Judge every paywall and price test on revenue per user in the first 7 days

Chosen to shorten payback and fund more ad spend; worked well per guest

What they did

Used ARPU in the first 7 days (ARPU7D) as the single success metric for all monetization experiments, to optimize new revenue, shorten payback and support scaling user acquisition. Seven days covered the 3-day trial plus a few days, and was a default window available in RevenueCat charts. Also monitored ARPU7D of new cohorts in RevenueCat charts after rollouts.

What happened

Guest says it worked well as a tracker of new revenue.

How Mojo Increased ARPU 60% In Just Five Months – Michal Parizek, Mojo

David BarnardWhat was a key metric you were tracking during this? In setting up all these experiments, you're testing price, you're testing paywall layout, you're testing placements, do you have the monthly and annual? You're testing all these things. What was the unifying metric you were looking at to determine the success of those experiments?

Michal ParizekYeah, so our umbrella metric for all those monetization experiments was the average revenue per user in the first seven days. So this ARPU7D, 7 day, and yeah, we've intentionally used it because we, well, first of all we saw more potential in optimizing the new revenue rather than renewals, and just because that we wanted to shorten the payback period, we wanted to optimize the new revenue because of also supporting the user acquisition loop to allow higher spend, et cetera.

Michal ParizekSo we want to drive new revenue as we saw that we can actually scale that more, and we can actually compound that with the user acquisition and get more revenue in total. Yeah, so that's why we chose the early average revenue per user and specifically seven day because at that time we had three-day trial, so we wanted to have the window to be long enough to cover those three, four days. And I think it was just seven day. I think mainly because actually RevenueCat showed one of these ARPU pre-default is actually, that's actually maybe the first one is actually is what was available is seven day. So we choose ARPU seven day just I think because of that. And that actually, so they worked pretty well. Yeah, so basically we optimized for the new revenue, and as you probably know and everyone else in the app business, lots of new revenue is coming from the very early days, the very first few days. So it was a good metric for just tracking new revenue.

David BarnardDid you look back on some of those experiments and see the impact on retention? So did you knowingly sacrifice some long-term revenue for that quick return on ad spend?
