Amazon has shifted from primarily keyword-based ranking (A9) to a more performance-based system (often called A10). Amazon cares less about what you say your book is and more about how readers respond to it. Amazon watches: - Sales consistency - Click-through rates - Conversion rates - Reviews - Kindle Unlimited reads - Performance during the first 30 days A huge launch spike followed by silence is less valuable than steady sales for a month. So before you publish, get together with @Krista Brea and map out your 30-day blueprint-to-launch day. It will make a world of difference!
