"The ad isn't converting" is a symptom, not a diagnosis. Conversion fails at one of four stages — and the fix for each is completely different. Work through them in order.
The stages are sequential: a viewer who leaves at second 4 never encounters your message, offer, or landing page. Fixing a landing page for traffic that never clicks is wasted work. And attention is the only stage you can measure before spending — upload the ad to PreTestAds and the engagement curve shows whether your hook survives the scroll, the exact second attention drops, and whether viewers are still present when your CTA lands (Purchase Signal).
If the creative scores strong and conversions are still weak, you've eliminated stage 1 for the cost of one credit — now your live data is actually about message, offer, and page, and your A/B tests get much cheaper to interpret.
Score the creative first ( what pre-testing measures). If Hook Strength is weak, recut the opening. If there's a mid-ad attention drop, trim or rework that segment. If the creative scores well, pull your funnel numbers: CTR low → message problem; CTR fine but page conversion low → offer or page problem. One hour of diagnosis beats another month of budget spent guessing.
