Revenue since launch (Aug 2020) - $5,688
So far this month I've earned $450. Compared to last month's $5,238 it is a massive difference BUT it is important to remember that a large chunk of those sales came from my Product Hunt launch.
All sales now are from referrals, word of mouth and just general organic reach which is great. I've also noticed that Gumroad is starting to recommend my book to its audience.
If I can earn a steady $2k a month from this ebook then I will be very happy.
Time will tell.
