If your self-published book is available for sale at Amazon.com, Barnes & Noble (BN.com), and other sites, you want to be sure your online listings have book reviews. You can always be sure your book has at least 1 review by asking one very close friend or relative to write a review for your book.
Once you have one review, your job is to solicit others. Obviously, if you’ve given some of your books away to friends or families, you should ask them to write a review in exchange for the book. As you continue to give them away, suggest to your customers that it would be helpful to you if they took the time to write an honest online review. People like to help people, but usually only do so if you ask.
BONUS: Once you have reviews, you can use them in quotes for further promotion. For example:
“Best Book Ever!” — Amazon.com review.
Your book detail page on Amazon and Barnes & Noble have links for writing reviews of your book. If you haven’t done that yet, do it right away.
Remember, in order to write a review for a book on Amazon, each reviewer must have an Amazon account with which they have purchased something. This is how Amazon verifies the identity of the reviewer. They don’t need to buy your book, per se, they just need to buy something, anything, from Amazon. But it is nice if they DO buy your book, so suggest that to your friends first.
Good luck and have fun!
