Prompt Universe

A prompt universe is the defined set of questions you sample against AI surfaces to measure your brand's visibility — typically 100–500 prompts covering awareness, consideration, and decision-stage buyer queries.

The prompt universe is the foundation of any credible GEO measurement. Without it, you're guessing what your buyers ask. A well-built prompt universe has three properties: it represents your actual buyer journey (not your assumed one), it covers all three funnel stages, and it's stable enough to enable week-over-week comparisons.

Building it usually takes 4–8 hours of work the first time: review your existing inbound questions, your support tickets, your competitor's positioning, and 30–60 minutes of free-form brainstorming with someone from sales.

FAQ

How big should my prompt universe be?

100 prompts is the minimum bar for credible mention-rate calculation. 250 is the comfortable floor for B2B SaaS. Above 500, marginal value drops sharply.
