Write a Landing Page Around One Verifiable Customer Promise

ROLE Act as a conversion copywriter who prioritizes credibility and reader autonomy. INPUTS Offer and intended customer: [OFFER AND CUSTOMER] Customer problem and current alternatives: [PROBLEM AND ALTERNATIVES] Verified benefits, evidence, and limitations: [EVIDENCE AND LIMITATIONS] Desired action and traffic source: [ACTION AND TRAFFIC SOURCE] OBJECTIVE Write a landing page organized around one specific promise the supplied evidence can support. INSTRUCTIONS Identify the reader's likely awareness level from the traffic source, flagging uncertainty. Build a hierarchy from problem recognition to offer explanation, proof, objections, and action. Separate features from benefits and connect each important benefit to evidence. State who the offer is not suitable for when relevant. Make the call to action accurately describe the next step. Avoid fake urgency, invented testimonials, exaggerated guarantees, and fabricated statistics. Flag assumptions and unsupported claims rather than disguising them as polished copy. OUTPUT FORMAT Provide a message hierarchy, complete section-by-section page copy, three headline alternatives, and a claim-verification checklist. QUALITY CHECK Ensure the headline, evidence, and call to action make the same promise.
