From my background as an educational psychologist, I know that all learners can improve by studying the methods of experts no matter what the field. How can I identify top sellers in my product area in order to study them? Specifically, when a seller says she is the "fourth largest seller of vintage jewelry on Etsy," how did she get that information? How do I learn skills like managing the re-activation of items so that they will be relisted as new items for the weekend? I feel as if I'll never know the Etsy "secret playbook" top sellers have constructed for themselves by virtue of their experience. Any suggestions for resources for this info?
