Why This Prompt Exists
Most testimonial ads fail because they quote praise without proving transformation.

You get:

  • “Great product!” (vague, unconvincing)
  • no before/after contrast
  • no visual support for the claim
  • testimonials without numbers
  • ads that feel like bragging, not proof

But a testimonial is not a compliment.

It is evidence of transformation.

  • The before/after structure makes the transformation visible
  • A quoted headline is more powerful than a written one
  • Visuals make testimonials believable
  • A testimonial without a specific result is just an opinion

Without structure, testimonials are wallpaper.

This framework forces AI to turn praise into proof.

The Prompt
Assume the role of a Facebook Ads copywriter who turns customer praise into scroll-stopping testimonial ads.

Your task is to convert a customer testimonial into a high-converting ad.

Generate:

1. TESTIMONIAL AD (40 words)
   Using the customer's own words (minimally edited for clarity)

2. BEFORE/AFTER STRUCTURE
   What the customer struggled with before vs. what changed after

3. HEADLINE
   A quote pulled from the testimonial

4. VISUAL SUGGESTION
   What image or short video clip would make this testimonial believable

5. FLAG (if no specific result)
   "Needs a number — ask customer: 'What measurable outcome did you get?'"

INPUTS:

Customer Testimonial (raw):
[PASTE THE TESTIMONIAL]

Product or Service:
[WHAT THEY'RE TALKING ABOUT]

Customer's Industry or Context (optional):
[WHERE THEY USE THE PRODUCT]

Do You Have Permission to Use This Testimonial?:
[YES / NO — if no, stop]

RULES:
- Use the customer's own words — minimal editing only for clarity
- The before/after must be specific, not "they were struggling, now they're happy"
- If the testimonial has no specific result, flag it immediately
- The visual suggestion must be specific (e.g., "customer using product in their workspace")
- Do not add fake quotes or embellish
How To Use It
  • Only use testimonials with permission (written or recorded).
  • Testimonials with numbers convert 3x better than those without.
  • The visual suggestion is not optional — people trust what they see.
  • If a testimonial is weak, don’t use it — wait for a better one.
  • Run testimonial ads as retargeting, not always as cold audience ads.
Example Input

Customer Testimonial (raw): “I’ve been using this software for three months and I really like it. It’s saved me so much time. My team is way more organized now. I’d recommend it to anyone.”

Product or Service: Project management software for small teams

Customer’s Industry or Context: Marketing agency owner

Do You Have Permission to Use This Testimonial?: Yes

Why It Works
Most testimonial ads fail because they quote praise without proving transformation.

This framework improves outcomes by forcing:

  • before/after structure (visible change)
  • customer’s own words (credibility)
  • specific visual suggestions
  • metric flagging (numbers matter)
  • permission verification (legal safety)

Great testimonial ads don’t say “people love us” — they show someone who was exactly like you, now better off.
