How to Write a Business Bio (5 Templates Included)
Here is how to write a business bio in four sentences: say who you help, say what you do for them, give one piece of proof, and end with what you want the reader to do next. That's the whole structure. Everything else — the tone, the length, the third-person question — is a variation on those four moves.
Most bios fail because they open with a job title instead of a person. "Award-winning full-service marketing professional with a passion for excellence" tells a reader nothing they can use. "I help independent shop owners get found on Google" tells them immediately whether to keep reading. This guide gives you the structure, word counts for every platform, and five fill-in-the-blank templates you can adapt in about ten minutes.
The four-part business bio formula
Every bio that works — website About page, LinkedIn summary, conference program, podcast intro — follows roughly the same skeleton:
- Who you are and who you serve. Name, role, and the specific audience. Not "businesses" — which businesses.
- What you actually do. The service or outcome, in words a non-expert understands.
- Proof. Years in the field, number of clients, a recognisable employer, a credential, a result you can stand behind.
- The next step. A link, an invitation, or one human detail that makes you memorable.
Write those four things in plain sentences first. Don't reach for adjectives yet. Once the skeleton is honest and specific, polish is a ten-minute job.
How long should a business bio be?
There is no single correct length — there is a correct length per placement. Write one long version, then cut it down. Cutting is far easier than expanding.
| Placement | Target length | Notes |
|---|---|---|
| Instagram bio | 150 characters | Hard platform limit. Every character counts. |
| X (Twitter) bio | 160 characters | Hard limit, including spaces and emoji. |
| Email signature / directory listing | 25–50 words | One sentence, maybe two. |
| Short bio (guest post, speaker list) | 70–150 words | The most reusable version. Write this one first. |
| LinkedIn About section | 300–350 words | The field allows 2,600 characters, but roughly 1,800–2,200 is the practical sweet spot. |
| Website About page | 300–500 words | Room for story, values, and a clear call to action. |
One detail people miss on LinkedIn: only about the first 300 characters show before the "See more" link on desktop, and less than that on mobile. Treat those opening lines like a headline. If your hook is in paragraph three, most visitors will never reach it.
First person or third person?
Short answer: first person for anything you control, third person for anything someone else publishes.
Your own website, your LinkedIn About section, your newsletter footer — write those as "I" or "we". First person reads as a direct, confident claim and builds the familiarity that turns a visitor into an enquiry. Third person on your own site reads like a reference letter you wrote about yourself.
Switch to third person when your bio will sit alongside other people's in a uniform format: conference programs, book jackets, press releases, podcast show notes, or a team page where every profile matches. The organiser usually expects it, and a first-person bio in that context looks out of place.
Keep both versions in one document. You will need them at unpredictable moments, and rewriting from scratch under deadline is how weak bios get published.
Five business bio templates you can fill in
1. The short all-purpose bio (70–100 words)
"[Name] is a [role] who helps [specific audience] [achieve specific outcome]. Over the past [X] years, [he/she/they] has worked with [type of client or notable category], focusing on [your two or three core services]. [Name] is based in [city] and writes about [topic] at [site]. Outside of work, [one human detail]."
2. The website About page bio (first person, 250–400 words)
"I help [audience] [outcome]. Most of the people I work with come to me because [the problem they arrive with]. My approach is [one sentence on how you work — the method, not the adjectives]. Before starting [business], I [relevant background]. Since then I've [proof point]. If [reader's situation sounds familiar], here's how to get in touch."
3. The LinkedIn About section (first person, 300–350 words)
Open with the hook in the first 300 characters, then expand:
"[One-line statement of who you help and how.] I've spent [X] years doing [work] for [audience]. What I'm good at: [three to five bullets or a short list]. What I'm working on now: [current focus]. Get in touch: [email or link]."
4. The 150-character social bio
"[What you do] for [who]. [Location or niche]. [Link or call to action]."
Example shape: "Bookkeeping for trades businesses. 12 years, no jargon. Free 20-min call ↓"
5. The speaker or guest bio (third person, 100–150 words)
"[Full name] is [role] at [company], where [he/she/they] [what you do]. [Name]'s work focuses on [topic]. [He/She/They] has [credential, publication, or notable project]. [Name] speaks on [topics] and can be found at [site]."
Nine mistakes that make a bio forgettable
- Opening with a job title. Lead with the person you help, not the label you hold.
- Vague audience. "Businesses of all sizes" is the same as saying nobody.
- Adjective stacking. Passionate, dynamic, results-driven, innovative. Cut them all and see what's left. If nothing is left, that's the real problem.
- Unverifiable claims. Don't write numbers you can't back up. If a figure isn't checkable, describe the result qualitatively instead.
- Jargon a client wouldn't use. Write the way you'd explain your work to a friend over coffee.
- No proof at all. One concrete detail — years, clients served, a recognisable name — does more than three sentences of self-description.
- Burying the ask. Tell the reader what to do next. A bio without a next step wastes attention you already earned.
- Letting it go stale. An outdated bio quietly undermines you. Set a calendar reminder twice a year.
- Writing only one version. A single 400-word paragraph won't fit an Instagram field or a conference program.
How to write your bio in ten minutes
Open a blank document and answer these five prompts in one sentence each. Don't edit while you write.
- Who do I help, described as specifically as I honestly can?
- What problem do they have when they find me?
- What do I do about it?
- Why should someone believe I can?
- What should they do next?
Now delete every adjective. Read it out loud — if a sentence is hard to say, it's hard to read. Then cut it to your target length for the placement you need. That's your short bio. Expand it for LinkedIn and your About page later.
If your bio is going on a website you also want people to find, the words matter beyond the page itself. A clear, specific About page is one of the pages search engines use to understand what your business actually does — worth reading our plain-English guide to SEO alongside this.
Adapting your bio for different platforms
The core stays the same. What changes is emphasis:
| Platform | Emphasise | Tone |
|---|---|---|
| Website About page | Story, values, how you work | Warm, first person |
| Career track record, skills, current focus | Professional, first person | |
| Instagram / TikTok | Who you help, one clear next step | Direct, compressed |
| Speaker program | Credentials, topic expertise | Formal, third person |
| Guest post byline | Relevance to that article's topic | Neutral, third person |
| Email signature | What you do, how to reach you | One line |
A small habit worth building: when you land a guest post or podcast, rewrite the bio to match that audience rather than pasting the generic one. It takes two minutes and noticeably improves how many people click through.
Frequently asked questions
Should a business bio include personal details?
One is usually enough. A single human detail — a hobby, where you live, why you started — makes a bio memorable. Three or four turn it into a dating profile.
Can I use AI to write my bio?
It's a reasonable first draft tool, especially for reformatting a long bio into a short one. But AI doesn't know your specifics, and a generic bio is worse than a plain one. Feed it your real answers to the five prompts above, then edit heavily in your own voice.
How often should I update my bio?
Twice a year, plus any time your role, services, or main audience changes. Keep a master document with all versions so updating means editing one file, not hunting across eight platforms.
What if I'm just starting out and have no proof points?
Use what's true: relevant background, training, the specific problem you focus on, or why you started. Specificity substitutes for credentials better than most people expect. Avoid inventing experience — it's easy to check and expensive to lose trust over.
Does my bio affect how people find my business online?
Indirectly, yes. Clear, specific language about what you do and who you serve helps both readers and search engines. If you're building out your wider online presence, our guide to what digital marketing actually involves covers where a bio fits in the bigger picture.
The short version
Name the audience. Name the problem. Say what you do. Give one piece of proof. Point to the next step. Write it long, cut it short, keep every version in one file, and revisit it twice a year. That's a business bio that does its job.
