Achievements
It’s likely your bio will include awards or achievements in relevant fields to the topic of your book. (This is especially important if you are backing up your authority to speak as an expert with a nonfiction title.) I say relevant because an overly enthusiastic inclusion of accolades could end up disjointed and confusing for readers. For example, the author of a book on fly-fishing does not likely need to say that he won the Great Chili Cook-off Award at the local Rotary Club. A Best Trout Catch might be a fun thing to include, though! Staying on theme will help your bio remain relevant to your readership.
Personal Information
Often, author bios include some personal information such as where the author lives (and who with), and maybe even a few hobbies he or she enjoys (especially if they are somehow of pertinence to your writing subject matter). Mentioning clubs or associations you are a member of is also an important piece of personal information that may cultivate additional professional credence. Our fly-fisher might have a line about where he prefers to fish, which will create connection points to local fishers in that area.
Educational Background
Sometimes, your educational history makes sense to include in your bio. If you attended a prestigious institute it’s probably worth mentioning—your yearlong stint at a community college is likely not the type of education you need to include.
Contact Information
The last piece of your author bio puzzle is your contact information. Making sure to list your author website, twitter handle, or other way for readers to find out more info about you is a vital part of building your author brand.
