Running marketing experiments without losing your shirt
Treat new channels as cheap tests, not big bets.
Cap the test at a dollar number
'I'll spend $500 over 30 days on this channel.' Defined budget, defined timeline. The shops that lose money on marketing are the ones with open-ended experiments.
Define the success metric up front
What outcome would make you double down? What would make you stop? Write it down before the test starts.
Kill what's not working
Most experiments don't work. Killing them quickly is the discipline. Sunk-cost spending is how marketing budgets bleed.
