Page Authority (PA) is Moz's proprietary metric that predicts how well a specific page will rank in search results—scored from 1-100 based on link profile strength, content quality, and other ranking factors, useful for competitive analysis and SEO planning.
What is Page Authority?
Think of it like a credibility score for individual pages rather than entire websites—Page Authority evaluates the ranking potential of specific pages based on their backlink profiles, internal link support, and content quality. While not an official Google metric, PA correlates with actual search performance and helps assess competitive landscapes.
When You Need to Consider Page Authority
- Analyzing why competitor pages outrank yours for specific keywords
- Evaluating which of your own pages have the strongest ranking potential
- Planning internal linking strategies to boost important page authority
- Assessing the difficulty of ranking for specific search terms
- Measuring the impact of link building efforts on individual pages
Need help building page authority for your most important business pages? Our SEO strategy includes targeted link building and internal optimization to strengthen individual page rankings.
Real-World Example
Low page authority: Your accounting services page has PA 25 with few backlinks, while competitor's similar page has PA 55 with strong link profile
Strategic page authority building: Through targeted link building and internal linking, your page authority increases to PA 45, improving search rankings for target keywords
- Without page authority focus: Individual pages struggle to rank despite good content, losing to competitors with stronger page-level authority.
- With strategic building: Higher page authority supports better rankings and increased organic visibility for target keywords.
Business Impact
Better Individual Page Rankings
Higher page authority directly correlates with improved search rankings for specific pages targeting valuable keywords.
Competitive Analysis Insights
PA scores help identify why competitors rank better and what authority levels you need to achieve for competitive success.
Strategic Resource Allocation
Understanding page authority helps prioritize which pages deserve additional link building or optimization investment.
Red Flag to Watch For
Some Singapore SEO agencies focus only on domain authority without considering individual page strength, missing opportunities to boost specific high-value pages. Others may chase PA numbers without ensuring the metrics translate to actual business results.
