A useful case study explains a real problem, the work completed and what can be verified afterward. It gives prospective customers something concrete to evaluate. You do not need dramatic revenue claims to describe a project well.
Choose a project you can discuss accurately
Start with work for which you have permission to share the relevant information. Confirm the client name, images, scope and any restrictions. Some projects are better described anonymously, and some should remain private.
For an Oakland County service business, the useful detail may be how a confusing service menu became easier to navigate or how a contact process was simplified. Do not add a city merely to target a search if the project has no genuine connection to that location.
Separate the problem, work and outcome
These three parts often get blurred. “The business needed more enquiries” describes a goal. “We reorganized the service pages and rebuilt the contact form” describes work. “The form passed a submission test” describes a verified result. None of those statements alone proves that revenue increased.
Use that distinction throughout the case study. It keeps the story understandable and prevents a design improvement from becoming an unsupported marketing claim.
- Context: What type of business and website was involved?
- Problem: What specific difficulty prompted the project?
- Scope: What did your team actually deliver?
- Decision: Why was that approach chosen?
- Evidence: What can a reader inspect or verify?
- Limit: What was outside the project or measurement?
Use screenshots with an explanation
A screenshot alone may show style without explaining the work. Add a caption that identifies the relevant change. If you show a before-and-after comparison, use comparable views and make sure the older image accurately represents the earlier state.
Avoid publishing private form submissions, analytics identifiers or customer information. Crop or redact sensitive details before sharing any image. The case study should help a future customer evaluate your work without compromising the previous customer.
Make numbers accountable
If you include a measurement, state what it measures, the period and the source. Distinguish a percentage increase from an absolute change, and explain relevant limitations. A seasonal difference or a new advertising campaign can affect results alongside a website update.
When you do not have reliable outcome data, say what was delivered and tested. Clear evidence of execution is useful. Inventing a conversion lift or calling every project a transformation weakens the value of the portfolio.
Connect the example to a customer decision
A Birmingham shop comparing designers may want to see how products are organized. A Bloomfield Hills service provider may care about explaining several offerings clearly. Help readers understand which aspect of the example applies to their situation, without implying that their results will be identical.
Link the case study to the relevant service and give readers a practical next step. Asking them to share their current website and the problem they want to solve makes the conversation more specific.
Google’s helpful content guidance emphasizes original information and evidence of experience. A factual project account can provide both while remaining useful to a human reader.
