GEO AISource share
Citation share
The proportion of AI answer citations across a tracked prompt set that point to a given domain, used as the AI-era analogue of ranking share.
In full
Citation share counts linked source attributions rather than mentions, which makes it more objective but narrower, a brand can be recommended by name without being cited. It is calculated per assistant, since citation behaviour and source pools differ sharply between them. Interpreting it requires care: a high share on a narrow prompt set means little, and citations to third-party review sites often matter more to a brand than citations to its own domain.
Example
Across 200 prompts, a vendor's domain is cited in 6% of responses while a comparison site it appears on is cited in 34%.
