Key takeaways
A social media bio for business has one job: to tell a visiting buyer in a few seconds that they are in the right place and what to do next. Four lines do it: what you do and for whom, where, one piece of proof, and one contact route.
- 4 lines: what and who, where, proof, and how to contact.
- Use the words buyers search for, not a slogan.
- 1 link, going to the most useful page for a new visitor.
- Review the bio every quarter and after any service change.

Chat on WhatsApp →Why does the bio matter so much?
The bio matters because it is where interested people go next. Someone who liked a post taps through to check who you are. If the bio answers their questions, they follow, message or click. If it does not, the post's work is lost.
What are the four lines?
Line one says what you do and for whom. Line two says where you work. Line three gives one piece of proof, such as years trading, a rating or an accreditation. Line four gives one way to get in touch. Everything else is optional.
- 'Kitchen and bathroom fitting for homeowners.'
- 'Reading, Wokingham and Bracknell.'
- 'Rated 4.9 from 210 Google reviews.'
- 'Message us a photo for a quote.'
How does the bio differ by platform?
The four lines stay the same and the space changes. Instagram and TikTok give a short bio and one link. Facebook has separate fields for services, hours and area. LinkedIn company pages have a tagline and a longer description, which should open with the same plain sentence.
- Instagram and TikTok: four short lines and one link.
- Facebook: fill in category, services, area and hours.
- LinkedIn: plain tagline, then two paragraphs.
- All: the same name, logo and contact details.

Chat on WhatsApp →Which words should the bio include?
Include the words a buyer would type into a search box: the service and the place. Platforms use profile text to decide which accounts to show in search results. 'Emergency plumber in Leeds' can be found. 'Making homes happy since 2009' cannot.
What should you remove?
Remove slogans, lists of adjectives, strings of emoji used as bullet points, several competing links and anything out of date. Remove hashtags unless one is a real branded tag. Each of these takes space from information a buyer needs.
- Slogans and mission statements.
- 'Passionate', 'bespoke', 'solutions'.
- Old offers and expired dates.
- A link tree with ten options.
Are there details you are required to show?
A social profile is not a website, but if you sell through it, UK rules on business information still apply. Companies should make their registered name and details available, and traders selling to consumers online must identify themselves. Link to a page that carries the full details.
What does this look like in practice?
A pattern we see with UK small businesses: the bio was written the day the account was opened and never revisited. Services have changed, the area has grown and the link goes to a page that no longer exists. Ten minutes fixes it.
Bio checklist
Check every profile you run.
- States the service and the customer.
- States the area.
- Includes one piece of proof.
- Gives one contact route.
- The link works and goes somewhere useful.
- Name, logo and details match on every platform.
Next step
Open your main profile on a phone and read the bio as a stranger. Rewrite it in four lines before you publish another post.

Frequently asked questions
What should a business put in its social media bio?
Four things: what you do and for whom, the area you serve, one piece of proof such as a review rating, and one way to contact you. Use the plain words a buyer would search for. Write it for a stranger, not for yourself.
Should I put keywords in my bio?
Yes, naturally. The service and the place are the keywords that matter, because platforms use profile text for search. Write them as a sentence, not a list. Check by searching the platform for your service and town to see whether your profile appears.
How many links should a business bio have?
One primary link is best, pointing to the page most useful to a new visitor, such as a booking or services page. A menu of many links makes people choose and many will not. If you need several, list them on one simple page of your own website.
How often should I update my bio?
Check it every quarter and whenever services, area, opening hours or contact details change. An outdated bio is one of the most common reasons interested visitors leave without enquiring. Set a recurring reminder, because nobody remembers to check a bio that seems to be working.
