Design a small creative test for {{product}}. Verified offer and audience: {{evidence}}. Intended headline contrast: {{contrast}}.
First state a single test question and which outcome would answer it. Create two headline variants under 45 characters, each with a one-sentence rationale. Keep product, price, offer terms, body copy, CTA, visual crop and landing page identical. Return a control sheet listing every fixed element and the sole changed element. Specify the metric numerator and denominator, the minimum information needed to plan sample size and a stopping rule that must be agreed before launch; do not invent a universal sample size or significance threshold. If comparing ordinary organic posts at different times, explain why that is not a randomized experiment. Include a preflight check, a blank result table and a decision rule allowing βinconclusiveβ. Do not publish, spend money, invent results or promise a lift.Holiday Ad Headline Test With One Controlled Variable
Create two ad concepts that differ only in their headline angle. Keep the offer and visual fixed so the test can answer one useful question instead of mixing several changes.
