A lot of people over-think case studies and panic at the mere mention of them. I know this because as a freelance copywriter I’m forever gently nudging clients to collect case studies – a process that’s a lot like pulling teeth sometimes!

But a case study doesn’t need to be long — it just needs to explain the result that your product or service achieved for your customer. It can be as short as a paragraph or two, provided it checks all the boxes we’ll look at below. In fact, the shorter it is, the more people will read it. Who wants to sit down and read a 1000-word document about how great your business is?

I’m going to explain how to write a great case study quickly, and will include a simple template for gathering case studies where you can simply fill in the blanks and present to your customers.

But first…

What are case studies and why should you use them?

A case study is like a testimonial on steroids. It takes random client feedback that everyone uses as “testimonials” and puts it into a real world, relevant context.

They work because they allow customers to see first hand how your product or service specifically helped others in the same situation as they now find themselves.

The format for a case study should be a story. It should follow a structure of beginning, middle, and end. The “beginning” is the challenge facing your customer. The “middle” is the way you approached solving this problem or challenge. The “end” is the result experienced by the customer.

Where to use case studies

There are a few points to keep in mind when using case studies:

Terminology – Firstly, don’t call a case study a “case study”. Call it a “success story”. “Case study” sounds boring. Success story, on the other hand, promises not only a story, but a story about somebody’s success! We all love stories, and we all love success – especially when it’s success we too could be experiencing really soon (do you see where this is going?).

Placement – You should make your existing case studies as prominent as possible when making initial contact with prospects. This includes on important pages of your website and in any expression of interest marketing collateral such as a price list or brochure. I’m not a big fan of creating separate case studies. They’re best used when integrated with other material as supporting information rather than used in isolation.

Relevance – Ideally you’ll have more than one case study, so figure out the best place to use them. For example, if you offer three distinct services, include a success story about a particular service on the relevant service page of your website. Try not to lump them all in together (although there’s nothing wrong with also having a section on your website called “success stories” that repeats the information).

How to gather the raw information for the case study

There are three ways you can get the information you need to write a case study:

1. Phone – Calling your customer for a chat is going to yield great results. Make sure you use hands free so you can type notes, or better yet record the call so you can go over it later at your leisure. The great thing about a phone (or face to face) chat is that you can prompt them to go into more detail about certain points. Also, people are naturally more effusive verbally than they are when writing. Of course, explain you’re going to be using this information in a case study and make sure they’re okay with that before you start asking questions.

2. Email/Survey – This is not as good as using the phone, but if you can’t call your customers or have a lot of customers and simply want to ask them all for case studies (call it “feedback” though) then email will have to do. Use the questions outlined below, and when you’ve got the answers back, choose the ones you’ll be using and follow up to say thank you and ask if you can use the information in a case study for your business.

3. Video (advanced tactic) – this is where you film the customer answering the questions. Yep, this is the granddaddy of customer success stories. You’ll basically be making a mini documentary about your customer and how you helped them. Nothing beats that face to face connection of seeing and hearing the person talk about how you helped them achieve their desired outcome. You can then upload this video to Youtube (with the customer’s permission of course) and use it on your website, in the footer of emails, in pitches/presentations, online PDFs, and anywhere else you can think of. If you have the budget then hire a videographer to make this as professional as possible, or just record it on your phone or tablet, which will be much better than no video at all.

Questions to ask

This isn’t set in stone, but this is the loose flow of questions you want to go take your customer through:

  1. What challenge were you facing when you went looking for [name of solution]?
  2. What made you choose [business name] to overcome this challenge?
  3. What concerns (if any) did you have about using a [general product/service name]?
  4. What was it like using [specific product/service name]? Describe the process.
  5. What was the outcome of using [specific product/business name]?
  6. What would you say to other people considering using [specific business/product name]?

You might not want to use all these questions if they don’t quite fit. It’ll depend on the nature of your product or service, but you want to be asking at least four of the above six above questions, and 1, 2, 4, and 5 are crucial for getting the whole picture.

Writing your case study

Once you’ve got the answers to the above questions, you want to put it all together in a narrative. It’s not going to work as well if you use a Q&A format because it takes away from the flow of the story, so this is where some creativity is required in putting it all together. You can use some creative license here, provided you capture the spirit of what the person was trying to say and don’t twist their intention. Remember, you’ll be getting their permission before publishing this so don’t worry too much about writing what they say word for word.

Another thing to consider is whether you want to make it first or third person. For example, first person would be from the customer’s perspective (“I found they were really easy to work with…”) and third person would be “Judy loved how easy ABC Widgets were to work with…”. I think first person is always stronger because it sounds like the praise is coming from the customer, not you. You might use third person for a more detailed case study and just include elements of the first person story.

Let’s look at a real world example for a client I’m working with now:

Here’s the raw data that the customer sent back to my client, a property investment and buyer’s advocacy firm, via email:

And here’s how we can weave this into a success story:

“They outperform the market every time…”

“As an experienced investor, I was looking for a way to get an advantage over the market. I found I was constantly competing against emotional buyers who were driving up prices. I needed to find an edge over the competition.

I chose [business name] because of their reputation. They have the runs on the board, which made the decision easy. My only concerns were whether the apartment we purchased would be renovated fast, and whether we’d be able to rent it out, given that there were several other investors in the same block. 

But not only did [business name] get a great return for me, they even managed the property for me! And the guys who manage the property are sharp, proactive, and treat my investment like it was their own.

I’ve now used [business name] three times, and they’ve outperformed the market for me every time.”

(I’ve just thrown this together hastily for the purpose of this article. I’ll probably edit this a couple of times before using it in the client’s marketing material.)

Points to keep in mind

Note the headline – you want to take the most impressive quote from your entire case study and use it as the headline to grab attention. Keep your customer in mind. In this case it’s property investors, so they’ll be most interested in a strong return on their investment.

Stick to the structure of the questions – use the original questions to guide you. The customer will often answer the questions out of order and add irrelevant information, so it’s up to you to do some fancy editing and just keep the good stuff, sticking to the original flow of questions as you go.

Include the customer’s concerns – you might be wondering “why add the negative concerns the person had?” It might seem counter-intuitive to do this, but it’s important to keep them in. Here’s why: it’s likely the reader has the exact same concerns, so acknowledging these objections and addressing them will help overcome them. It’s important to address your customer’s objections in any type of sales or marketing, not just ignore them and hope the’ll go away.

Come back with fresh eyes – as with any sort of writing or editing, it’s important that you come back to your case study a day or two later and just make sure it all makes sense and you haven’t left anything out. Better yet, show it to a friend or colleague for their feedback and ask them for any suggestions to make the story more compelling.

Add a photo and the person’s full name – You need to make the case study as real as possible. Anonymous success stories aren’t going to cut it, and neither will a last initial such as “John B.”. These look made up. So you need to at least add the person’s full name (and their company name/position if it’s B2B – suburb or city if it’s B2C). It can be weird asking, but also try to get a photo of the person to use with the case study. The worst that can happen is that they say no and you’ll be no worse off than you are now!

The bottom line on gathering and writing case studies

Case studies are a valuable and relatively cheap and easy way to convince customers that your product or service will work for them. These type of success stories should be part of your overall business story, and should be used strategically so that they’re relevant to the customer and used at the right stage of the buying cycle. Share your own case study tips and experiences in the comments section below!
