Stick to the tried and true! Using Amaozn’s own best seller lists is much better than Jungle Scout, Viral Launch, look where people aren’t because that’s where the treasures are!
Everyone is teaching how to sell on Amazon with software that 1000’s of other people are looking at. That’s troubling!
Go through Amazon’s lists daily and get notifications and updates on new releases, movers and shakers, etc.
Also start to look outside of Amazon for product validation!
