I'm discussing the significant impact of running Amazon ads for a single book on Kindle Direct Publishing (KDP).

I share my success story, where daily book royalties increased from $6 to $20 through well-managed ads.

By demonstrating a screenshot of my low-cost, high-sales ad campaign, I highlight the value of ads in increasing book sales.

Ultimately, running ads not only boosted the profits for the featured book but also significantly contributed to my overall earnings from my pen name's entire book collection, reaching over $1,500.
