Prioritize Experiments: Product Metrics Basics for Growth

Stop guessing which experiment to run. Focus on the move that actually moves your channel metrics.

Who This Helps

You're a growth marketer who wants to move channel metrics without guesswork. You have a list of experiments, but you're not sure which one to run first. This is for you.

Mini Case

Meet Priya. She's a growth marketer at a SaaS company. Her team has 12 experiments on the backlog. She picks one that looks promising: a new onboarding email. After 7 days, the activation rate drops by 3%. Ouch. Priya realizes she didn't check her North Star metric or guardrails first. She needed a clear way to prioritize.

Do This Now (5 Steps)

  1. Define your activation event. Pick one action and one time window. For example, "complete setup within 7 days." This is your activation definition card.
  1. Create a minimal event taxonomy. List only 5 key events your team tracks. Each event needs required properties. No more, no less.
  1. Choose a North Star and 2 guardrails. Your North Star is the metric that matters most. Guardrails keep you from breaking the product. Write them down in a metrics charter.
  1. Cut your data by one segment. Look at activation broken down by user source. Find where it breaks. For example, "users from ads have 12% lower activation than organic."
  1. Pick the experiment that fixes that break. That's your highest-impact move. Run it next.

Avoid These Traps

  • Don't define activation differently across teams. One event, one window. Stick to it.
  • Don't track the same action three ways. Use your event taxonomy to keep everyone honest.
  • Don't optimize for the wrong thing. Your North Star keeps you focused. Guardrails keep you safe.
  • Don't look at aggregated dashboards. Segment your data. Find where the leak is.

Your Win by Friday

By Friday, you'll have a prioritized experiment that directly improves your channel metrics. No more guesswork. Just a clear next move. And maybe a little more sleep.

Fun fact: Priya now runs experiments with confidence. Her team calls her "the metric whisperer." Not bad for a week's work.
