How much traffic and time do you need to reach significance?

At ~5,000 daily visitors and a 3.00% baseline conversion rate, you'll need ~53,148 visitors per arm; at this traffic, gathering that sample is estimated to take about 43 days to detect a 10% relative lift. Reliable tests need enough observations; one month may be enough to run some tests but may not provide enough evidence for a confident conclusion. Up to three months can be a useful planning runway, not a required duration or a guarantee; Variantix's existing confidence and evidence checks determine when a result is ready.

Reliable tests need enough observations, and gathering them takes time. One month may be enough to run some tests but may not provide enough evidence for a confident conclusion; up to three months can be a useful runway when needed. This is planning guidance, not a required duration or a guarantee, and the existing confidence and evidence checks determine when a result is ready.
