I'm focusing on growing passive income with Amazon KDP.

I currently have 21 Amazon Ads campaigns running and I'm concerned that this might be affecting my profits.

I spend $17 to $45 a day on these campaigns, with some days having zero sales and occasional small losses.

Despite challenges, I've managed to 2x my return since starting in January and even hit a 4-5x return in the previous month.

I'm experimenting with different books in my campaigns, turning off underperforming ones, and will soon share my October KDP income report.
