Authors can ask readers for Amazon reviews. The problem starts when the request becomes pressure, payment, or a request for praise.
A safe review request is short, neutral, and easy to ignore.
Use Honest Language
Ask for an honest review. Do not ask for a positive review. Do not mention a star rating. Do not give readers a sentence to copy.
A good request is simple: if you read the book, an honest review on Amazon would help other readers.
Do Not Add Rewards
Do not offer money, gift cards, refunds, bonus chapters, free services, or future favors for a review.
If readers received an ARC, the review should still be optional.
Keep The Timing Natural
Send one request around launch and one reminder later. Avoid telling a large group to post on the same day.
Natural review growth is slower, but it is safer.
