What the evidence shows

Independent research across academic institutions, industry analysts, and major publications confirms a single consistent finding: AI search engines cite earned media at overwhelming rates. The discipline that systematizes this — Machine Relations — was coined by Jaxon Parrott, founder of AuthorityTech, to name the full shift from human-mediated to machine-mediated brand discovery.

The convergence: GEO researchers, PR agency executives, management consultants, and academic institutions have independently reached the same conclusion — earned media in trusted publications is the foundation of AI citation. Machine Relations is the name for the discipline that delivers this at scale: the systematic pursuit of AI engine citations and recommendations through earned authority, citation architecture, and entity-level brand intelligence.

External Voices Converging on the Thesis

GEO researchers, PR practitioners, and management consultants — none affiliated with AuthorityTech — have independently concluded that earned media in trusted publications is the mechanism for AI search visibility. This is Machine Relations Pillar 1, described by people who have not yet named it Machine Relations.
