Page authority, often called PA, is a metric representing the potential for a page to rank compared to other content on a similar topic. It’s created and managed by leading SEO software provider Moz. Like other independent tool metrics, it isn’t tracked by Google and doesn’t have any direct impact on rankings.

Similar to Moz’s Domain Authority metric, Page Authority is scored on a 0-100 logarithmic scale. The higher the score, the more likely a page is to rank for relevant search terms. Moz calculates a page’s PR by looking at a number of different factors, including the number of unique referring domains a page has in its backlink profile, its dofollow backlinks, nofollow backlinks, redirects, the age of links in its backlink profile, and various other factors the company doesn’t disclose in detail.

A page authority rank between 40 and 50 is generally considered average, with any score of 51 or higher considered good. Having said that, page authority averages vary greatly depending on the content topic. To get an accurate idea of an average PA, you’ll need to look at the relevant SERP and the kind of scores that competitor content has.

To determine what kind of PA you should be aiming for for a specific piece of content, you can enter competitor pieces’ URLs into Moz’s free domain analysis tool.

Page authority can be useful for SEOs when weighing up the potential equity that a backlink from a referring page could bring in, or when comparing the potential value of a link from two different places within the same referring domain.

Both Page Authority and Domain Authority are based on data within the Mozscape index, which is gathered by bots designed to replicate the behaviour of Google’s web crawlers.

Because Page Authority is drawn from a wide range of different factors, there’s no catch-all solution for SEOs who want to improve their page authority score. The general advice is to make your whole site as SEO friendly as possible, by ensuring a smooth user experience, publishing high-quality content, and making it easy for crawlers to find your most important pages. Having said that, building backlinks from high quality, authoritative sources is the fastest and most reliable way to increase page rank.

Moz Page Authority (PA) FAQs

What is the difference between Domain Authority and Page Authority?

Domain authority measures the potential ranking strength of a whole domain or subdomain, whereas page authority only measures the strength of a specific page. However, there’s often a strong correlation between high domain authority and high page authority.
