I'm writing my first eBook about micro-entrepreneurship that's called Start With A Side-Project -
https://gum.co/side-project.
So far I'm only offering it on Gumroad, I actively promote it since I'm a first-time author so I don't expect to be recommended by Gumroad.
How does the discoverability on Amazon works? Will I have to put efforts promoting it there as well? I might as well just focus on promoting my Gumroad page instead of promoting two links.
