Key Findings: Form A/B Tests

Across 34 form experiments, 26% resulted in a statistically significant win. Meanwhile, 4 tests underperformed the control.

21 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 form testing strategy and avoid repeating experiments that have already been run.
