Did you know that you’re allowed up to seven keyword strings on the back-end of your Amazon book page? That’s right! That means that you can use search strings that readers would plug into the Amazon search bar to take them right to your book. Think of search strings like “how to sell more books on Amazon” or “new romance books” – both of these are popular searches on Amazon.com. Just make sure that your keywords match your book’s benefits to the reader!
