Since I've enrolled in the course on how to be an Amazon product researcher, I,'ve learned the different methods on sourcing such as manual sourcing, reverse sourcing, storefront stalking, keepa sourcing and sellerampsas sourcing.
I've also learned to use the keepa on analyzing the graph, filtering on faster sourcing, and see the other essential information about the product to see if its a good deal or not.
In addition to that, I am also using sellerampsas in storefront-stalking and for faster computation of the roi, profit and so forth
