Readers choose books based on recommendations. Leaving an Amazon review is like telling your friends how much you enjoyed your latest read.
After 20-25 reviews, Amazon includes the author’s book in “Also Bought” and “You Might Like” lists. This increases the visibility on the site and helps boost sales.
After 50-70 reviews, Amazon highlights the book for spotlight positions and its newsletter. A HUGE boost for an author.
