Social media copywriting: the basics for small businesses

Copywriting is writing with a job to do. On social media that job might be getting someone to stop scrolling, understand a tip, trust you a little more or take an action. Every word in a post counts: the caption, the text on the image or video, the first line of a script, your bio and even your replies.

It's different from writing a caption that sells. Selling is one job copy can do. Most of your posts have quieter jobs, like teaching, entertaining or showing who you are, and the same basics apply to all of them.

Social copy is also read fast. A post gets a moment in a busy feed, so it has to make sense straight away, without the reader scrolling back or opening a link.

• Captions: the text under or beside the post.
• On-image text: headlines and slide text on photos, graphics and carousels.
• Video scripts: what you say in the first seconds and the on-screen text.
• Profile copy: your bio, highlights and pinned posts.
• Replies and comments: often the copy people remember most.

Write to one person, not 'everyone who might be interested'. Picture a real customer: what they're worried about, what they want, and the words they use when they ask you about it. Use their words, not your industry's.

A quick way to find those words: read your last twenty customer messages, reviews and enquiry forms, and copy out the phrases people use to describe their problem. Those phrases make better hooks than anything you'll invent at a desk.

If your customers fall into very different groups, such as homeowners and landlords, write separate posts for each rather than one post that tries to speak to both.

1. Write one sentence about who the post is for: 'a first-time buyer who's nervous about hidden costs'.
2. Write one sentence about what you want them to think, feel or do after reading.
3. Write the post as if you were talking to that one person across the counter.

Clear writing isn't dumbed down. GOV.UK's content guidance cites research into legal documents in which 80% of people preferred sentences written in clear English, and the more educated and specialist the reader, the stronger that preference. The same guidance suggests splitting sentences over 25 words and keeping paragraphs to no more than five sentences.

• Put the point first. If someone reads only one line, it should be the useful one.
• Use short, common words: 'buy' not 'purchase', 'help' not 'assist'.
• Use the active voice: 'We fix your boiler the same day', not 'Same-day repairs are offered'.
• One idea per post. A second idea is a second post.
• Be specific: 'ready in 20 minutes' beats 'quick and easy'.
• Explain any jargon the first time, or leave it out.
• Cut filler words such as 'really', 'very', 'just' and 'in order to'.
• Use digits in hooks and on images, where people scan: '3 tips', not 'three tips'.
• Break long captions into short paragraphs with a line between them.

Most good posts follow one of a handful of shapes. Pick the shape before you write and the words come faster.

• Mix structures through the month. A feed of nothing but lists feels like homework; a feed of nothing but stories hides what you sell.

Your brand voice is how your business sounds in writing. For a small business it's usually close to how the owner talks to customers on a good day. Write it down so posts sound the same whoever writes them.

For example, a hypothetical dog groomer might choose cheerful, practical and local. 'Muddy paws? We've got Saturday slots' fits that voice; 'We are pleased to offer weekend grooming appointments' doesn't.

1. Pick three words that describe how you want to sound, such as warm, direct and expert.
2. For each, write what it doesn't mean: warm but not gushing, direct but not blunt.
3. List words and phrases you always use, and ones you never use.
4. Decide the small things: emoji or not, 'we' or 'I', exclamation marks or not.
5. Rewrite two old posts in the new voice and keep them as examples.

The words people see first are rarely in the caption. They're on the image, the first slide or spoken in the first moments of a video, so write those first.

• Hooks: promise a specific payoff ('3 receipts you need to keep this year') rather than tease ('You won't believe this').
• On-image text: a few words, large enough to read on a phone, saying what the post is about.
• Carousel slides: one idea per slide, and the first slide's headline makes the promise the rest keeps.
• Video scripts: start with the payoff, not a greeting. Write the script the way you speak, then read it aloud and cut what you trip over.
• Bios: who you help, what you do, where, and the one action you want visitors to take.
• Pinned posts: a short 'start here' that tells new visitors what you do and what to do next.
• Replies: answer the actual question, use the person's name, and move private details to messages.

Most copy gets better by getting shorter. Here's a hypothetical first draft from an accountant, and the edit. The edit puts the reader's problem first, names the place and replaces 'a comprehensive range of bookkeeping solutions' with what the customer actually gets.

1. Read it aloud. Rewrite anything you wouldn't say to a customer.
2. Check the first line: does it make sense, and make someone want more, on its own?
3. Cut every word that doesn't change the meaning.
4. Check every claim is true and you could show evidence for it.
5. Check spelling, names, prices, dates and links.
6. Check the length against the platform's limit with a character counter.
7. Make sure there's one clear next step.
