I use the following tools and resources in my business when selling on Amazon and to my retailers
Disclaimer: some of the links are affiliate links and at no additional cost to you, I will earn a small commission if you decide to make a purchase. I have personally used and tested all of these products or companies, and I recommend them because they are helpful and useful, not because of the small commissions I make if you decide to buy something. The cost to you remains the same, sometimes even cheaper if I have negotiated a special deal for my readers.
I use these tools to research numbers, optimise listings, test ads, split test and much more
