I've been working in online marketing for e-commerce stores for years, I know a little about everything and I'm an expert in some things.
I always wanted to start my own store, but I've never been sure about how to do proper product research.
Can you recommend sources that talk about this in-depth? I'm sure there are software, website, people, coaches, groups, forums, etc that could point me in the right direction.
Do you know any that you've found helpful??
