Persuasive content.
HOW TO BRIEF IT
"Write copy for [product] aimed at [specific customer]. Their problem is [problem]. What distinguishes us is [specific difference]. Include [evidence]. Plain language, no superlatives. One clear action."
WHAT YOU MUST SUPPLY
What actually distinguishes you.
The model will invent something generic otherwise.
WHAT TO BAN
"Revolutionary", "cutting-edge", "world-class", "unlock", "empower", "seamless", "game-changer".
Listing banned words works.
WHAT MAKES COPY FAIL
Describing features rather than what the customer gets.
Ask explicitly: "focus on what the customer gets, not what the product has".
FOR HEADLINES
"Ten options. State what it is and who it is for. Under sixty characters. No questions, no superlatives."
VERIFY EVERY CLAIM
Marketing claims you cannot substantiate are a legal risk in many jurisdictions.
Never publish a claim the model generated unless you can support it.
