I spent way too long on the UI side and not enough tying it back to the actual hypothesis.
Start by clarifying the goal: to test if increased sharing frequency causes higher revenue. Then propose UI changes that lower friction to sharing, define metrics for sharing and revenue, and design an A/B test with sharing frequency as the treatment and revenue as the outcome. Finally, discuss how to measure causality and potential confounders.
Pro tip: Focus on establishing causality, not just correlation. Suggest using an instrumental variable or a randomized encouragement design if direct manipulation of sharing is difficult.
Restate the goal: determine if more frequent sharing leads to higher revenue. Formulate a clear hypothesis, e.g., 'Increasing sharing frequency by X% will increase revenue by Y% through increased social exposure and purchases.'
Brainstorm UI changes that could increase sharing frequency, such as one-click share buttons, social proof prompts, or reminders. Prioritize changes that are easy to implement and likely to impact sharing behavior.
Select primary metrics: sharing frequency (e.g., shares per user per week) and revenue (e.g., average revenue per user). Design an A/B test where the treatment group sees the redesigned UI and the control group sees the current UI. Ensure randomization and sufficient sample size.
Compare sharing frequency and revenue between groups. Use statistical tests to determine if differences are significant. To infer causality, consider instrumental variables or mediation analysis to rule out confounders.
If the treatment increases both sharing and revenue, consider rolling out the redesign. If not, analyze why and iterate on the UI changes. Also, explore long-term effects and potential negative consequences.
