Prioritize Experiments: Product Metrics Basics for Growth Marketers

Stop guessing. Use activation and retention data to pick your next high-impact move.

Who This Helps

This is for growth marketers who are tired of running random tests and hoping something sticks. You want to move channel metrics like conversion or retention, but you need a clear way to decide which experiment to run next. The Product Metrics Basics course is built for exactly this—it gives you a repeatable system to focus on the moves that actually matter.

Mini Case

Meet Priya. She runs growth at a SaaS startup with 12,000 sign-ups last quarter. But only 18% of those users activated (completed the key action within 7 days). Her team had three experiment ideas: a new onboarding email, a feature tooltip, and a referral discount. Without a clear priority, they argued for weeks. After using the Product Metrics Basics framework, Priya checked her activation definition and retention data. She saw that users who completed step 3 of onboarding had 40% higher 7-day retention. She picked the onboarding email experiment. It lifted activation by 12% in two weeks.

Do This Now (5 Steps)

  1. Lock your activation definition. Write down one action and one time window. For example: "Complete the first report within 7 days." This stops definition drift.
  1. List your top 5 key events. Use the event taxonomy from the course. Each event needs a clear name and required properties (like source, plan type).
  1. Pick your North Star and two guardrails. Your North Star is the metric that says you're winning. Guardrails protect you from breaking the product (like keeping load time under 2 seconds).
  1. Cut one segment. Don't look at all users. Pick one segment—like free trial users who didn't activate—and see where they drop off. That's your experiment target.
  1. Run one experiment this week. Use the segment diagnosis to choose the highest-impact change. Measure against your activation and retention baselines.

Avoid These Traps

  • Using different definitions across teams. If marketing says "activated" is sign-up and product says it's a purchase, you'll never agree on priorities. Standardize with the activation definition card.
  • Tracking the same event three ways. One team calls it "sign-up," another calls it "register." That kills your data. Use the event taxonomy to enforce one name and property set.
  • Optimizing the wrong thing. Without guardrails, you might boost activation but crash retention. For example, a referral discount might bring in low-quality users who churn fast.
  • Looking at averages. Aggregated dashboards hide where the real problem is. Always cut by segment—like users from paid ads vs. organic—to find the leak.

Your Win by Friday

By Friday, you'll have a clear experiment priority backed by real numbers. You'll know exactly which channel move to make next—and why it's the highest-impact choice. No more guesswork, no more team debates. Just a focused test that moves your metrics. And hey, you might even free up an hour to grab coffee without checking dashboards every five minutes.

This system comes straight from the Product Metrics Basics course. It's designed for busy growth marketers who want results, not more meetings.
