How to write a bio for Instagram: 9 notes

To write a bio for Instagram, start from the words your clients already use about you, not from your own description of the business. Draft it about three times longer than the 150-character limit, outside the app. Then cut it down and check it where strangers actually read it.

What belongs in a business bio (the trade, the place, the next step) is covered in what a small business should put in its Instagram bio. This page is a set of field notes on the writing itself. There are nine, each tied to a place you can open today: your reviews, your inbox, the edit screen, your Insights.

Where do the words for an Instagram bio come from?

1. In your reviews. Open your last ten Google reviews and underline every phrase that describes what happened. Clients rarely write "holistic" or "bespoke". They write "back to running in three weeks", "the cake survived a two-hour drive", "replied on a Sunday". Each phrase names a situation and a result, which is exactly what a stranger scans a bio for. The line you are looking for is often already written, by someone who paid you.

2. On your website, between the About page and the testimonials. A small business website usually holds two vocabularies. The owner's pages describe the category and the values. The testimonials describe circumstances and outcomes. Anyone who builds software that extracts a brand's voice from a website runs into this split, and has to decide which vocabulary to trust for very short copy. The answer is mechanical. A client writes about one thing that happened to them, so every word carries a fact. An owner writes about everything the business does, so every word has to stay general. At 150 characters there is no room for general words. Put your About page next to your testimonials and compare the nouns; the split shows up in a minute. Keep the client phrases you find in a knowledge base your content tool actually reads, because your captions need the same vocabulary as your bio.

3. In your DM inbox. Scroll through the first message of your last twenty conversations with people who were not yet clients. One opening question usually comes back: do you deliver, are you taking new clients, how much is a session, where exactly are you. A question that keeps coming back is a sentence your bio is missing. Answer it there, in as few words as it takes.

How do you fit an Instagram bio into 150 characters?

4. In your notes app, before the edit screen. Writing straight into Instagram's bio field puts the character counter in charge. When you type against a limit, you pick the words that fit, and the short words that fit are the generic ones: handmade, quality, passionate. Write the first draft in your notes app at around 400 characters instead, with every review phrase and inbox answer that seems important. Then cut in order. Adjectives go first, because the review phrases already carry the proof. Category words go second, because your name field and your photos already say them. What remains is usually a client phrase and a next step. Which two ideas deserve the final characters is the last decision, and it is easier with real material on the page.

5. On the counter. A line break is a character. So is every space and every symbol. A bio stacked on five lines spends four characters on breaks, and a symbol at the start of each line spends at least five more. That is at least nine characters, about two words, spent on layout. One break is usually enough to separate what you do from what to do next.

6. On a business with two accounts. An @mention in the bio is a tappable link to another profile. If your business runs a second account, such as a shop, a studio or a sister venue, mentioning it gives visitors a second place to go without replacing the one external link the profile displays. It costs the length of the handle plus one character.

7. In a font generator. The stylized letters sold as "Instagram bio fonts" are not a font. They are mathematical symbols and other Unicode characters that happen to look like letters. A screen reader may read them out as symbols or skip them. A search for your plain trade word is a search for different characters, so it does not find them. What those characters break in captions applies to bios in the same way.

How do you know if your Instagram bio works?

8. In Insights, fourteen days later. A professional account shows profile visits and external link taps in the profile activity section of Insights. Divide taps by visits for the two weeks before you change the bio, then for the two weeks after. Change nothing else in that window: same link, same profile picture, same posting rhythm. There is no universal good ratio, only yours before and after. The name field above the bio can only be changed twice in 14 days, so settle the name first and run your tests on the bio.

9. In a translated view. Instagram can show a "See translation" link under a bio written in a language the reader's app does not use. A hotel or a restaurant that relies on foreign guests is read this way more often than its owner thinks. Puns, slang and abbreviations come out of machine translation as nonsense. A plain sentence with a noun and a number survives. If many of your bookings come from abroad, read your bio through the translation before you publish it. The guides for independent hotels pick up from there, on reviews, OTAs and direct bookings.

What should your posts do once the bio is live?

A bio written in client words sets an expectation that the grid below it has to keep. Once the line says "back to running in three weeks", the posts under it need to show runners, timelines and recoveries, not generic wellness quotes. The bio makes the promise once. Your posts repeat it every week, to an audience that arrives on a different day each time. That is the job of Instagram posts generated from your own website and brand: the same vocabulary, week after week, without you retyping it.

Start with note three. What is the first question strangers ask you, and why is the answer not on your profile yet?
