The most common place people get stuck in a/b testing is proper design of experiments, i.e. absolutely no methodology (i.e. proper blocking) at all. It's ridiculous how a/b testing is perpetuated to be of paramount importance. A/B testing would be one of the last things I would do, if I worked at a small ecommerce company, for example. What lead to the current state is venture-backed companies and "growth hackers" and "conversion optimization experts" selling false promises to people who haven't read a marketing textbook in their life.
