What is Page Authority in SEO: A Simple Guide to Boost Your Rankings

Table of Contents

Page Authority (PA) is an estimate of ranking strength that search engines assign to a webpage. It works as a metric to show how likely a page is to rank well in search engine results. Think of Page Authority as grades that reflect how much search engines tend to trust and give value to that page. This is based on several factors, but mostly pertains to the quality and quantity of backlinks to that page.  Page Authority may suggest to SEO practitioners the possibility that a specific page might need some serious treatment, links, or fresh content. While it’s not an explicit factor in Google rankings, Page Authority signals are indeed representative of various signals of interest to search engines.

What is Page Authority?

Page Authority is a score from 1 to 100 that predicts how well a specific page will rank in search results. A higher Page Authority score typically has a better chance of appearing on page one of Google. This score was developed by Moz, a popular SEO software company.

Origin and Purpose of PA

  • Created by Moz to help analyse page-level SEO strength.
  • Based on data like backlinks, linking root domains, and content strength.
  • It’s a predictive score, not a direct Google ranking factor.

How It’s Calculated

Moz uses a machine learning model that looks at:
  • The number and quality of inbound links
  • How authoritative those linking domains are
  • Other page-level SEO signals
Note: PA scores can change over time as Moz’s algorithm improves or as your link profile changes.

Page Authority vs Domain Authority

Many people confuse Page Authority (PA) with Domain Authority (DA).

Key Differences

Feature Page Authority (PA) Domain Authority (DA)
What it measures Strength of a single page Strength of the entire domain

Which One Matters More?

Both are useful, but if you’re targeting rankings for a specific page, then efforts should be made to increase its Page Authority while recognising in your long-term SEO strategy to keep an eye on your Domain Authority. Read more about: What are DA and PA in SEO?

Why Page Authority is Important for SEO

When it comes to rankings, higher Page Authority allows you to rank better for competitive keywords. Page Authority is important for the following reason: 
  • Helps You Identify Page-Level Performance: PA shows you which of your pages are ranking well and which of your pages need improvements to enhance their ranking ability.
  • Supports Link Building Strategy: You can focus your efforts on building links to specific pages with low PA.
  • Boosts Your Page’s Ranking Chances: A higher PA can increase a page’s visibility, traffic, and credibility.
