Describe your book. Sure social media is a great way to promote our books, but we don't really have a chance to thoroughly discuss our work. With social networking all we have to do is write a catchy sentence and post a purchase link. In an interview, you can discuss your book as much as you want. Talk about the plot, the characters, inspiration, and what sets your book apart from the rest in the genre. This is your time to engage readers and get them invested in your book.
Give readers a glimpse into your life. Fans are always curious about the lives of their favorite celebrities; including authors. Some people are shy and don’t like to discuss their private life, that’s okay, feel free to share as much or as little as you want. Just cover the basics such as your home town, if you attended college, and your family. I come from a crazy family and I don't mind talking about them in interviews.
Show your personality. We all have an uninhibited side to use that people may not know about. For example my favorite show is Duck Dynasty, I love to read books about UFOs, and I have a tattoo. Judging by my picture, you never would have guessed that about me, but that's the kind of person I am. Interviews offer questions about a person's hobbies or their favorite things, so don't be afraid to cut loose and show your fun side.
