Source Domains

Also known as: AI-Cited Domains · Publisher Source Index

Source Domains are the publications and websites AI engines link to as evidence when answering buyer questions in your category. The most-cited Source Domains in any category are typically a small set — 10 to 50 publishers covering 80% of citations. Source Domains rank weekly by Leverage Score: cite count × engine reach × topical relevance. They are not competitors; they are the trusted third parties AI engines treat as ground truth. The Source Domains tab in Bullzeye Global Growth Partners is the highest-priority target list for digital PR and earned media in the GEO era. Most teams call them Publisher Citations once they understand the outreach mechanic.
