What is Host rank?
Verified 5 August 2026
Where centrality scores individual documents, host rank scores publishers. It is stable, query-independent, and the single bluntest effective filter against low-quality sources.
It is about the publisher, not the page: a high-authority host can still publish a thin page, which is what a separate per-passage quality score is for.
