Each time you read something interesting you probably look at the author’s name. The same rule applies to your readers. As an author, you can benefit from providing the general reading public with the opportunity to know more about you and your work.
The author biography is where you tell people about yourself and build trust and authority. In a impersonal medium like the Internet, a well-crafted biography must show integrity and effectively develop a rapport with readers. A great bio creates a perfect balance between personal information and achievements to build familiarity.
I’ve always had an abundance of material about the subjects of my biographies. – Walter Isaacson
Sincerity is key to delivering a more human approach that is worthy of loyal readers. If you have professional credentials or big achievements, blend in that info in a way that will not come across as egocentric or pompous. Having an author website will give you the opportunity to expand on that information more extensively in a separate section.
Talking about how life experiences are related to your writing will add an extra level of consistency to your work and, by extension, to your books. Include your photo or provide readers with a picture that could be associated to your name and your style.
Online readers are used to interactivity so they are more willing to connect with authors, provide feedback, ask questions, and leave comments. So, be sure to provide your contact information and a link to your website where they can share thoughts and ideas.
Your author bio is a great tool to make your readers interested in your next book even before you complete the final draft, providing them with the tools and opportunities to help you make a living doing what you love.
