If you want to learn how to write a case study that engages prospective clients, demonstrates that you can solve real business problems, and showcases the results you deliver, this guide will help.
We’ll give you a proven template to follow, show you how to conduct an engaging interview, and give you several examples and tips for best practices.
Let’s start with the basics.
A business case study is simply a story about how you successfully delivered a solution to your client.
Case studies start with background information about the customer, describe problems they were facing, present the solutions you developed, and explain how those solutions positively impacted the customer’s business.
Absolutely. A well-written case study puts prospective clients into the shoes of your paying clients, encouraging them to engage with you. Plus, they:
Case studies serve your clients too. For example, they can generate positive publicity and highlight the accomplishments of line staff to the management team. Your company might even throw in a new product/service discount, or a gift as an added bonus.
But don’t just take my word for it. Let’s look at a few statistics and success stories:
In the B2B setting, events help generate the most leads, while case studies help convert and accelerate the most leads. (…) In a survey of B2B marketers, they listed case studies as their 3rd best way to nurture leads.
49% of B2B buyers said they now rely more on content to research and make purchase decisions.

Before we get into the nuts and bolts of how to write a case study, let’s go over a few examples of what an excellent one looks like.
The five case studies listed below are well-written, well-designed, and incorporate a time-tested structure.
This case study example from Lane Terralever incorporates images to support the content and effectively uses subheadings to make the piece scannable.
This case study from WalkMe Mobile leads with an engaging headline and the three most important results the client was able to generate.
In the first paragraph, the writer expands the list of accomplishments encouraging readers to learn more.
This is an example of a well-designed printable case study. The client, specific problem, and solution are called out in the left column and summarized succinctly.
This long format case study (6 pages) from Brain Traffic summarizes the challenges, solutions, and results prominently in the left column. It uses testimonials and headshots of the case study participants very effectively.
This case study from Adobe and Home Depot is a great example of combining video, attention-getting graphics, and long form writing. It also uses testimonials and headshots well.
Now that we’ve gone over the basics and showed a few great case study examples you can use as inspiration, let’s roll up our sleeves and get to work.
Let’s break down the structure of a compelling case study:
In this guide, we focus on written case studies. They’re affordable to create, and they have a proven track record. However, written case studies are just one of four case study formats to consider:
If you have the resources, video (like the Adobe and Home Depot example above) and podcast case studies can be very compelling. Hearing a client discuss in his or her own words how your company helped is an effective content marketing strategy
Infographic case studies are usually one-page images that summarize the challenge, proposed solution, and results. They tend to work well on social media.
The success story structure we’re using incorporates a “narrative” or “story arc” designed to suck readers in and captivate their interest.
Note: I recommend creating a blog post or landing page on your website that includes the text from your case study, along with a downloadable PDF. Doing so helps people find your content when they perform Google and other web searches.
There are a few simple SEO strategies that you can apply to your blog post that will optimize your chances of being found. I’ll include those tips below.
The headline should capture your audience’s attention quickly. Include the most important result you achieved, the client’s name, and your company’s name. Create several examples, mull them over a bit, then pick the best one. And, yes, this means writing the headline is done at the very end.
SEO Tip: Let’s say your firm provided “video editing services” and you want to target this primary keyword. Include it, your company name, and your client’s name in the case study title.
This is a mini-narrative using an abbreviated version of the Challenge + Solution + Results model (3-4 short paragraphs). Write this after you complete the case study.
SEO Tip: Include your primary keyword in the first paragraph of the Executive Summary.
Introduce your client to the reader and create context for the story.
Vividly describe the situation and problems the customer was dealing with, before working with you.
SEO Tip: To rank on page one of Google for our target keyword, review the questions listed in the “People also ask” section at the top of Google’s search results. If you can include some of these questions and their answers into your case study, do so. Just make sure they fit with the flow of your narrative.
Explain the product or service your company provided, and spell out how it alleviated the client’s problems. Recap how the solution was delivered and implemented. Describe any training needed and the customer’s work effort.
Detail what you accomplished for the customer and the impact your product/service made. Objective, measurable results that resonate with your target audience are best.
Share how your client might work with your company in the future.
Clearly detail what you want the reader to do at the end of your case study.
Include a “press release-like” description of your client’s organization, with a link to their website. For your printable document, add an “About” section with your contact information.
And that’s it. That’s the basic structure of any good case study.
Now, let’s go over how to get the information you’ll use in your case study.
One of the best parts of creating a case study is talking with your client about the experience. This is a fun and productive way to learn what your company did well, and what it can improve on, directly from your customer’s perspective.
Here are some suggestions for conducting great case study interviews:
Your sales and marketing team should know which clients are vocal advocates willing to talk about their experiences. Your customer service and technical support teams should be able to contribute suggestions.
Clients who are experts with your product/service make solid case study candidates. If you sponsor an online community, look for product champions who post consistently and help others.
When selecting a candidate, think about customer stories that would appeal to your target audience. For example, let’s say your sales team is consistently bumping into prospects who are excited about your solution, but are slow to pull the trigger and do business with you.
In this instance, finding a client who felt the same way, but overcame their reluctance and contracted with you anyway, would be a compelling story to capture and share.
If you’ve ever seen an Oprah interview, you’ve seen a master who can get almost anyone to open up and talk. Part of the reason is that she and her team are disciplined about planning.
Before conducting a case study interview, talk to your own team about the following:
Pro Tip: Tee up your client. Send them the questions in advance.
Providing questions to clients before the interview helps them prepare, gather input from other colleagues if needed, and feel more comfortable because they know what to expect.
In a moment, I’ll give you an exhaustive list of interview questions. But don’t send them all. Instead, pare the list down to one or two questions in each section and personalize them for your customer.
Decide how you’ll conduct the interview. Will you call the client, use Skype or Facetime, or meet in person? Whatever mode you choose, plan the process in advance.
Make sure you record the conversation. It’s tough to lead an interview, listen to your contact’s responses, keep the conversation flowing, write notes, and capture all that the person is saying.
A recording will make it easier to write the client’s story later. It’s also useful for other departments in your company (management, sales, development, etc.) to hear real customer feedback.
Use open-ended questions that spur your contact to talk and share. Here are some real-life examples:
During the interview, use your contact’s responses to guide the conversation.
Once the interview is complete, it’s time to write your case study.
Case study writing is not nearly as difficult as many people make it out to be. And you don’t have to be Stephen King to do professional work. Here are a few tips:
Also, make sure to do the following:
The more you can use your contact’s words to describe the engagement, the better. Weave direct quotes throughout your narrative.
Strive to be conversational when you’re writing case studies, as if you’re talking to a peer.
Include images in your case study that visually represent the content and break up the text. Photos of the company, your contact, and other employees are ideal.
If you need to incorporate stock photos, here are three resources:

