What should I expect from an A/B testing consultant?

An A/B testing consultant should help you set up testing infrastructure, prioritize what to test, design experiments, analyze results, and build testing culture. They should provide strategic guidance on testing strategy, not just run tests. Good consultants help you understand statistical significance, avoid common testing mistakes, and interpret results correctly. They should work with your team to build internal testing capability. Expect regular reporting on test results and business impact. A consultant should help you move from ad-hoc testing to a systematic experimentation program. Look for consultants who focus on business outcomes, not just running tests for testing's sake.
