Prompt set

A prompt set is the curated collection of queries used to measure a brand's AI visibility, ideally spanning category discovery, comparison, problem-led and brand-specific intents.

Prompt selection determines the answer more than any other choice. A set weighted to brand-name queries will always look flattering and will never reveal category risk.

Twenty to sixty prompts covers most brands; beyond that, additional samples per prompt usually buy more insight than additional prompts.
