Creative testing compares variants (hooks, formats, offers) under controlled conditions to find winners. Structure tests with one variable changed per cell; avoid Advantage+ blending variants before you have readouts. Document learnings — “UGC hook B beat studio A on TikTok” — for the next flight.
Statistical significance needs enough spend per variant — don’t call winners on 48h / $50.
