In the pantheon of content types, the case study takes a special place. While blog posts and white papers are often for consumer education purposes, the case study is one of the best ways to shine a spotlight on your brand, services, differentiators and successes for any potential client.
It’s one of the more direct content marketing assets, and ideal for leads who are further down the funnel. The case study is used to explain exactly how you helped solve a problem for a client or customer, and thus tell your story and demonstrate your value or return on investment.

What Is a Marketing Case Study?
A marketing case study is a narrative of how your business met a need, solved a problem or helped in a project. They act almost like customer reviews in that the case study relays what the product or service is, how it was used and what the impact was through methods like qualitative research and interviews. Case studies are effective in both B2B and B2C marketing.
The ultimate takeaway for readers should be an understanding of your business and the benefits you can deliver – and there’s no better source of that material than real-world wins. To start on the case study writing process, begin by:
- Scouting for customer successes to share.
- Reaching out to previous or existing clients.
- Arranging a case study interview.
- Tailoring interview questions with credible sources.
- Identifying your target audience.
- Thinking about case study design concepts.
- Considering pairing other deliverables with relevant facts
- Devising a case study distribution strategy.
When you sit down to write a case study, it’s important to know the general format. While there’s no hard-and-fast case study template, a commonly used format is: overview, challenge/opportunity, solution, outcome:
- Overview : Paint the overall picture and explain what the scenario is, who is involved, what the parameters of a project were; provide any other needed contextual details.
- Challenge/opportunity : Outline the key business challenge, consumer problem or market opportunity.
- Solution : Talk about the product or service you provided and how you deployed tools or strategy.
- Outcome : Describe the positive impact of your product or service, whether it was an improved customer experience or client return on investment.
Best practices include quotes from customers, client contacts or internal staff wherever possible so the real-world use case resonates with the reader, including any new potential customer.
The end result should be a polished asset that answers any remaining questions that potential customers might have. And to give you some insight as to what that looks like, here are 7 B2B and B2C case study examples.
Aware is a leading global provider of software products and solutions for biometric identification and authentication — all of which may be difficult to understand in practical applications. But the company’s case study “The World’s Largest Employer Uses a Web-Based Platform for Biometric Identity Proofing” is a primary study analysis example of what to do right when writing case studies
This case study follows the generally recommended template of overview-problem-solution-outcome, and conveys Aware’s story in clear terms that expertly explain the product and benefits. Of course, having the world’s largest employer (the U.S. Department of Defense) as a case study subject lends credibility to Aware, which can explain how it succeeded on one of the highest levels, thereby creating a persuasive asset to be implemented into any scale of a marketing campaign.
Right off the bat, HubSpot lets readers know the main benefits with data. The title doesn’t mess around, basically pulling the conclusion all the way up. The case study itself follows closely along the overview-problem-solution-outcome format, creating a natural progression for the story and the reader to follow along with.
One of the best elements of this example is the case study design. The overview is set in a shaded box that draws the attention of the reader; functionally, this helps ensure they have context for what’s about to follow. From there, screenshots help add a visual touch that reinforces the product use case, and emphasis is added on tangible takeaways like “saving up to 50 hours each quarter on manual processes.”
Another cue to take from HubSpot is building up a library of case studies. Armed with, HubSpot can share sector-specific content that plays well with a target audience.
For an example from the B2C marketing world, we turn to Walmart Labs, a division of the retail multinational that incubates innovation. It also has quite a few handy case studies for how Walmart is using technology to drive better customer experiences and operational efficiency.
Its “Seamless Returns Experience” case study is a succinct examination of the issue at hand and what Walmart is doing to find a solution.
Something this case study does particularly well is highlight the most important takeaways. It makes for an easy read, but also a compelling case study. Readers come away with direct knowledge of what Walmart is doing to solve pain points in the returns process, and how successful its initiatives have been at making for a more streamlined experience for any prospective client.
You’ve likely heard of Software-as-a-Service, but have you heard of Finance-as-a-Service? After reading this case study from Consero, you’ll get a clear picture of exactly how outsourced finance and accounting can help businesses grow or seize opportunity. The table of contents helps set the stage for the journey and what readers should expect.
The art in Consero’s case study is the narrative it creates using quotes from a client contact. They help bring personality to the piece, as well as authority. The design of the case study makes ample use of pull quotes, which pump up the effect even further. Combined with the linear progression of overview-challenge-solution-outcome, the artful storytelling provides insights as well as evidence.
Sometimes the case study challenge doesn’t have to be financial or operational; it can also be an exploration of a company’s efforts to advocate sustainability, social responsibility and corporate governance.
That’s what Coca-Cola took the opportunity to do in producing this case study of the brand’s efforts to support and train workers in Brazil, as well as innovate solutions for underserved communities.
While this B2C marketing example is a bit more long form, the depth and knowledge it provides are key for the reader, whose understanding of the material is helped along by graphical elements. The technical explanations don’t come at the sacrifice of personality, however, as the stories of Brazilian youth are documented with quotes and anecdotes to help humanize the piece, which is, after all, a case study in how Coca-Cola is pursuing social and economic growth for foreign communities.
Well hey, look who made the list. If you’re looking for a sample case study to model a first draft off, this example can help provide the roadmap you need to get started.

Don’t be afraid to add emphasis to what plays well for you. You want readers to come away with an impression that your business is knowledgeable, has a track record of success and can deliver solutions that align with their personal pain points.
