Prompt: Write a Case Study

Case studies sell. But writing them takes forever, which is why most businesses have 2 when they should have 20. This prompt write case study produces a structured draft from your client details and results data.

Fill in the blanks. Get a case study worth publishing.

The Prompt

You are a marketing writer creating a compelling case study. Follow the problem-solution-results format exactly.

CLIENT DETAILS:
- Client name (or anonymous descriptor): [e.g., "a mid-size dental practice" or "Sarah, owner of XYZ Dental"]
- Industry: [their industry]
- Company size: [employees, revenue range, or patient count]
- Their situation before: [what was going wrong or what they needed]

THE ENGAGEMENT:
- What we did: [describe the work in plain terms]
- Timeline: [how long the engagement lasted]
- Key actions: [3-5 specific things you did]

THE RESULTS:
- Primary result: [the headline number - be specific]
- Secondary results: [2-3 additional outcomes]
- Client quote: [if available, paste a real quote. If not available, write "no quote available"]
- Timeline to results: [how quickly results appeared]

WRITE THE CASE STUDY WITH:

1. HEADLINE: "[Result] in [Timeframe] for [Client Type]" format
2. THE CHALLENGE: 2-3 paragraphs painting the before state. Make the reader feel the problem.
3. THE SOLUTION: 2-3 paragraphs explaining what you did and why. Focus on the approach, not the technical details.
4. THE RESULTS: Lead with the headline number. Then supporting results. Include the client quote.
5. KEY TAKEAWAYS: 2-3 bullet points that generalize the lesson for other businesses in similar situations.

RULES:
- Specific numbers beat vague claims. "$14 CPA" not "significantly reduced cost"
- Write in third person for the client, first person plural for us ("we")
- No corporate jargon. A business owner should read this and think "I want that"
- Under 600 words total
- The headline should make someone want to read the full case study

Turning Results Into Stories

The difference between a case study and a testimonial is the story. The challenge section makes the reader identify with the problem. The solution section shows you know what you are doing. The results section proves it.

That narrative arc is what sells. Raw numbers impress. Stories with numbers convince.

Building a Case Study Library

Run this prompt for every client engagement that produced measurable results. Aim for at least one case study per industry you serve and one per service you offer.

When a prospect says "have you worked with businesses like mine?" you should have a case study to share within 30 seconds.

Keeping Them Current

Case studies lose power as they age. Update the results annually if the client relationship continues. "18 months later, the CPA is still under $15 and total leads have exceeded 2,000."

Fresh data makes old case studies new again.