Make sure there are no grammar, spelling, or punctuation errors. If you need help, consider using a grammar checker tool like Grammarly.
My high school English teacher’s mantra was “tighten your writing.” She taught that impactful writing is concise and free of weak, unnecessary words. This takes effort and discipline, but will make your writing stronger.
Also, keep in mind that we live in an attention-diverted society. Before your audience will dive in and read each paragraph, they’ll first scan your work. Use subheadings to summarize information, convey meaning quickly, and pull the reader in.
Consider applying the following best practices to your case study:
After you have a final draft, send it to the client for review and approval. Incorporate any edits they suggest.
Use or modify the following “Consent to Publish” form to get the client’s written sign-off:
Consent to Publish

As we saw in the CurationSuite and Brain Traffic examples earlier, case studies get downloaded, printed, and shared. Prospects can and will judge your book by its cover.
So, make sure your printed case study is eye-catching and professionally designed. Hire a designer if necessary.
Case studies work because people trust them.
They’re not ads, they’re not press releases, and they’re not about how stellar your company is.
Plus, everyone likes spellbinding stories with a hero [your client], a conflict [challenges], and a riveting resolution [best solution and results].
After you’ve written your case study and received the client’s approval to use it, you’ll want to get it in front of as many eyes as possible.
Try the following:
If you want to stand out and you want to win business, case studies should be an integral part of your sales and marketing efforts.
Hopefully, this guide answered some of your questions and laid out a path that will make it faster and easier for your team to create professional, sales-generating content.
Now it’s time to take action and get started. Gather your staff, select a client, and ask a contact to participate. Plan your interview and lead an engaging conversation. Write up your client’s story, make them shine, and then share it.
Get better at the case study process by doing it more frequently. Challenge yourself to write at least one case study every two months.
As you do, you’ll be building a valuable repository of meaningful, powerful content. These success stories will serve your business in countless ways, and for years to come.
