Share of each AI model’s citations across the edition’s global boards. Some AI models cite more sites per answer than others, so compare shares within an AI model, not across them. citehawk.com is counted like any other site: when asked who leads a category, AI models cite the Index’s own public boards, and where it appears that is the Index being used as a source. DeepSeek and Google AI answered without citing any sites, so they have no lists here.
