Why it works
The case study earns its Clarity tag because the core before-state is not knowing what works: the team had ideas but no reliable way to test them without developer involvement or release cycles. The three specific test walkthroughs with hypotheses, rationale, and results are the strongest section, giving readers a replicable model rather than vague claims. The overall headline metric of 10% CTR lift is modest and the story leans more on process improvement than a dramatic outcome number, which limits its punch.
Steal this
Publishing individual test hypotheses, rationale, and results as mini case studies within the case study gives readers a concrete, repeatable framework they can map to their own experimentation programs.
