Every experiment should produce insights that inform your next optimization decision. A consistent evaluation process helps teams build stronger experimentation programs over time. Summary Go beyond simply declaring a winning variation. […]

How to Write Better A/B Testing Hypotheses

Key Takeaways: Strong A/B testing hypotheses begin with observed visitor behavior, not opinions. Every hypothesis should identify the problem, proposed change, expected outcome, and success metric. Heatmaps, session recordings, and analytics provide the evidence needed to build stronger experiments. Better hypotheses lead to more meaningful experiments and more valuable learning, regardless of the outcome. Summary […]

Why Most A/B Tests Fail Before They Begin

Key Takeaways: Great experiments begin with curiosity, not assumptions. Strong hypotheses are built from evidence and visitor behavior. Testing too many changes at once makes results difficult to interpret. Every experiment should teach you something, regardless of the outcome. Continuous learning creates stronger optimization programs than isolated tests. Summary Most A/B tests fail long before […]

What Should You A/B Test First?

Key Takeaways: The best experiments begin with opportunities rather than ideas. High-traffic, high-value pages often produce the biggest optimization wins. Visitor behavior provides critical evidence for prioritization. Every experiment should answer one specific question. Optimization success comes from consistently identifying and acting on meaningful opportunities. Summary Choosing what to test first is one of the […]
