possibility in your shop analytics is amazing, I really love to see which products are my top performers.
My sale just started and I've had increased views on the sale items. I like the added exposure to my products and the fact that Seller Tools assists sellers.
