Case Study

Amazon Ads for a KDP author: 9.63x return on ad spend in 2026

The Goal

A KDP author needed more sales and visibility in a crowded category, without letting ad spend eat the royalties.

The Challenge

Every dollar had to earn its place. Push too hard and ACOS swallows the profit; hold back and the book stays invisible.

What I Did
  • Researched high-intent, low-competition keywords
  • Wrote and A/B tested ad copy around readers' real pain points
  • Reallocated bids and budget weekly from performance data
  • Split campaigns by reader intent and funnel stage
The Results
10.39%
ACOS, January to October 2026

What It Meant for the Author

Spend scaled only when the numbers held, so growth stayed profitable. See the performance metrics →
