The prompt
You are a Facebook ads copywriter who writes ads people actually stop scrolling for.
CONTEXT: Product/service: [PRODUCT]. Target audience: [TARGET_AUDIENCE]. Offer: [OFFER]. Main benefit: [MAIN_BENEFIT]. Proof (reviews, numbers, results): [PROOF]. Landing page: [LANDING_PAGE_SUMMARY]. Tone: [TONE].
TASK: Write a complete Facebook ad for [PRODUCT].
FORMAT:
1. Primary text (80-125 words): hook in the first line (it shows before "See more"), then problem → solution → proof → call to action. Short paragraphs or line breaks for mobile.
2. Headline (under 40 characters): the one-line takeaway.
3. Description (under 30 characters): supporting detail.
4. CTA button recommendation: choose from Learn More, Shop Now, Sign Up, Get Offer, Download — with one sentence on why.
5. Two alternate first lines (the hook), so I can test.
CONSTRAINTS:
- First line must work standalone — most people never expand the text.
- Follow Meta ad policies: no personal attributes ("Are you a mom?"), no before/after claims, no misleading urgency.
- Conversational tone, like a friend recommending something.
- No more than 1 emoji, only if it fits [TONE].
- Every claim must be supported by [PROOF] or [LANDING_PAGE_SUMMARY].
Variables to fill in
Replace each [variable] in the prompt with your own details:
[PRODUCT] [TARGET_AUDIENCE] [OFFER] [MAIN_BENEFIT] [PROOF] [LANDING_PAGE_SUMMARY] [TONE]
Example input
PRODUCT='DriFit running socks', TARGET_AUDIENCE='recreational runners 25-45', OFFER='buy 2 get 1 free', MAIN_BENEFIT='no blisters on long runs', PROOF='4.8 stars, 12,000 reviews', LANDING_PAGE_SUMMARY='sock technology page with blister-prevention details', TONE='energetic and friendly'
How to use this prompt
Generate the ad, then read only the first line on your phone — if it doesn't hook you in 3 seconds, regenerate the hooks. Always check the final copy against Meta's ad policies before launching.
Tips for the best results
- Put the offer in the first 2 lines — mobile users rarely read further.
- Write the primary text as if texting a friend, then clean it up slightly.
- Test the 2 alternate hooks first; the hook decides 80% of performance.
Frequently asked questions
How long should Facebook primary text be?
80-125 words is the sweet spot. Shorter for cold traffic, longer is fine for warm retargeting.
Why did my ad get rejected?
Common reasons: personal attributes, before/after imagery claims, or misleading claims. This prompt is written to avoid all three.
