Adaptable structures.
FOR A PRODUCT DESCRIPTION
"Write a description for [product]. Buyer: [who and why]. Specifications: [data]. Include size and materials. Answer the question that would prevent a purchase. Around eighty words. No superlatives."
FOR A LANDING PAGE
"Write landing page copy for [offer]. Visitor: [who, what brought them]. Main objection: [what]. Evidence: [supply it]. One action: [what]. No superlatives."
FOR HEADLINES
"Ten headline options for [page]. State what it is and who it is for. Under sixty characters. No questions, no superlatives."
FOR AN EMAIL CAMPAIGN
"Write a campaign email about [offer]. Audience: [who]. Under 200 words. One clear action. Plain, as though writing to a customer I know."
FOR SOCIAL POSTS
"I did [what actually happened]. Write a caption for [platform]. Conversational. Modest relevant hashtags."
THE CRITICAL SUPPLY
What actually distinguishes you, and your real evidence.
The model will invent generic differentiation otherwise.
