As a Multi-Million Dollar seller, Key-note Speaker, well respected authority on conversion and product launches in the AMZ community, Titan mentor, and someone who has helped more than 800 brands gain momentum on Amazon - let me tell you that not everyone succeeds on this marketplace.
The reality of the situation is most sellers who get into Amazon expecting to immediately rake in profit and find gold, end up seeing their margins decline, their revenue stagnate, and their visibility slowly drop.
This is because Amazon is a highly competitive marketplace with new competitors cropping up every minute, rising CPCs (advertising costs), rising freight costs, and an evolving Terms of Service that has made it challenging (some would say impossible) to run rebates or source reviews.
