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

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.
