AI Visibility Index

AI 可见度指数AI Terms

In one sentence

A composite score used by Starbox GEO to measure a brand's exposure in AI responses. Calculated using the same fixed prompt set, it enables direct comparisons between diagnostic rounds.

The calculation evaluates several dimensions: how many prompts include the brand in their answers, how prominent the brand placement is, how accurate the description is, and whether the brand's own content is cited.

The index is meaningful only when comparing results across the same prompt set and the same group of AI models, which is why every retest uses a fixed prompt set.

Example

During the initial audit, the brand appeared in answers to only a few prompts. In the retest one month later, the number of prompts mentioning the brand increased noticeably, driving up the index.
