I'm discussing three key secrets about ACOS (Amazon Advertising Cost of Sales) for KDP businesses.

Firstly, I recommend creating high-quality books with higher price points to allocate more funds for advertising.

Secondly, I explain that raising book prices doesn't necessarily hinder sales, as Amazon may adjust prices while maintaining your royalties.

Lastly, I advise focusing on overall account ACOS instead of individual campaign or book ACOS, which allows for better budget management and profitability assessment.
