Of AI citations are vendor-owned
When AI engines cite sources while recommending software, 68,651 of 133,527 citations point at domains owned by vendors in the Index registry — the industry writing about itself. Unresolved search-grounding redirector URLs (vertexaisearch, gemini citations before 2026-07-18) are excluded as noise; later gemini citations are resolved to their real sources.
