I've recently become extremely interested in Amazon stores and I want to start a big project in the coming months. I'll rep+ those credible people who answer below questions. I'm planning to open an amazon review site and an amazon store and test which brings in more profits but if someone can tell me which works better then it'll save me so much time and money. Also regarding SEO for "Amazon stores", do you target the main domain for every keyword or do specific keywords go to different categories on your store? this questions has been bugging me for awhile. Also are there any decent amazon ebooks you guys recommend? most i've found seem to be short term "methods" i need something for long term business. I'll rep+ credible people who answer those questions thanks.
