How to Write a Case Study (That People Will Actually Want to Read)

How to Write a Case Study (That People Will Actually Want to Read)

So, you’ve done a great job for a client and now you want to shout about it.

You’ve seen other businesses post case studies on their websites and social media, and you’re thinking: “Maybe we should do one too?”

Excellent idea.

A good case study is more than just a pat on the back — it’s proof that you know what you’re doing. It shows potential customers what it’s like to work with you. And when it’s written properly, it can be one of the most persuasive bits of content you’ll ever put out.

But… how do you write a case study without it sounding like a school project? Or one of those cringe LinkedIn humblebrags?

Let me show you.

What is a Case Study (and Why Should You Bother)?

A case study is basically a success story — but written in a way that focuses on your client and the transformation you helped them achieve.

If you’ve ever wondered, “How do I write a case study that doesn’t sound full of waffle?” — the answer is: you tell a real story.

Not just what you did, but why it mattered. What problem did the client have? How were they feeling before they found you? What changed because of your work?

That’s what people want to know.

It’s not about you showing off. It’s about showing you get results — and that you genuinely care about the people you work with.

Three Essentials to Include

There are lots of ways to structure a case study, but if you’re aiming for something that’s clear, readable and not too long-winded, make sure it has these three things:

1. The problem – What was going wrong? What was frustrating, broken, or not working?
2. The solution – What did you actually do? How did you help?
3. The outcome – What changed? How does the client feel now? Any stats or quotes you can share?

You don’t need to get fancy. The best case studies are the ones that sound like a real person wrote them — not like a robot’s had a go at writing a press release.

A Simple Case Study Template You Can Steal

Here’s a quick structure you can follow. This is what I often use as a case study writer, especially for small businesses who want to sound human (but still professional):

1. Headline
   Short, punchy and focused on the result.
2. Introduction
   One or two lines giving a bit of context. Who’s the client? What do they do?
3. The challenge
   Describe the problem in their words, if you can. Keep it relatable — no one likes jargon.
4. What we did
   Talk about your process. Not a full step-by-step breakdown, but just enough to show your thinking and approach.
5. The results
   Include outcomes — and if you’ve got numbers or direct feedback, even better.
6. Quote from the client
   Ask: “What would you say to someone else thinking of working with us?”
7. Wrap-up / Call to action
   “Looking for similar results? Drop us a message.”

As a case study copywriter, I can tell you the best ones are always:

• Easy to read (no waffle, no buzzwords, no ten-line paragraphs)
• Focused on the client (not just a “look how great we are” brag)
• Packed with real, specific detail

Bonus points if you include a photo, a quote from the client, or a visual showing the results.

Do You Need a Case Study Writer?

Look, I know you’re probably capable of writing your own case studies. But if you’ve been meaning to do one for the last six months and it’s still not written, it might be worth getting someone else to do it.

As a professional case study writer, I take care of the whole thing. I’ll interview your client (so you don’t have to chase awkward feedback), write it up in your tone of voice, and make sure the end result feels like it actually came from you — not from a marketing textbook.

I’ve written case studies for electricians, tech companies, graphic designers, training providers, you name it. If you’re a small business who wants to show what you’re capable of (without sounding like a corporate robot), I’m your woman.
