What is a Case Study? Examples for CRO, UX & SEO

In the world of website optimization—where Conversion Rate Optimization (CRO), User Experience (UX), and Search Engine Optimization (SEO) intersect—a case study is a structured narrative that documents how targeted changes impact real-world metrics. It outlines the initial challenges, the hypotheses formed, the methodology for testing (often leveraging tools like Prevue.me for actionable critiques on lead generation, performance, accessibility, and user flows), and the quantitative results achieved. By presenting before-and-after data points—such as conversion lift, improved page load times, or keyword ranking gains—a case study transforms raw analytics into compelling stories. These stories not only guide future optimization efforts but also serve as powerful marketing collateral to demonstrate expertise and build client trust. Well-crafted case studies connect strategy, execution, and results in a clear, replicable format that stakeholders across design, development, and executive teams can appreciate.
