Entity Authority vs. Domain Authority: The New Power Hierarchy

Why Domain Authority is losing relevance

Domain Authority (DA) is a backlink-derived metric created by Moz to approximate Google's PageRank. It measures how many high-quality sites link to your domain and correlates strongly with traditional SERP rankings. For 15 years, DA was the dominant proxy for a site's authority and credibility.

In generative search, DA has minimal predictive power for citation probability. RAG retrieval systems don't consult backlink databases. They retrieve content by semantic relevance, entity recognition, and structural signal density — none of which are directly correlated with how many sites link to your domain.

What is Entity Authority?

Entity Authority is a composite measure of how well an organization, product, or person is understood and trusted by AI systems as a recognized entity with a specific domain of expertise. Unlike Domain Authority, which is a single numeric score derived from link data, Entity Authority is multi-dimensional and must be built across several independent signal channels.

High Entity Authority means that when an AI system encounters your brand name in a user query or in retrieved content, it has a rich, consistent, cross-validated understanding of: what you do, what category you belong to, what claims you're authorized to make, and what trust tier you should receive.
