SEO Experimentation & Optimization Science

SEO experimentation applies scientific methods to test changes before full rollout. It reduces risk, provides evidence for decisions, and enables continuous optimization based on data rather than opinion.

The experimentation process follows a cyclical hypothesis-to-decision loop.
