Key Findings: Social Proof A/B Tests

Across 47 social proof experiments, 45% resulted in a statistically significant win. Winning variants saw an average lift of +15.9%. Meanwhile, 7 tests underperformed the control with an average drop of -10.6%.

19 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 social proof testing strategy and avoid repeating experiments that have already been run.
