How to write an X bio that gets followers (with examples)

Write an X (Twitter) bio that turns profile visits into follows: a simple formula, bio examples by niche, and the mistakes that make people leave.

What your bio has to do

Someone just read one of your posts or replies and tapped your name. They will spend a few seconds on your profile and decide whether to follow. Your bio has to answer one question in that time: what will I get if I follow this person?

X gives you 160 characters. That is enough for two short lines, and two lines is all you need.

A simple formula

Most bios that convert well follow the same pattern:

What you post about, for whom, in words your audience uses. "Posts on pricing and growth for SaaS founders."
Why you are credible, in one specific detail. "Took a bootstrapped tool from 0 to profitable." "Nurse for 12 years." "Shipping iOS apps since 2015."
Optional: one human touch or what you are working on now. "Building a bike-sharing app in Lyon."

Write it, then test it on a stranger: if they read only your bio, could they guess what your last ten posts were about?

Bio examples by niche

These examples are invented to show the formula. Make yours specific to you.

Founder: "Building a scheduling tool for clinics. Writing about what works (and what doesn't) on the way to €1M ARR."
Developer: "Backend engineer. I post practical Postgres and Go tips you can use today. 10 years of on-call so you don't have to."
Designer: "Product designer at a fintech. Daily breakdowns of good and bad UI, with fixes."
Marketer: "I grow B2B newsletters. Sharing every experiment, numbers included."
Writer: "Ghostwriter for tech founders. Threads on writing clearly and getting read."
Creator in fitness: "Strength coach. Simple programs for busy people over 35. No supplements to sell."
Student: "CS student learning ML in public. Notes, projects and mistakes, weekly."

The rest of the profile matters as much

Your bio sits among other elements that all shape the decision:

Display name: your name, optionally with a few words of context. Avoid long strings of emoji.
Photo: a clear face photo for personal accounts, consistent across platforms.
Banner: a chance to restate your promise in big words or show your work.
Pinned post: your best post on your main topic, as proof of what the bio says.
Link: one destination, the place you want followers to go next.
Location: optional, but useful if your work is local or you want to meet people nearby.

Bio mistakes that cost follows

A list of titles. "CEO | Investor | Speaker | Dad | Coffee lover" says who you are but not what you post.
Vague promises. "Helping people live their best life" fits a million accounts.
Inside jokes. Clever lines only your friends understand.
A bio that does not match the posts. Promising startup advice while posting football takes loses the visitor.
Hashtags and handles everywhere. One mention of your company is fine; a wall of tags reads as spam.
Never updating it. Revisit your bio when your focus changes.

Test and improve

Your analytics show profile visits and follows. If replies and posts send plenty of visits but few follows, the profile is the bottleneck. Change one thing at a time, the bio, then the pinned post, then the banner, and compare follows per profile visit over a couple of weeks each.

A strong bio multiplies everything else you do, especially replies: our X reply strategy guide covers how to write replies that send the right people to your profile in the first place.

Frequently asked questions

How long can an X bio be?

160 characters. Two short lines that say what you post about and why you are credible usually work best.

What should I put in my X bio?

What you post about and for whom, one specific detail that shows why people should listen to you, and optionally what you are working on now. Add one link to where you want followers to go next.

Should I use emoji in my X bio?

Sparingly. One or two can add personality or break up the line, but a row of emoji takes space away from the words that tell people what you post.

Should I put hashtags in my bio?

Usually not. They rarely help people find you and make the bio harder to read. Use the plain words your audience would search for instead.
