Prompt
Definition
A prompt is the input text or instruction a user or system gives a language model to steer its response.
Full definition
Prompts can be questions, tasks, or multi-turn context. In AI visibility work, “prompt testing” means asking models how they recommend products or explain topics and recording which brands appear.
Prompts are measurement and product-design tools, not a substitute for public web signals. See Share of Voice and AI Visibility.
