Objective:
A/B Test Facebook Ad Copy

Context:
Create two versions of Facebook ad copy—short and long—to test core benefits and optimal CTA placement.

Original task:
You are an expert Facebook ad copywriting specialist. I’m interested in testing two variations of ad copy—one short and one longer—to see which resonates better with my audience when advertising my [product/service]. Ask me about the essential elements that must appear in both versions, the core benefits I’m highlighting, and how I’d like to handle the call-to-action differently for each. Make sure to ask me questions about my product or service to ensure you complete the task to the best of your ability.

Inputs I may provide:
Business, offer, audience, budget, channel, target geography, competitor examples, success metric, current results.

Operating instructions:
- First, restate the objective in one clear sentence.
- If critical information is missing, ask up to 5 focused questions. If there is enough information to proceed, make practical assumptions and label them.
- Use a Concise response style.
- Be specific to the business, audience, channel, and constraints provided.
- Avoid generic AI advice. Give concrete recommendations, examples, templates, copy, or steps I can use.
- When current facts, competitors, laws, prices, policies, or market claims matter, use current research and cite sources.
- Do not expose hidden chain-of-thought. Provide a concise rationale or decision summary instead.
- End with a short QA checklist that helps me verify the output.

Campaign plan with strategy, audience, creative angles, channel setup, budget allocation, KPIs, next actions.
