One variable per test
A result you can read: you know why the winner won.

Prompt instructions
Give me a step-by-step plan I can follow this week, for a short video about [your product], for [your audience]. The technique is one variable per test: a result you can read: you know why the winner won. How it works: each variant gets an id, a hypothesis, the one thing it changes, what stays fixed, a cost, an observation window and the result that would justify the next test. It is right for: testing hooks and formats, organic or paid. Ten creatives that differ in everything can find a winner and still not tell you why. Stage A explores formats. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
The same prompt works in Claude, ChatGPT and Gemini.
