Ship Yearly plan first

  • Current paywall converts more people, but Yearly plan first earns more per view. Buyers are choosing different plans, so judge the test on revenue, not conversion.

How much more each variant earns per view

Revenue uses prices after the 15% store fee. Bayesian model with a flat prior on conversion. Frequentist checks for reference: Yearly plan first: p = 0.074 on revenue, 0.028 on conversion. Traffic split check passed (p = 0.805). How this works

Why revenue per view and not conversion

Paywall tests usually change which plan people pick, not just whether they buy. Put the yearly plan first and fewer people may subscribe, but each of them pays seven times more up front. A calculator that only compares conversion rates would call that a loss.

This one counts purchases per plan, applies the store fee, and compares what each variant actually earns per person who saw it. The example above is that exact case: the current paywall converts better and still earns less. How the math works
