Prompt visibility

What it is

Prompt visibility is the percentage of monitored prompts in which a brand or domain appears at least once in the generated answer, whether cited or merely mentioned. It measures presence rather than dominance.

Why it matters

It is the AI-search analogue of keyword ranking coverage, telling you how much of the relevant question space your brand shows up in at all, which is the precondition for any AI-driven discovery.

How it works

A practitioner defines a representative prompt set, runs it on a schedule, and counts the share of prompts where the brand surfaces, then widens coverage by addressing the topics and questions where it is currently absent.

When it applies

Use it as the headline coverage metric whenever you are establishing or auditing presence across a category of AI queries.

Examples

• A brand appearing in 60 of 200 monitored prompts has visibility across roughly a third of its question space
• A new entrant tracking which buyer questions it is still invisible for
• A team prioritising content for the prompts where competitors appear but they do not

How it is measured

• Count of prompts with at least one brand appearance divided by total prompts
• Prompt visibility split by funnel stage or intent
• Visibility gap against named competitors
• Change in visibility after publishing new coverage
