If you took the time to develop and market your products, you would not have solely relied on Amazon e-commerce. Most likely, the single greatest source of traffic was Facebook (Instagram) and Reddit. You would only sell on Amazon, if you’re from EU (or RoW) and that Amazon US made sense for you in terms of logistics. In other words, if you solely relied on Amazon to make money that means your business model was BUILT on fooling consumers on Amazon algorithm not your actual product.
