11 Rules of Marketing They Don’t Teach in School

You learned Maths, Physics and Economics.

But nobody taught you how to do marketing when the strategy stops working.

Most marketing education stops at the tactic.

It doesn't teach you what breaks when the budget is real,
When the team is under pressure, and when the data is incomplete.

Over the years, I learned these 11 rules:

🚨 The Signal Rule

Most brands have more data than they can act on.
The skill is knowing which numbers change what you do next.

📝 The Brief Rule

Creative quality is decided before anyone opens a design tool.
A weak brief produces weak output. Talent doesn't change that.

📈 The ROAS Trap

ROAS tells you what happened inside a brief window.
Never build a strategy from a snapshot.

📉 The Fatigue Rule

Your audience tires of an ad long before the budget runs out.
Rotate creative before performance drops.

📊 The Attribution Gap

Attribution assigns credit. It doesn't explain behavior.
Knowing which channel drove conversion doesn't tell you what drove the decision.

🛠️ The Structure Rule

Most paid media underperformance is a structural problem.
Fix the account before you fix the ad.

💪 The Consistency Rule

The brands that win over time are the most consistent.
Familiarity converts. Consistency builds it.

📤 The Distribution Rule

Where something lands determines whether it works.
Decide the channel before you make the asset.

🎯 The Metric Mirror

Whatever you measure and reward is what your team will produce.
Audit your KPIs against the outcomes you want before you set them.

⚡ The Speed Rule

Most growth decisions are reversible.
Waiting for perfect information on a reversible call comes with a high cost.

🪜 The Ceiling Rule

Every channel has a ceiling. What works at $50k a month rarely works at $500k.
Plan for the next channel before you hit it.

None of these are original.
Most of them you already know.

The question is which ones you're ignoring right now.

Push back on any of them.
I'm more interested in the ones people disagree with.
