Hold layout, motion, colors, and timing constant; swap *only* the field under test (hook, or offer, or CTA). Mixing two changes makes the winner uninterpretable. +2. **Message-match the hook to the CTA.** The promise made in the first 3 seconds must be the promise the button pays off. A "stop wasting 2 hours a day" hook ends on "Save 2 hours — try free," not a generic "Shop now." The hook and CTA are a matched pair in every row of the data table. + +## Ad anatomy (15–30s) + +| Beat | Job | Budget | +|---|---|---| +| Hook (0–3s) | Stop the scroll; state the problem or pattern-interrupt | 0–3s | +| Context | Make the viewer feel the problem / agitate | 3–8s | +| Payoff | Show the product as the solution, one clear benefit | 8–18s | +| Proof | One concrete number, demo, or result | 18–25s | +| CTA (last 3s) | Single action, message-matched to the hook | hold ≥2s | + +Land the hook's emotional trigger before the 2-second mark — judgment forms in ~1.7s and scroll speed keeps rising.
