Amazon's New Discovery Algorithm
- Amazon rolled out a new discovery algorithm (A10) that appears to change how books are recommended and affects authors' ability to plan.
- Algorithm shifts make it harder to create repeatable launch systems that reliably replicate past success.
Create Repeatable Publishing Systems
- Break publishing work into repeatable chunks (metadata, description, cover) to create systems you can replicate.
- Use operating procedures so algorithm changes don't force you to reinvent your process each release.
Author Report: Rank Volatility, Not Sales
- Rachel McLean reported sales stayed steady while bestseller rank became more volatile after the algorithm change.
- This suggests rank fluctuations may not always reflect actual sales volatility.
