How to Design a Low-Lift, High-Learning Experiment

Lesson 2: Don't turn your small experiment into a giant project.

You’ve picked what to test. Now comes the tricky part: not turning your small experiment into a giant project.

A Rube Goldberg machine

I’ve seen it (and been guilty of doing it) too many times: what starts as a “quick test” becomes a days-long slog of writing briefs, setting up tools, designing new assets, and pulling teeth to get alignment.

So here’s how I keep it light and learn fast:

🎯 1. Focus on one variable

You’re not launching a new campaign. You’re isolating a single factor to learn from.

Change just one thing:

• A subject line

• A CTA

• A landing page headline

• A LinkedIn post format

If you change multiple things at once, you’ll never know what actually made the difference. Then it’s not an experiment — it’s just vibes.

📏 2. Define what “good enough” looks like

You don’t need statistical significance. You need a directional signal.

Some questions I ask:

• “How many impressions or clicks would give me a gut-level confidence boost?”

• “How long do I need to run this before I learn something useful?”

• “What’s the simplest way to track this?”

For small audiences, you’ll never have enough volume to meet textbook thresholds. That’s okay. That’s why these are “small experiments” and not A/B tests. What matters is whether the result changes what you do next.

⚡ 3. Make it shippable within a day

If your experiment takes more than one workday to launch, it’s either too complex or not truly a test.

A few things I skip:

• Fancy dashboards

• Long-form documentation

• Cross-functional sign-off for something <$500

Instead, I write a quick brief:

“We’re testing X because we want to learn Y. If Z happens, we’ll do A next.”

Then I ship it.

🧪 Example: The “Resonant Content” Test

A few months ago, I had an idea itch I wanted to scratch. I had a little rant about sales one-pagers, but before fleshing out the full blog post, I wanted to see if it was a topic my audience even cared about. So I fired off a quick LinkedIn post:

The post got over 54,000 impressions and reached more than 30,000 people. It closed in on 900 likes and got 176 comments. People were really engaged with it.

Time I spent drafting like LinkedIn post? 10 minutes.

It was a fast, low-risk test to see if people actually wanted the full version of this thought, with recommendations for how to move forward without a traditional sales one-pager.

The result?

I went on to spend several hours writing and producing the blog post, Why One-Pagers Are Dead (And What to Send Instead), which became one of our most viewed posts of 2025.

Because the LinkedIn post resonated early, I felt confident investing more time and energy into building it out.

That’s the power of a small, smart experiment: it protects your time and sharpens your content bets.
