Every author will face it: bad reviews. Some more, some less, but in all cases they will hurt. Bad reviews come mostly because your book came into the wrong hands: that reader wasn’t supposed to read your book but based on your cover or summery they thought they are and they read it. So, a large part of potential bad reviews can be avoided with careful considerations when deciding on your metadata: genre selection, book covers, blurbs and such. But even if your metadata is spot-on, you will still end up with some readers that were never meant to pick up your book in the first place. Here is how I dealt with mine.
What to write in a review and why you should
What’s a good book?
A good book is when I can’t wait for my next available free time to sit and read the next few pages. When I read the page on the left and my eyes keep jumping to the page on the right, desperate to find out what will happen. A book that I often rewind: I go back to read a paragraph again and again, because I really liked it. A story where I identify with a character: someone who is good, brave, but still has some minor faults I can relate to.
