The problem with CROtesting isn't the tools. It's the discipline. Most programs run tests with insufficient power, unclear hypotheses, and premature conclusions.
The discipline
- →Minimum sample size calculated before launch
- →Clear hypothesis tied to a specific conversion step
- →Run for full business cycles (minimum 2 weeks)
- →Statistical significance at 95% confidence
- →Test one variable at a time for unambiguous attribution
Programs following this discipline see 30-40% of tests produce significant winners. Programs without it see 5-10% and waste most of their testing capacity.
