Questions
About the Conversion Rate Calculator
Is the lift percentage points or relative?
Relative. Going from 600 to 800 conversions on the same traffic is a 33% lift, which takes a 2.4% conversion rate to 3.2%.
Can I share the calculator with my team or a client?
Yes. The Room keeps the calculator live: anyone with the link can change the numbers and see the result update, with the method and assumptions on the same page.
