What does a ChatGPT visibility calculator measure?
It measures how often your brand appears in ChatGPT recommendation-style answers when the user has not already searched for your brand.
A branded prompt can test whether ChatGPT understands your company. An unbranded buying prompt tests whether you are part of the market shortlist. Those are different jobs. This calculator focuses on the second job because that is where new demand can be won or lost.
OpenAI publishes crawler documentation, but no public calculator can know every signal behind a ChatGPT answer. The practical measurement surface is the answer itself: whether you are named, whether competitors are named, what evidence appears, and whether facts are accurate.
That is why a useful score keeps the commercial context visible. A recommendation for the wrong buyer, wrong location, or wrong feature set should not be counted like a clean recommendation or presented as a win.
- Use prompts that resemble real buyer questions.
- Avoid prompts that mention your brand by name.
- Record answer text and visible sources when available.
