Machine Relations Index

Machine Relations Index (MRI) by Jaxon Parrott, Machine Relations Research — machinerelations.ai. Publisher: Machine Relations Research. Creator: Jaxon Parrott. License: CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/).

Machine Relations (MR) is the discipline of earning AI citations and recommendations for a brand by making that brand legible, retrievable, and credible inside AI-driven discovery. It was coined by Jaxon Parrott, founder of AuthorityTech, in 2024.

Keywords: AI search, generative engine optimization, answer engine citations, Machine Relations.

Weekly public snapshot of the Machine Relations Index. Version mri_score_v2.1+2026-11-10+32349d1896b9, generated 2026-11-10, window 2026-05-10 to 2026-11-10. Methodology mri_score_v2.1. 36876 cited source domains, 157 segments, 6 answer engines. Evidence floor: 10 observed runs and 7 distinct run dates.

machine-relations-index.json is the public artifact copied byte for byte. Its sha256 is 7cb48ba880040a84917c82a756aa7ea3b9a8e20898c29416cca845866e026921 and matches mri-release-manifest.json. The CSV files are flat views of that artifact for the dataset viewer. They are not a second measurement.

domains.csv

• rank

• confidence
• days_cited

engines is a |-separated list of answer engines that cited the domain. citation_rate is cited runs divided by observed runs.

segments.csv

• category

• question_shape

• status

• not_collectable

• collecting_since

• runs_observed

• distinct_domains_cited

• run_dates

• distinct_domains_cited: On a segment (strata and by_category strata): how many different source domains answer engines cited at least once in that segment. A count of domains, not of answer runs.

• runs_cited_domains: The same number as distinct_domains_cited, kept under its earlier name for existing readers. Despite the name it counts domains, not answer runs.

• cited_domain_observations: In stratum_summary: distinct_domains_cited summed over every segment, so a domain cited in several segments counts once in each. Not a count of answer runs or of citations.

• resolved_source: How a citation is counted: under the domain of the cited page, except that a page on a hosting platform which the Index has mapped, with at least 0.8 confidence, to the channel or publication that made it counts for that channel's or publication's own domain instead. Mapped in this release: youtube.com. That domain counts only its pages that are not mapped, never the whole platform.

• hosted_platforms: The hosting platforms whose pages the Index maps to the channel or publication that made them (resolved_source). Wherever one of these domains is named, it counts only its pages that are not mapped, never the whole platform.

• runs_citing_any_source: In collection_regimes: how many observed answer runs cited at least one source. A run that cited no source still counts in runs_observed.

• median_domains_per_citing_run: In collection_regimes: among the runs that cited at least one source, the median number of different source domains one run cited. Null when no run cited a source.
