What is Domain Authority (DA)?

Key answer

Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages, measured on a logarithmic scale from 0 to 100 based on link profile strength.

This guide explains how domain authority (da) works, how it compares to related concepts, when to use it, and how Anthroly's AI agents plus human-led SEO help you implement it for Google and AI answer engines.

How does Domain Authority (DA) work?

Domain Authority is calculated using machine learning algorithms analyzing: total linking root domains, total backlinks, MozRank (link popularity), MozTrust (link trustworthiness derived from trusted seed sites), and spam score. The logarithmic scale means improving from 20→30 is significantly easier than 70→80—each point requires exponentially more links at higher levels. DA should be used for: competitive comparison (is your DA higher/lower than competitors for target keywords?), link prospecting (targeting sites with higher DA for backlinks), and progress tracking over time. DA should NOT be used as an absolute measure of ranking ability—it's a proprietary metric that doesn't directly influence Google. Similar metrics: Ahrefs Domain Rating (DR), Semrush Authority Score, Majestic Trust Flow/Citation Flow. All are third-party approximations of Google's actual authority signals.

What are practical examples of Domain Authority (DA)?

These real-world examples show how domain authority (da) shows up in modern search and AI answers:
  • A new website starting at DA 1, reaching DA 30 after 12 months of consistent link building
  • Major sites like Wikipedia (DA 100), NYTimes (DA 95) demonstrating ceiling of the scale
  • Using DA filter in outreach to prioritize backlink targets above DA 40
  • DA drop of 5 points after disavowing toxic backlinks, followed by traffic increase
  • Comparing your DA 35 against competitor DA 55 to set realistic ranking timelines

What are the risks of ignoring Domain Authority (DA)?

Skipping domain authority (da) usually means weaker extractability for AI Overviews, thinner topical authority, and slower ranking movement when competitors publish clearer, better-structured answers. Teams that treat domain authority (da) as a one-off tactic—not an ongoing practice—lose citation share as answer engines refresh sources.
