I'm certain we've all gotten a negative review. The one-star review or a review where your book is literally torn to pieces leaving you ragged and raw. Every one of us has had to deal with such a review at one point or other in our career. It's not the review we must worry about, but how we deal with it.
Many years ago, (10 years or so) I got some amazing advice from my publisher at the time. She told me to consider how my life had altered and for me to consider what it meant to have a book on the market. For better or worse, I was a public figure, even if it was only to a select group of people. What I did was being watched closely.
Her words ring true even now after she's retired and I'm working on book number...thirteen or so. In some ways, my life altered with the first contract, in other ways, it's still the same. For me, the biggest difference is how much thought I have to put into what I say online.
Okay, I can hear you say, "Nonsense, what could possibly have changed?"
Well for starters, I had to be aware of getting into controversial arguments on social media. Not that I was into them, to begin with, but I've seen some authors who have lost their s**t over a bad review, or some percieved personal attack. I'm all for defending one's self, especially in light of some of the negatives out there such as Piracy but that's another topic for another day.
Reviews are a keystone for authors, you need them to create sales. Unfortunately, you need sales to get reviews. It becomes an endless cycle of hope and prayer, lol. But let's get back to the topic - I meandered away there, my apologies. We write this book, pour our sweat, blood, and tears into it. It becomes a living entity to us. After weeks, months even, of work, it's published and on the market. And we want people to love it, but you check and see a *gasp* review. Reading it, the anger rolls, steam's bursting from your ears, and you're ready to throw the laptop out the window.
How dare someone tear it apart? What do they mean giving it a single star?
Guess what, it happens.
The way we handle it will set the tone for ourselves and our reputation as authors. No, you don't toss out the laptop or break things. It won't change anything, and you'll have to clean up the mess. Instead, take it for what it's worth. A review is a reader's opinion, and there is very little likelihood you're going to satisfy every person who picks up your novel.
So we have to balance it out. Yes, a negative review sucks, but if we expend all our energy on that one review - what's left. In my experience, and I make no implication I'm speaking for anyone else, the best way to deal with the negative review is to pick it apart. What is the reader telling me? Was there some plot hole which I didn't see and it pulled the reader from the book? Maybe it was pacing? Is there a kernel of information within the review I can use?
If you can answer any of these questions positively, then I would say make this a positive review.
One thing an author should never do is attack the person leaving the review. If you want to lose any credibility, or gain a bad reputation then engage in an all out troll war.
Now, if there is no way to look at the review in a positive light for whatever reason, then just getting passed the review is your only option.
Put your energy into a more positive endeavour such as writing. There is never going to be a day when you will please every person who reads your book. And it's been proven, bad publicity can work in your favour. Keep in mind, reviews are opinions, and trying to force, cajole, or otherwise please everyone so you get nothing but 5 star reviews will ultimately hurt you when you suffer burnout.
