Are you the type of writer who feels sure you possess the expertise to write your book or are you the type of writer who questions whether you are good enough to do so? Do you know you are the best person to author the book you have in mind, or do you wonder if someone better exists?
Either way, you must convince your readers you are the expert on your subject. Indeed, you must tell the world you are the only person who should write this particular book.
And now you must write down all the reasons why you, indeed, are the best person to write your blogged book. In a nonfiction book proposal, this section is called “About the Author.” Sounds pretty simply, right?
It can prove simple—or hard. That depends upon you. You write a biography of your expertise and experience, and you do this using the third person tense. You include the most important facts first, such as anything that makes you the expert on your topic, your educational degrees (if they apply to the topic), work experience, etc. Include all your achievements. See this as your resume in prose but written specifically for your book.
Obviously, an aspiring author who wants a deal with a traditional publisher needs to create an “About the Author” section for inclusion in a nonfiction proposal; the proposal is necessary to sell the book. However, a blogger needs a biography (bio) as well. Every blog should include an “About” or “About the Author” page. This allows readers to find out who you are and why you have the expertise to write your blog. This information gives your blog credibility.
So, write your bio and pace it on the “About” page of your blog. If you prefer to use a less formal bio for your blog, write it in the first person tense using “I.” If you write your blog in a more formal voice, though, stick to third person for your bio as well.
