I have published 12 books so far, combining both fiction and non-fiction in different niches to test the organic traffic. No low content books, all books I have published have atleast 170 pages long. Here's my latest stat for this month,How many shorts do you post per day and what is the country of majority of your traffic?
How many books did you publish and how many of them are making you money? Are they fiction or low content books?

Note: All this earnings from organic. I didn't run Amazon ads yet.
