A case study is most persuasive when it helps a reader recognize their own situation. “We built a beautiful website” says little. Explain the starting problem, the decisions made, and what changed.
Include the useful detail
Describe the audience, constraints, old workflow, scope, trade-offs, and the result. Screenshots are helpful, but context is what lets a reader judge relevance. If numbers are private, use a specific qualitative outcome rather than inventing precision.
Keep it honest
Say what the project did not solve and what happened after launch. Permission matters when publishing customer names, images, or data.
Clear proof strengthens a website project more than generic praise does.
