What is Page Authority? A Practical Guide for SEO
Learn what Page Authority (PA) is, how it's calculated on a logarithmic scale, and how to use this metric to improve your specific webpage rankings.
Page Authority (PA) is a predictive metric, originally developed by Moz, that estimates how well a specific URL will rank on search engine result pages (SERPs). Scored on a logarithmic scale from 1 to 100, it focuses exclusively on the strength of an individual page rather than the entire domain. High PA scores suggest a greater potential to compete for difficult keywords, primarily driven by the quality and quantity of external backlinks pointing to that specific page.
Key Takeaways
- ✓PA measures the ranking strength of a single URL, not an entire website.
- ✓The 1-100 scale is logarithmic, making it harder to move from 70 to 80 than 10 to 20.
- ✓It is a comparative tool for benchmarking against competitors, not a direct Google ranking factor.
- ✓Backlink profile quality is the primary driver of Page Authority.

How to Approach
Analyze Current Page Strength
Use SEO tools to pull the PA of your target URL and compare it against the top 10 results for your primary keyword.
AI Insight: AI-driven analysis can highlight if a ranking gap is due to authority (links) or content relevance (keywords).
Audit the Backlink Profile
Examine the number of unique linking root domains and the 'equity' those links pass to your page.
AI Insight: Focusing on high-authority, niche-relevant referring domains often yields better PA growth than high-volume, low-quality links.
Optimize Internal Linking
Distribute 'link juice' from your site's highest-PA pages to lower-performing pages via strategic internal links.
AI Insight: Automated crawlers can identify 'orphan pages' with 0 PA that are currently invisible to search engines.
Common Challenges
Stagnant PA scores despite adding new content.
Why This Happens
Shift focus from content volume to external link acquisition and improving internal link architecture.
Solution
Incorporate a 'linkable asset' strategy into your content creation process to naturally attract backlinks.
Difficulty interpreting the logarithmic scale.
Why This Happens
Use PA as a relative metric (benchmarking) rather than an absolute goal.
Solution
Set goals based on closing the gap with specific competitors rather than reaching a specific number.
