Ad copy
Use the PAS framework (Problem, Agitate, Solution) when the audience already knows they have a problem. It works particularly well for health, finance and B2B offers.
For cold traffic, lead with the outcome instead: 'Write 5 Facebook ad headlines for [product] that lead with the result the buyer gets, not the feature.'
Always ask for multiple variants and then test. A prompt that returns one option is a prompt that wastes the model's ability to explore the space.
Email sequences
Ask for the sequence, not one email: subject line, hook, body and a single CTA per message, with the logical thread between them spelled out.
Specify the emotional arc across the sequence - awareness, consideration, objection, urgency, close - so the emails do not all make the same argument.
Customer research
Build the avatar before the copy: demographics, top pains, desired outcomes, objections, and the exact words they use. Then feed that avatar back into your copy prompts.
Ask the model to list objections you have not addressed. It is a fast way to find the gaps in your sales page.
