AI Prompt for Facebook Ad Copy That Converts
Generate multiple ad copy variations built around a proven hook-problem-solution structure.
The Prompt
Write 3 Facebook ad copy variations for [PRODUCT/SERVICE]. Target audience: [DESCRIBE AUDIENCE]. Each ad must include: a scroll-stopping first line (a question, bold claim, or specific pain point), 2-3 sentences connecting the problem to the solution, one line of social proof or specificity (numbers, timeframe, guarantee), and a clear call-to-action. Keep each ad under 90 words. Vary the angle across the 3 (e.g. pain-point-led, curiosity-led, result-led).
Example
Product: a $19/month subscription box of woodworking project kits. Audience: beginner hobbyists aged 30-55 who want a creative hands-on hobby but don't own tools.
Ad 1 opens with a pain-point hook ("Bought a Pinterest-worthy toolbox and never used it?"), Ad 2 opens with curiosity ("The $19 box that turns Sunday afternoons into finished projects"), Ad 3 leads with a result ("3,000+ beginners built their first project in one weekend") — each ending with a clear CTA like "Get your first box →".
Tips for Better Results
- Give the AI real customer language if you have it — actual reviews or support messages produce far more authentic hooks than generic descriptions.
- Test the 3 angles against each other with a small ad budget before scaling spend on any one.
- Ask for a 4th variation specifically for retargeting an audience that already visited your site but didn't buy.
FAQ
How long should Facebook ad copy be?
Shorter, scannable copy (under 90-125 words) generally performs better in feed placements, since most people are scrolling quickly and decide whether to engage within the first line or two.
Should every ad have a discount or offer?
Not necessarily — social proof, urgency, or a strong guarantee can be just as effective as a discount, and relying only on discounts can train an audience to wait for sales before buying.
