Who This Helps
This is for growth marketers who are tired of running random A/B tests and hoping something sticks. You have a list of channel experiments, but you're not sure which one to run first. You want to move metrics without guesswork.
Mini Case
Meet Jenna. She manages growth for a SaaS company. She had 7 experiments lined up: a new Facebook ad creative, an email subject line tweak, a landing page redesign, a referral program update, a LinkedIn retargeting campaign, a blog content upgrade, and a pricing page test. She was overwhelmed.
Then she applied the Product Portfolio Strategy course's "Bet Sizing" mission. She ranked each experiment by two things: potential impact (how much it could move the needle) and confidence (how sure she was it would work). The landing page redesign scored high on impact (12% conversion lift expected) but low on confidence (only 30% sure). The email subject line tweak scored medium impact (3% lift) but high confidence (80% sure).
She chose the email tweak first. It took 3 days to set up, ran for 7 days, and delivered a 4% lift. Small win, but it freed up budget and attention for the bigger bet next quarter.
Do This Now (5 Steps)
- List your next 5 experiments. Write them down on paper or a doc. No filtering yet.
- Rate each on impact. Use a simple scale: 1 (low) to 5 (high). Ask yourself: "If this works, how much does it move my key metric?"
- Rate each on confidence. Again, 1 (low) to 5 (high). Be honest about what you know and don't know.
- Pick the one with the best combo. Look for high confidence first, then high impact. That's your next experiment.
- Run it for 7 days. Set a timer. No peeking at results early. Let the data speak.
Avoid These Traps
- Chasing the shiny object. Don't pick the experiment with the biggest potential impact if you have no clue how to execute it. Start with something you can actually run.
- Ignoring confidence. A 20% lift sounds amazing, but if you're only 10% sure it'll work, you're gambling. Confidence is your safety net.
- Overcomplicating the ranking. You don't need a spreadsheet with formulas. A simple 1-5 scale is enough to break the tie.
- Running too many at once. One experiment at a time. Otherwise you won't know what caused the change.
Your Win by Friday
By Friday, you will have:
- A ranked list of your next 5 experiments (impact + confidence scores).
- One experiment selected and ready to launch.
- A clear reason why you picked it (no more "it felt right").
That's it. One small move. One clear priority. No guesswork. And hey, you might even have time to grab coffee before the results come in.
