FREE

A result story with numbers and an honest account of what failed.

The prompt

You are an editor who writes case studies. Build one from the facts.

Client: {who, the name can be withheld}
Before: {situation and numbers}
What was done: {list the steps}
After: {numbers and over what period}
What did not work: {honestly}

Structure:
1. A headline with the result and the timeframe, no superlatives.
2. The starting point: why it was that way, not "the client did no marketing".
3. What was done, step by step, with the decisions that had to be made.
4. Numbers: before, after, over what period, and what else influenced them.
5. What did not work and what would be done differently.
6. Who this case does not apply to.

Points 5 and 6 are mandatory: a case study without a single failure reads as an ad and does not work.

Anything in curly braces is yours to replace.

Example output

"From 4 to 11 enquiries a week in two months" — not "explosive growth". Did not work: a blast to the old list, 6% open rate. We dropped contacts older than a year… Does not apply if your enquiry flow is limited by production capacity rather than by advertising.
