When you dive into SEO metrics, you will often see the abbreviation PA alongside DA. PA stands for Page Authority, a score that predicts how well a specific page, rather than an entire website, is likely to rank in search results. Understanding Page Authority helps you evaluate the strength of individual pages, prioritize your optimization efforts, and benchmark against competitors. In this article, we will explain what Page Authority is, how it is calculated, how it differs from Domain Authority, and the practical steps you can take to improve it.

What Is Page Authority?

Page Authority is a metric developed by the SEO company Moz that predicts how likely a single page is to rank in search engine results. Like Domain Authority, it uses a scale from 1 to 100, where higher scores indicate greater ranking potential. The difference is scope: while Domain Authority measures the strength of an entire domain, Page Authority focuses on one specific URL.

Because PA is page-specific, it lets you assess the individual strength of your homepage, a blog post, a product page, or any other URL. This granular view is useful for understanding which pages carry the most weight and which need more attention.

How Is Page Authority Calculated?

Page Authority is calculated using a range of factors, with the page's backlink profile playing a central role. The number of links pointing to the page, the quality and authority of those linking pages, and the overall relevance of the links all contribute to the score. Signals from the broader domain also influence PA, which is why pages on strong domains often start with an advantage.

Like Domain Authority, PA uses a logarithmic scale, so improving a score from 20 to 30 is easier than moving from 60 to 70. The metric is best used comparatively, helping you weigh one page against another or against competing pages in search results.

Page Authority Versus Domain Authority

Understanding the relationship between PA and DA is important. Domain Authority reflects the overall strength of your entire website, influenced by the collective link profile of all its pages. Page Authority zooms in on a single page. A website can have a high DA while individual pages have varying PA scores, depending on how many quality links each page has earned.

In practice, both metrics work together. A strong domain gives pages a helpful foundation, but each page still needs its own relevance, content quality, and links to reach its full ranking potential. Use DA to gauge your site's overall competitiveness and PA to evaluate and prioritize specific pages.

Why Page Authority Matters

Page Authority is a helpful benchmarking and prioritization tool. By comparing the PA of your pages, you can identify which ones are strongest and which need support. When targeting a competitive keyword, comparing your page's PA to competing pages gives you a rough sense of how much work may be required to compete.

It is worth remembering that PA, like DA, is a third-party metric and not a factor Google uses directly. It is an estimate of ranking potential, not a guarantee. Still, because it correlates with the signals that do matter, it offers useful guidance.

How to Improve Page Authority

Improving Page Authority comes down to strengthening the signals that make a page rank-worthy. The most impactful step is earning high-quality backlinks that point directly to the page. Links from relevant, authoritative sources carry the most weight, so focus on creating content that others want to reference and reaching out to build genuine connections.

Internal linking is another powerful lever. By linking to an important page from other relevant pages on your site, you pass authority to it and signal its importance. Improving the page's content quality, relevance, and on-page optimization also supports better performance and encourages more natural links.

Focus on the Fundamentals

Rather than obsessing over the PA number itself, concentrate on the underlying practices that improve it. Publish genuinely useful content, earn legitimate links, structure your internal linking thoughtfully, and maintain a technically sound site. When you focus on these fundamentals, both your Page Authority and your actual rankings tend to rise together.

Final Thoughts

Page Authority is a valuable metric for understanding the ranking potential of individual pages and prioritizing your SEO efforts. While it is not a direct Google ranking factor, the strategies that improve it, especially earning quality backlinks and strengthening content, are exactly what help pages rank.
