What is a case study?
Case study is a structured description of a real campaign or project. A good case study explains the starting point, the challenge, the actions taken, the limitations, the result, and the lessons that followed.
It is not a decorative success story. It is a decision-support material that helps the reader understand how a solution worked in practice and when it is truly relevant.
Why does case study matter in media sales?
For a prospect, case study is one of the strongest ways to assess a partner. It turns claims like “we have strong data” or “we know retail media” into a concrete example of what was done and what happened because of it.
In Listonic Ads, that matters even more because much of the offer value comes from the connection between app usage, shopping lists, mobile behavior, and shopper context. A good case study should unpack that honestly rather than just celebrating one metric.
How does case study work in practice?
The best case studies answer a few simple questions: what was the goal, who was targeted, what was deployed, why that route was chosen, what result came out of it, and what the project taught the team. Strong materials also describe constraints instead of hiding them.
That context is what separates a useful case study from a slide containing one attractive number without explanation. For that reason, case studies should stay consistent with a good campaign summary and often grow out of a well-designed test campaign.
How should case study quality be judged?
Case study is not a campaign KPI by itself, but it should be based on credible data and on a clear connection between the goal and the outcome. From a commercial perspective, the material should also help the client imagine a realistic cooperation scenario rather than only creating a nice impression.
The best case studies are concrete, fair, and decision-useful.
A strong case study should show:
- what the starting point and client problem were,
- which solution was used and why,
- what result was achieved and how it was measured,
- which constraints and learnings matter for future campaigns.
Common misunderstandings
- A case study should not be a glossy brochure with no constraints or context.
- One metric never replaces the explanation of the problem and the solution.
- A good case study should help the reader decide, not only be impressed.
