Write a Website Case Study Without Inventing Results

“We transformed the business” sounds impressive but tells a prospective customer little about the work. A useful case study makes the project understandable and gives the reader evidence they can evaluate.

Start with a confirmed problem

Describe what the customer needed and which parts of the website were affected. Keep confidential details out of public copy. If the historical cause of a security issue is unknown, do not invent a vulnerability name to make the account sound more technical.

Show what changed

Explain the relevant actions, the scope and any constraints. Use authorised project material. Current website screenshots can show a present interface, but they are not historical before-and-after proof unless the original evidence exists.

• Confirm permission to identify the customer.
• Label demonstration screens and sample data.
• Record dates and conditions for measurements.
• Preserve the context of genuine customer feedback.
• State what was not measured or remains outside scope.

Use an evidence-led structure

For a performance project, show the tested URL, device context, method and specific fixes. For a redesign, show the changed navigation or enquiry journey. Do not turn a visual improvement into a claimed revenue increase without the customer's reliable business data.

Give the reader a relevant next step

Link to the service that delivered the work and explain what a new project review would cover. The case study should help a buyer understand your approach, not guarantee that every website will achieve the same outcome. Clear limitations can make the evidence more credible.
