I'm discussing how a single book I created generates $4,000 in monthly revenue.

I started by identifying an underserved niche in February and utilized Amazon KDP ads to promote the book effectively.

The book's Best Seller Rank (BSR) is currently at its lowest, and I have made $28,394.89 in profits to date, highlighting the importance of well-searched keywords and underserved niches for success in self-publishing.
