What is Page Authority?

Page Authority (PA) is a score from 1 to 100 that predicts how well a specific page will rank in search results. Created by Moz, it measures the ranking potential of individual pages rather than entire domains.

PA is calculated based on the backlinks pointing to that specific page, the quality of those links, and other factors. A single page on a low-authority site can have high PA if it has strong backlinks.

Why page authority matters

Page Authority helps you understand which of your pages are strongest from an SEO perspective. You can use this to identify which pages to prioritize for internal linking or which competitors will be hardest to outrank.

When evaluating whether you can rank for a keyword, look at the PA of currently ranking pages. If the top results all have PA above 50 and your page has PA 15, you'll need to build links or target a less competitive keyword.

Page Authority vs Domain Authority

Domain Authority measures your entire site's strength, while Page Authority measures individual pages. You can have a high-DA site with low-PA pages if those pages lack focused links or quality content.

A page can have higher PA than your overall DA if it's earned particularly strong backlinks. This is common with viral content or comprehensive guides that many sites reference.

How to Improve It

Build backlinks directly to the page you want to rank. Guest posts, mentions, and references that link to that specific URL will boost its PA.

Use internal links to pass link juice from your stronger pages to weaker ones. This helps distribute authority throughout your site.

Create content worth linking to. Comprehensive, well-researched posts naturally attract more backlinks than thin or generic content. Focus on quality first, then promote strategically.
