The Post-Attribution Playbook for Growth — Eric Seufert, Mobile Dev Memo
from Sub Club by RevenueCat · host David Barnard, Jacob Eiting
On the podcast I talk with Eric about how measurement dysfunction paralyzes growth, why diversifying channels for the sake of diversification actually hurts performance, and the futility of trying to interpret why ads win.Top Takeaways: 📊 Broken measurement kills growthThe biggest pitfall isn’t creative or channel choice—it’s disorganized measurement. When finance, product, and UA each use different models, growth stalls. The fix isn’t another dashboard; it’s alignment. Build one coherent, incrementality-aware framework everyone trusts, with clear definitions of success and outputs that meet each team’s needs.🌊 Don’t diversify just to diversifySpreading budget across more channels feels safer but often reduces performance after integration, creative, and reporting overhead. Start with a waterfall method: max out your primary channel until ROAS hits your threshold, then move to the next. Diversify for scale or cross-channel effects—not optics.🎲 Stop asking why an ad workedWinners often defy tidy explanations. Treat individual ad outcomes as stochastic and largely uninterpretable. Put your energy into the system: feed diverse concepts, automate prospecting/synthesis, and measure whether your process is increasing the rate of wins over time. Learn from inputs and process—not post-hoc stories about outputs.⚡ Ship speed over certainty earlyYou won’t have fully baked LTV or incrementality in week one. Push spend methodically: kill obvious losers immediately, let plausible winners age, track cohort ROAS at day-7/30/60, and widen budgets as curves support it. Iterative frontier-pushing beats premature “terminal LTV” guesswork.🧩 Engineer better signalsAlgorithms optimize to the signals you send. Create intentional, high-intent events (light “hurdles” that correlate with LTV) and send those back to platforms. Better signals shift spend toward durable users and compound efficiency, especially as automation on major platforms accelerates.About Eric Seufert: 👨💻 Quantitative marketer, media strategist, investor, and author.📈 Eric shares expert advice on the Mobile Dev Memo blog and is an investor at Heracles Capital.💡 “The way I approach creative testing is trying to identify losers as quickly as possible.
