Once a book is published, there are two things an author hopes for: sales and reviews. Sales are good because they allow a writer to be financially supported as they write their next book. Reviews are good because they lead to more sales. And the more stars each review has, the more validated the author feels and the more confidence potential readers have.
But regardless of whether a book is good, bad or somewhere in between, and assuming it has had enough exposure, it will have each of the following types of review.
The Never-Read-It Review
Obviously someone who reviews a book they’ve never read has a nefarious purpose, either to promote or prevent the reading of it. Platforms like Amazon usually don’t allow a review of a product that hasn’t been bought directly from them so that helps a little. Platforms like Goodreads rely on the honesty of the reading community they have assembled. It doesn’t always work.
