Page Authority (PA)
Score predicting how well a specific page will rank in search results
Definition
Page Authority (PA) is a score developed by Moz (1-100 scale) that predicts how well a specific page will rank in search engine results. While Domain Authority scores an entire domain, PA scores individual pages based on factors like quality and quantity of backlinks to that page, on-page optimization, content quality, and overall link profile. PA is comparative—a page with PA 40 isn't inherently 'good' or 'bad,' but it's likely to outrank pages with PA 30 and struggle against PA 60. Higher PA pages pass more 'link juice' when they link to your content, making them valuable for backlink building. PA is useful for: comparing your page against competitors for target keywords, identifying high-value pages on your own site to leverage for internal linking, and prioritizing which pages to improve. Like DA, PA is a third-party metric not used by Google's algorithm, but it correlates with Google's evaluation of page strength.
Real-World Example
Analyzing the keyword 'AI marketing automation Singapore' shows: Position 1 (PA 52), Position 2 (PA 48), Position 3 (PA 45). Your page ranks #12 with PA 28. To compete, you need to build 15-20 quality backlinks to that page, add 2,000 words of comprehensive content with examples, and get internal links from your high-PA pages (like your homepage PA 42 and popular blog posts PA 35+). After 4 months implementing this strategy, PA rises to 43 and ranking improves to position 4.
