One of my hugely informative author profiles. Don’t do this.
Author profiles are an essential part of book marketing and promotion. An author profile is a mini-biography. It tells something about the author that will interest the reader, includes a headshot, and links to the author’s books. Depending on where you post your profile, you can also include a link to your website or blog, events, videos, and answers to questions posed by readers.
Profiles are useful for several reasons. First, anyone who has enjoyed your book will want to find out more about you. And second, your fans will want to read other books by you. Third, profiles provide an avenue for engagement with readers.
