Prioritize Experiments: Product Metrics Basics for Growth Marketers

Stop guessing which experiment to run. Use activation metrics to pick the highest-impact move.

Who This Helps

This is for growth marketers who are tired of running experiments that don't move the needle. You have a list of ideas, but no clear way to pick the winner. The Product Metrics Basics course gives you a simple system to prioritize.

Mini Case

Meet Priya. She's a growth marketer at a SaaS startup. Her team has 12 experiment ideas for next month. She uses activation metrics from the course to rank them. The top idea: simplify the sign-up flow. It targets a 40% drop-off in the first 7 days. That experiment alone could boost activation by 15%. She runs it, and activation jumps from 22% to 37% in two weeks. No guesswork.

Do This Now (5 Steps)

  1. Define your activation event. Pick one action a new user must take within 7 days. For Priya, it was "complete onboarding."
  1. Set a time window. Activation happens in a specific period. Use 7 days, not 30. Shorter windows give faster feedback.
  1. List your experiment ideas. Write down every test you're considering. Include the expected impact on activation.
  1. Score each idea. Give each experiment a score from 1 to 5 for potential impact and ease of implementation. Multiply them. Higher score = higher priority.
  1. Pick the top score. Run that experiment first. Track activation before and after. If it works, you just moved a key metric.

Avoid These Traps

  • Don't optimize for vanity metrics. Page views don't equal activation. Focus on the one action that matters.
  • Don't use a 30-day window. Too long. You'll wait forever to see if your experiment worked.
  • Don't run 5 experiments at once. You won't know which one caused the change. Test one at a time.
  • Don't ignore guardrails. If your experiment hurts retention, it's not a win. Keep an eye on the big picture.

Your Win by Friday

By Friday, you'll have a prioritized list of experiments based on activation metrics. You'll know exactly which test to run next. No more debate. No more wasted effort. Just a clear path to move your channel metrics.

And hey, you might even have time to grab coffee before the next stand-up.
