Reviews might seem like a small part of book promotion, but they actually play a huge role in reader decisions. Most people check reviews before buying anything online, and books are no exception.

While reading a Guide to Book Marketing, I found an interesting point about early reviews shaping a book’s visibility. Platforms often recommend books that already show reader engagement.

That means even a handful of thoughtful reviews can help a book gain momentum. Authors sometimes encourage early readers or beta readers to share honest feedback once the book launches.

What matters most is authenticity. Readers can usually tell when reviews are genuine. Honest opinions, even mixed ones, tend to build more trust than overly perfect feedback.
