Page Authority: What is it? What is it for? How to measure it?


Page authority is another SEO metric to take into account for website analysis and your media selection campaign for linkbuilding.

SEO metrics are the tools you should use to determine the authority and relevance of a specific page on the internet. Page authority is another metric that determines this rating, and in this article, we are going to explain why you have to take this tool into account for your link-building campaign.

What is Page authority?

Page authority, known as PA, is a metric developed by MOZ, a well-known SEO software company. This metric assigns a score from 1 to 100 to a web page based on its likelihood of ranking in search engines. The higher the score, the higher the perceived authority and relevance of that particular page.

This calculation is based on a variety of factors but mainly focuses on the quality and quantity of backlinks pointing to the page in question. MOZ uses its database of backlinks and algorithms to assess link strength and generate a representative score.

What is the purpose of the PA?

It’s an important metric that provides valuable insights into a page’s ability to rank in search engines. Each metric stands out for assigning a rating based on a specific characteristic of the websites; some analyze the domains, others the quality of the content, and in the case of the AP, it analyzes everything that encompasses the authority and quality of the page as such. Below are some of its main features.

It is developed by MOZ

MOZ is a leading company in the field of SEO, and its metrics tool is widely used and respected in the industry. Page authority is a reliable SEO metric that allows you to quickly assess the quality and relevance of a page based on its score.

SEO metrics are critical to link building strategies

Link building, or getting quality inbound links, is an essential strategy in SEO. Page authority helps you identify the most valuable and authoritative pages for linking. By focusing on pages with a high rating, you increase the likelihood that the links will be valuable and beneficial to your optimization strategy.

How is Page authority measured?

Measuring Page Authority involves specific tools, such as MOZ’s Page Authority Checker. This tool allows you to enter the URL of a page and get its score instantly.

It’s based on a logarithmic score model from 1 to 100, which means it’s easier to increase BP from 20 to 30 than from 70 to 80. This is because each additional point on the scale requires a significantly greater increase in the quality and quantity of backlinks.

By using the Page Authority Checker, you can evaluate the Page Authority of your website and your competitors. This gives you a clear perspective of how your page compares in terms of authority and helps you identify opportunities for improvement.

Differences from other metrics

Other similar metrics are often confused with each other. Below, we’ll look at the differences between page authority, domain authority, and domain rating.

Differences with Domain Authority

Domain authority, or DA, is another metric developed by MOZ. Unlike page authority, which evaluates the authority of a specific page, domain authority evaluates the authority of the entire domain or website in general. The DA takes into account various factors, including backlinks and site structure, to provide a domain-level authority score. While page authority is most useful for evaluating individual pages, domain authority is useful for evaluating the potential of the entire website in search engines.

Differences with Domain Rating

On the other hand, the Domain rating or DA is a metric developed by Ahrefs, another leading company in SEO tools. Like MOZ’s domain authority, the domain rating evaluates the authority of the entire domain. Both metrics have a similar approach and are based on factors such as backlinks.

The difference lies mainly in the data sources and algorithms used to calculate the scores. While both metrics are useful for assessing a domain’s authority, it’s important to note that they are metrics specific to each tool and can differ in their results.
