I'm emphasizing the significance of niche specialization in Kindle Direct Publishing (KDP).

I draw upon my own experience of building passive income on KDP since January 2022, highlighting the importance of niche down to address common challenges like idea generation and competing in saturated categories.

I also promote my live training course on the keyword niche formula, offering a 20% discount with the code "bookish" until Saturday, aiming to help individuals develop niche skills and enhance their success in KDP.
