The Five Star Method
It’s a quick glimpse into the opinion of the majority of readers, but remember--it’s an average. If a book has only a handful of reviews, a negative one could shoot the average down pretty quickly.
The Super Fan
All authors want them. And why not? They make fanfiction, memes, and countdowns on their blogs until the author’s next release. In short, they’re awesome. But. All that adoration can lead to reviews that aren’t always helpful. Rose-colored glasses can make it hard to give an honest critique.
The Negative Nancy
Why oh why did anyone EVER publish this book?! It's so stupid. The author is a joke. I write better than this. My senile cat with bladder control issues writes better than this.
There’s a fine line between a good review of a 'bad' book and a bad review of a 'bad' book. I'm not talking about if a reviewer thought a book was a total flop. That, they're more than welcome to say. Unfortunately, we've all seen a review or two where a person's moral compass seems to be stuck in the a$$hole direction. If a review only serves to mock, degrade, or slander the author and doesn’t focus on the book’s issues, it won’t be helpful.
Pay Attention to What They Say
What someone felt was cliché might be your cup of tea. I’m an avid urban fantasy reader and have enjoyed reading several books with reviews claiming it was too expected and typical. Everyone has their own personal taste, which is why it’s important to look for common complaints that are your own pet peeves when making a decision about a book.
How much of your book buying is based off reviews you've read?
