Which bio length do you actually need?
Three lengths cover every slot: the one-liner (under 25 words) for bylines and social profiles, the short bio (50 to 75 words) for book pages and guest posts, and the long bio (100 to 150 words) for your about page and media kit. Write the short one first — the others are cuts and expansions of it.
Never write just one length and squeeze it everywhere. A 150-word bio crammed into a byline looks amateur; a one-liner on an about page looks thin. An hour here outfits every slot at once.
What is the credibility formula?
Who you help, plus the result, plus one proof, plus one human detail. “Maya helps new freelancers price their first project. Her templates have been used in 2,000 proposals. She writes from Lisbon with strong opinions about invoices.” Four sentences, zero fluff — and the last one makes her a person instead of a logo.
Proof beats adjectives every time: numbers, roles, and named outcomes (“priced 40 projects”, “teaches 300 students”) where “passionate guru” would sit. If you lack big numbers, use specific small ones — “helped 12 clients” out-converts “helps countless clients”.
A bio needs a book behind it.

What does a finished set look like?
One-liner: “Maya Chen helps new freelancers price their first project.” Short: add the book and the proof — “Maya Chen helps new freelancers price their first project. She's the author of The Freelancer's First $1k, and her pricing templates have been used in 2,000 proposals. She writes from Lisbon.” Long: add backstory and the human detail — how she started, who she teaches now, the invoice opinions.
Same facts, three depths. Write them in that order — one-liner, short, long — and each longer version just unfolds what the shorter one compressed.
Which bio mistakes undermine trust?
Third-person pomposity (“a visionary thought leader”) that nobody believes, credential-stuffing that buries the one proof that matters, and no human detail — a bio that could belong to anyone belongs to no one. Also common: leading with childhood or degrees when readers only care what you can do for them.
Lead with the reader-relevant result, keep the personal detail to one line, and update the bio every book — each new title is fresh proof. Your bio on the book description page and your book pages should always match.

The bio worksheet
Fill in the raw facts first — numbers, roles, names. The bio almost writes itself from good raw material.
1.I help [reader] [outcome]
Reader-relevant result first, always.
2.My one best proof
A number, role, or named outcome. Small and specific beats big and vague.
3.My book(s), if any
Each title is proof — list them.
4.One human detail
City, habit, opinion — one line that makes you a person.
5.Write the short bio (50–75 words)
Result + proof + book + human detail. Read it aloud.
6.Cut and expand
One-liner = first sentence only. Long = add backstory before the human detail.

Frequently asked questions
Third person for book pages, guest posts, and media (“Maya helps…”); first person for your own about page and social profiles (“I help…”). Keep both versions — they're one pronoun-swap apart.
