I'm sharing a $5 Amazon Ads Strategy for KDP books. I recommend starting with a $5 daily budget and a 2-cent bid amount for automatic ads, adjusting the bid amount every two days or hours based on performance.

The key metric to watch is the click-through rate (CTR), with a 1% CTR being ideal for conversions. If your ad isn't generating sales, consider increasing the budget gradually or revising the ad copy and book description.

Additionally, I stress the importance of finding underserved niches and validating them for success in Amazon advertising.
