Daily Prompt Pack: Growth Experiments – Ship and Test Tactics That Actually Move Metrics

Got a growth idea you want to test? These three prompts help you stress-test it before you ship. One for spotting the highest-use experiment, one for building the experiment brief, and one for auditing an existing funnel. Lets go.

Given this growth goal [GOAL] and our current metrics [KEY METRICS], list the 5 highest-impact experiments ranked by potential ROI. For each, state the hypothesis, required traffic, estimated lift, and what would make it not worth running. Output as a ranked table.

Design a structured A/B test brief for this experiment: [ONE SENTENCE EXPERIMENT DESCRIPTION]. Include: problem statement, control variant, treatment variant, primary metric, sample size needed (at 80% power, 5% significance), run time estimate, and the one thing that would make this test inconclusive. Format as a clean markdown doc.

[Cursor]

Audit this activation funnel: [PASTE FUNNEL STAGES AND DROP-OFF RATES]. Identify the single biggest untapped lever, propose a targeted growth experiment to address it, and outline the exact success metric and minimum detectable effect size. Keep the experiment scoped to a two-week sprint.
