First A/B test: +18% sign-ups on a tiny change

Changed the sign-up button from “Get started” to “Try a free lesson” and ran it for two weeks. 18% more sign-ups, same drop-off later. Small team, small change, big smile.

Textbook: one change, a clear metric, and you checked the next step of the funnel too. Write down why you think it worked before you run the next one.

    Love that you checked drop-off. So many people stop at the first number.

    How many visitors per variant? Curious about the sample size.

    @Daniel about 3,100 each — I waited for the full two weeks before peeking.
