Key Findings: Checkout A/B Tests

Across 76 checkout experiments, 13% resulted in a statistically significant win. Winning variants saw an average lift of +21.3%. Meanwhile, 2 tests underperformed the control with an average drop of -5.3%.

64 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 checkout testing strategy and avoid repeating experiments that have already been run.
