What Not to Include in a Professional Bio?

Avoid: unverifiable claims, excessive superlatives ('best,' 'top,' 'world-class' without proof), personal details that don't serve the reader (age, marital status unless relevant), negativity about past roles, humor that could offend, and jargon that obscures meaning. Don't list every job you've ever had—focus on what's relevant. Avoid humblebragging. Skip political or controversial topics unless central to your brand. Don't copy someone else's bio. And never lie—it catches up.
