Hi i have some doubts about publishing a book on amazon kindle that im sure someone here will know. 1. How much time do they usually take to approve youre book? -Content is 100 % original so im not worried about that, but i suppose they will analyze the book and think seriously if its worth for them to publish it with the estimated earnings they calculate they would get. 2. If they publish it, will they take the book down after some time if it doesnt have what they consider enough sales? 3 . Also i suppose you could post on social media,blogs etc to get your book ranked to the top of your book category?
