FAQ

When will I see the first results?+

We implement the first 'quick wins' after a one-week audit. Complex A/B tests require 2-4 weeks to reach statistical significance.

Do I need high traffic for CRO?+

Classic A/B tests require around 10k visits per month. Below this threshold, we rely on heuristics and sequential testing.
