12 great case study examples (plus case study writing tips)

Case studies have been hailed as a highly effective tool for content marketing—especially for nurturing readers through the middle of the funnel (MOFU) and bottom of the funnel (BOFU).

This long-form content style is also becoming more common as more marketers discover its value. According to Hubspot’s 2021 State of Marketing report, more than 30% of marketers use case studies as a primary marketing media—up from 13% in 2020.

If you’re new to the world of case studies, we’ll be diving into what case studies are, why they’re important, and how to create your own. We’ll also highlight some compelling case study examples that you can learn from.

What is a case study?

A good case study highlights customer stories showing the following:

1. The problems the business faced before using a product or service
2. How the product or service proposed to solve the problems
3. The before and after of using a product or service
4. The measurable positive impact of the product or service on metrics such as click-through rate, website traffic, or sales

While case studies are most often product or service-focused, sometimes businesses use them to share their brand or founder story.

These types of case studies typically focus on organizational progress, such as how they grew their revenue or website traffic. One example is this Outfunnel case study on how the team saved over 80% of its time with user onboarding.

Why are case studies important?

They may not suit every business. But case studies are beneficial, for example, for helping SaaS brands reach future customers.

If they make sense for your industry, case studies should be an important part of your content marketing strategy for many reasons.

Three reasons you should incorporate them as soon as possible are:

1. To provide value to your audience: At its core, the best marketing doesn’t just drive sales; it serves its audience. Case studies are a brilliant way to teach your audience tips they can incorporate into their businesses. It can also serve as research for industry experts to quote.
2. To show off your expertise: A great case study is a perfect blend of data and storytelling. It showcases your expertise to your target audience, most likely dealing with similar issues. By telling a good story in your case studies, you’re essentially saying, “Look how we made everything better for X client—we can do that for you, too.”
3. As social proof: Because case studies are available to the public, they’re undeniable social proof—better than hard-to-believe testimonials with client initials. This makes them extra valuable as MOFU and BOFU content; they can drive sales at the click of a button.

Good to Know: Not sure how to use case studies? They work well as lead magnets, landing pages, repurposed blog posts, and, if you have the capacity, even video content!

How to write your own case study

How can you write engaging, effective case studies like the examples above? Here are six steps.

1. Identify a worthy case

Think of projects—either for yourself or for clients—that got outstanding results. Then, whittle it down to the cases that your target audience is most likely to relate to, perhaps because they experience the same problem or have the same goal as in the case.

2. Reflect on your chosen case

Once you’ve decided on the case you’ll start with, do some deeper reflection on the details. What was the project goal? What challenges did you encounter along the way? How did you overcome them to reach your goal?

3. Think about differentiation

Take the last step even further and think of anything you did differently than others might. Did you an experimental tactic or strategy or create a custom solution? If so, use those details to subtly show potential customers why they should be interested in what you have to offer.

4. Gather quotes

Next, get hard-hitting quotes from project stakeholders or clients. Having their thoughts on goals, project obstacles, the solutions provided, and the outcomes will make your description of the case more credible.

5. Draft your case study

Time to turn the details you’ve compiled into a case study draft. How? We’ll talk about the best format for case studies shortly.

6. Add visuals

Next, create visuals that will reinforce the main points of your case study. These could include:

• Charts or screenshots to show the change in metrics before and after the project
• An infographic to give a brief visual overview of the case
• Pictures of deliverables (e.g. a web design agency might show a picture of the new site it designed for a client)
• Product images such as screenshots from within your software that was used on the project

After any designated reviewers and approvers give their stamp of approval on the case study, it’s ready to be published and promoted!
