What is the STAR formula?

STAR — Situation, Task, Action, Result — is the copywriting framework for customer success stories. While most formulas are designed to persuade through emotion or logic, STAR persuades through proof: the lived experience of a real person who had the same problem your reader has now, and found the answer in your product or service. A well-structured STAR case study does something testimonials and feature lists can't — it makes the transformation feel real, specific, and repeatable. And specific, repeatable transformations are what convert browsers into buyers.

Step by step

The 4 stages of STAR

S
Stage 1
Situation
Set the scene. Who is the client? What was their world before?
↓

The Situation stage establishes the context that makes the rest of the story meaningful. Name the client, their industry, their role, and the circumstances they were in before your product entered the picture. The more the reader identifies with the client's Situation, the more powerfully the Result will land. This is where you recruit the reader's empathy.

Do
  • Name the client, their role, and their industry specifically
  • Describe the Situation in terms the reader immediately recognises
  • Make the Situation feel like the reader's own world
  • Keep it concise — this is context, not the story itself
Don't
  • Use a client situation so niche the reader can't relate to it
  • Spend too long on background before getting to the Task
  • Anonymise so heavily that the Situation loses credibility
  • Lead with the solution — Situation must come first
T
Stage 2
Task
What was the specific challenge or goal they needed to achieve?
↓
A
Stage 3
Action
What did they do — or what did you do for them — to address it?
↓
R
Stage 4
Result
The measurable outcome. Specific numbers always outperform vague praise.

Real example

Real example — case studyA freelance copywriter writing a portfolio case study after working with an e-commerce client.
Situation“Sarah ran a 6-figure e-commerce store. Traffic was growing, but conversions stayed flat at 0.8% — well below the 2–3% industry benchmark.”
Task“Redesign the product page copy for the 12 bestselling SKUs to close the gap between traffic quality and conversion rate — without a redesign or additional ad spend.”
Action“Rewrote 12 product descriptions using FAB framework, added comparison table addressing the three most common objections, simplified the CTA from three options to one.”
Result“Conversion rate climbed to 2.4% in 30 days. That's $28,000 in additional monthly revenue from the same visitors.”

Watch out for

Common mistake

✕ Burying the Result or leaving it vague. "They were very happy" is not a result. "Revenue increased 34% in 60 days" is.
Avoid these

Common mistakes

✕ A vague or absent Result
FixThe Result is the only reason the reader is reading the case study. 'They were very happy' tells them nothing. '3x conversion rate in 30 days' tells them everything. Never publish a STAR case study with a weak Result.
✕ A Situation no one relates to
FixIf the client's Situation is too niche or unusual, the reader can't place themselves in the story. Choose or frame the Situation so your target reader sees their own world reflected in it.
✕ An Action that reads like a feature list
FixThe Action stage should read like a narrative decision, not a product menu. Show the thinking and the application, not just the tools used.
✕ Missing the Task stage
FixWithout a clear Task, the Result has no stakes. 'Revenue grew 40%' is less impressive than 'Revenue needed to grow 25% before their runway ran out — it grew 40% in 6 weeks.'
