Full guide: definition, formula, and benchmarksWhy A/B Test Performance matters for PostHog users
PostHog's experimentation framework measures whether a variant wins on its target metric. But a variant that lifts signup conversion by 5% may simultaneously increase churn by 3%. Understanding the full impact requires connecting experiment results to your complete metric tree.
Mapping A/B test results into your metric tree reveals the cascading effects of each experiment across engagement, retention, and revenue. This ensures product decisions are based on holistic business impact, not isolated metric improvements.
