Lately there has been a lot of conversation on one of my face book groups about reviews on Amazon, and whether you should respond to them. Okay, I would think that's a no brainer. There are a few people who are adamant about not responding to reviews on Amazon. Even if they're good reviews. I have to say I disagree! You should respond to all reviews.
When we receive reviews from professional review sites, we're encouraged to thank the reviewer. I always send a short note or leave a comment on the actual review. Even if it's not so good. I believe it's even more important to respond to your reviews on Amazon, since they are unsolicited and from readers. Don't you think they deserve to know how thankful you are that they took the time to read and review your book? Hell yes!
It's called common courtesy, folks!
