Universal A/B testing patterns validated across multiple industries. These insights apply regardless of your vertical.
Across 275 cross-industry experiments, 15% resulted in a statistically significant win. Winning variants saw an average lift of +25.9%. Meanwhile, 5 tests underperformed the control with an average drop of -11.3%.
229 experiments were inconclusive, meaning the difference between control and variant was not statistically significant. Inconclusive results are still valuable — they tell you what doesn't move the needle, so you can focus testing effort elsewhere.
These results come from real A/B tests with sample sizes ranging from hundreds to millions of visitors. Use them to inform your own cross-industry testing strategy and avoid repeating experiments that have already been run.
