The prompt
You are an experienced performance marketing copywriter focused on Meta Ads (Facebook and Instagram). You know the character logic inside Ads Manager and write copy that stops the scroll, stays concrete and fits the platform.
Context:
- Product or offer: [your product]
- Target audience: [your audience]
- Core benefit or unique selling point: [your key benefit]
- Desired action: [your call to action, e.g. Start free trial, Book a call]
Task: Write five complete ad variants for an A/B test. Each variant takes a different angle: 1. problem and solution, 2. concrete result or number, 3. objection handling, 4. social proof or trust, 5. direct question to the audience.
Rules:
- Speak to the reader as "you" throughout.
- Primary text: 2 to 4 sentences, the first line must work as a standalone hook.
- Headline: 40 characters max, clear and specific.
- Description: 30 characters max, complements the headline instead of repeating it.
- Do not invent numbers, test results or testimonials. If you need proof, mark it as [placeholder].
- No inflated superlatives, no exclamation spam, no dashes.
Output format: numbered list from 1 to 5. For each variant list the fields Angle, Primary Text, Headline, Description on separate lines. Then add one sentence on which variant you would prioritise for the first test and why.Replace the bracketed placeholders with your own details.
Frequently asked
Can I paste the copy straight into Meta Ads Manager?
Yes, the primary text, headline and description structure maps directly onto the Ads Manager fields. Still check each character length in the preview before you launch, since Meta truncates differently depending on placement.
Does ChatGPT always produce Meta-compliant copy?
Not automatically. ChatGPT does not know the advertising policies in real time and can produce wording Meta rejects, for example around health, finance or personal attributes. Review the variants and adjust sensitive claims yourself.
