Testing AI-generated variants

Lesson 7 of 8 · 30 min · part of the AI Marketing Specialist certification

AI can produce 50 headlines in a minute. That does not mean you know which one works. Only a properly designed test tells you — and the more variants you test, the more likely one "wins" by pure chance.

• Decide the sample size before you start, based on the smallest lift worth detecting.
• Test few variants — 2 to 4. Pre-select with judgment; don't test 50.
• Don't peek and stop early when one looks ahead; early leads often vanish.
• Pick one primary metric (e.g. clicks or conversions) before launching.
• Record the result, including losers, so you don't re-test the same idea.
