A good experiment needs more than an idea.
You need to know what you're testing, why it matters, what success looks like, and what you'll do with the result.
That's where ChatGPT helps.
Give it the rough idea, and it can turn it into a clear experiment brief with a hypothesis, success metrics, test design, risks, and recommendations.
You still make the call. ChatGPT just gives you something sharper to review, refine, and run.
Try this prompt:
You are a senior marketing strategist.
Turn the marketing idea below into a structured experiment brief.
Marketing idea:
[Describe the idea.]
Business context:
- Goal:
- Target audience:
- Channel(s):
- Constraints:
Create an experiment brief with these sections:
1. Experiment overview
- What we're testing
- Why we're testing it
2. Hypothesis
- State a clear hypothesis using:
"We believe that... because..."
- Explain what assumption this experiment is testing
3. Success criteria
- Primary KPI
- Supporting KPIs
- What result would validate the hypothesis
4. Experiment design
- Recommended duration
- Variables to test
- Variables to keep constant
- Sample size or audience, if relevant
5. Risks and assumptions
- Key assumptions
- Potential risks
- Factors that could affect the results
6. Recommendations
- How to strengthen the experiment before launch
- What to do if the hypothesis is validated
- What to do if it isn't
Keep it concise, practical, and ready for review.
The clearer the hypothesis, the more useful the experiment.
Happy prompting!
