I'm sharing my journey of growing passive income on Amazon KDP.

I've used seven strategies to scale books, and now I'm excited about a new ad strategy using Book Bolt.

This software is tailored for Amazon Kindle Direct Publishing, helping me find successful self-published books and discover valuable keywords.

My latest ad campaign, started in November, demonstrates the power of patience in scaling ads, achieving a low A-cost and emphasizing the importance of second-round keywords for success.
