How do you choose sample size for Ab test?

To A/B test a sample of your list, you need to have a decently large list size — at least 1,000 contacts. If you have fewer than that in your list, the proportion of your list that you need to A/B test to get statistically significant results gets larger and larger.

Who does the A B testing?

Today, companies like Microsoft and Google each conduct over 10,000 A/B tests annually. Many companies now use the "designed experiment" approach to making marketing decisions, with the expectation that relevant sample results can improve positive conversion results.

How many users do you need for a B testing?

With between 10,000 and 100,000 visitors a month, AB testing can be a real challenge, as an improvement in conversion rate of at least 9% is needed to be reliable.
