A/B testing involves showing different versions of a webpage or design to users and measuring which performs better. The benefits are understanding user preferences, optimizing websites by removing unnecessary features, and continually testing to find root causes. To conduct a test, run it long enough, ensure visitors see the same variation everywhere, and do multiple tests over different time periods.
