Understanding Domain Authority & Page Authority in SEO
Table of Contents
What is Domain Authority (DA)?
Domain Authority (DA) is a score (ranging from 1 to 100) that predicts how well a website will rank on SERPs. It is based on multiple factors, including the number of backlinks and the quality of referring domains.
Importance of DA:
-
Helps in competitor analysis
-
Determines site credibility
-
Affects organic search performance
What is Page Authority (PA)?
Page Authority (PA) is similar to DA but focuses on individual pages instead of an entire domain. PA also scores from 1 to 100 and is influenced by backlinks, content quality, and internal linking.
Importance of PA:
-
Determines ranking potential of a specific page
-
Helps in content strategy
-
Impacts individual page visibility

Moz’s algorithm evaluates various ranking factors to determine DA and PA. These scores are updated regularly, meaning they fluctuate based on competitive and algorithmic changes.
Key Components:
-
Link Profile – Quality and quantity of inbound and outbound links.

Root Domains – Number of unique referring domains.
-
MozRank – Evaluates link equity.
-
MozTrust – Measures the trustworthiness of a website.

Content Quality – Engaging and authoritative content influences PA more.
