Page Authority (PA) is a search engine ranking score developed by Moz that predicts how likely a specific web page is to rank in search engine results pages on a scale from 1 to 100.
Overview
Page Authority measures the ranking potential of individual web pages rather than entire websites, providing granular insights into page-level SEO performance. Moz calculates Page Authority using machine learning algorithms that analyze linking root domains, link quality, and other page-specific ranking signals. Page Authority helps SEO professionals identify which pages have the strongest potential to rank for target keywords and optimize content distribution strategies accordingly.
Examples
• An SEO specialist analyzes Page Authority scores across a client’s website to identify high-authority pages suitable for internal linking to boost weaker content
• A content marketing team uses Page Authority data to determine which blog posts should receive additional promotion and backlink building efforts for maximum SEO impact
• A web design agency explains Page Authority differences to clients when recommending site architecture changes that distribute link equity more effectively across important landing pages
