Your social media bio is the first thing potential customers read about your business. It's the two seconds where they decide whether to follow, visit your website, or keep scrolling.
The problem? Every platform has different character limits, different conventions, and different expectations. Writing one great bio is hard enough — writing eight is a full afternoon.
Why Your Bio Matters More Than You Think
When someone hears about your business through a referral, a Google search, or word of mouth, the first thing they do is look you up on social media. Your bio is what they see.
A good bio tells them:
- What you do (clearly, not cleverly)
- Where you are
- Why they should choose you
- How to take the next step
A bad bio? It's either empty, generic ("Welcome to our page!"), or hasn't been updated since 2019.
The Character Limit Problem
Each platform gives you a different amount of space:
| Platform | Character Limit | What Works |
|---|---|---|
| 150 | Punchy, location + key service + CTA | |
| Twitter / X | 160 | Concise, expertise-led |
| Bluesky | 256 | Room for personality |
| 255 | Service-focused, local keywords | |
| 2,000 | Professional, detailed, SEO-rich | |
| Google Business | 750 | SEO-optimized, all services listed |
| 500 | Discovery-focused, keyword-rich | |
| Threads | 150 | Conversational, personality-forward |
If TikTok is part of your mix, keep that bio especially tight; use the safe planning guidance in TikTok bio character limit 2026.
For a worked platform example, use the Instagram bio guide for businesses.
Writing every bio manually means rewriting and trimming and adjusting character by character. That's tedious, and most business owners give up after two platforms.
The Shortcut: Write One Bio, Then Cut It Down
The mistake is starting fresh on every platform. Write the longest version once and trim.
- Start from your own about page. It is already in your voice and already true.
- Write the LinkedIn-length version first — around 2,000 characters, everything you would want a customer to know.
- Cut to 750 for Google Business Profile: services, area, and how to reach you.
- Cut to 150 for Instagram: what you do, the city, one call to action.
Each cut is a decision about what matters most, which is a much easier task than a blank field.
Tips for Great Social Media Bios
Whichever platform you are writing for, here's what works:
Lead with what you do, not who you are
- No "Welcome to Johnson & Sons! Established 1987."
- Yes "Emergency plumbing in Phoenix — same-day service, no trip charges."
Include your location
Local businesses live and die by "[service] near me" searches. Put your city in your bio.
End with a call to action
Tell people what to do next: "Book online," "Call for a free estimate," "DM us for hours."
Match the platform's vibe
LinkedIn bios should sound professional. Instagram bios should be punchy. Twitter bios can be clever. Same message, different length and register.
Update it seasonally
Your bio from two years ago probably mentions services you've changed, hours you've updated, or a phone number that's different. Set a quarterly reminder to review.
Do this with AI
Bios take the Skill shape, because the job is one piece of writing you hand off once and reuse on every platform.
Give the AI your about page, your service descriptions, your city, and the one action you want people to take. Tell it which platforms you need and paste in the character limits from the table above. Our free Instagram bio generator is the fastest route, and the AI you already pay for is the other.
What comes back is one bio per platform, each cut to its limit, all in the same voice. Ask for the longest version first, so every short one is a trim of it.
Judge each one against the tips above. A bad result opens with a welcome or a founding year, leaves out the city, names a service you do not offer, or runs past the limit. Count the characters yourself before you paste. For the other jobs like this one, see the full list of marketing jobs you can hand to AI.
What to Do After Your Bios Are Set
Great bios get people to follow. Great content keeps them engaged.
If creating content consistently is the part you dread, Boomp prepares finished posts, carousels, and videos for your platforms and publishes what you approve. Plans start at $9/month, or $39/month with publishing. We read your website and ground every post in what it actually says, and by default nothing goes live without your review.
