Helpful info, saved for sure. I have 4 books on KDP. My latest novel sold 3 copies -- 2 to family members and 1 to a friend. So clearly I am the worst marketer in the history of marketing. Web sites, blog posts, social media posts on FB & Insta, Twitter posts, even tried a couple of ads on FB & Amazon -- not even one sale from all of that. Granted, maybe my book simply sucks, lol...
