# Retrieval Authority

> Retrieval authority is the retrieval-layer equivalent of domain authority — the probability that a domain's content will be retrieved and cited for a given sub-query cluster.

*Core concept* · *Citation & Visibility Measurement*

## Definition

Retrieval authority is the retrieval-layer equivalent of domain authority — the probability that a domain's content will be retrieved and cited for a given sub-query cluster, based on domain trust signals, semantic density, passage-level retrieval readiness, and citation history.

## Why It Matters for AI Search

Retrieval authority is what accumulates when retrieval optimization work compounds over time. Each citation earned feeds the domain's trust signals in the index. Each well-structured spoke page adds to the domain's semantic footprint in its topic cluster. Unlike domain authority, which is primarily link-based, retrieval authority is built through the combination of structural content quality and citation history — both of which are directly actionable.
