What is Page Authority?

Page Authority (PA) measures the ranking strength of individual pages rather than entire domains. Developed by Moz, PA predicts how well a specific URL will perform in search results based on its backlink profile and other factors. Higher PA generally correlates with better ranking potential.

Key differences: Page Authority measures single URL strength while Domain Authority measures entire website strength. PA focuses on specific page backlinks, while DA aggregates domain-wide signals. Both use 1-100 logarithmic scales. PA is useful for comparing individual content pieces.

Page Authority is influenced by: Number and quality of backlinks to the specific page, Link equity passed from high-authority sources, Relevance of linking pages, Internal linking structure, Age and history of the page, and Overall domain strength providing a baseline.

Apply PA for: Competitive analysis of specific ranking pages, Identifying link building priorities, Evaluating content performance over time, Comparing your pages to competitors, Assessing acquisition targets or guest post opportunities, and Understanding why pages rank differently.

Boost PA by: Earning quality backlinks to specific pages, Strategic internal linking from high-PA pages, Creating comprehensive link-worthy content, Building topical relevance through related content, Updating and refreshing older content, and Fixing broken links pointing to the page.
