What Is Page Authority (PA)

7 Min Read

When people talk about SEO, they often focus on website rankings, backlinks, and organic traffic. However, understanding the strength of individual pages is just as important. This is where Page Authority (PA) comes into play.

Page Authority is a popular SEO metric used to estimate how well a specific webpage is likely to rank in search engine results. It helps marketers, bloggers, businesses, and SEO professionals evaluate the ranking potential of individual pages and identify areas for improvement.

While Page Authority is not a direct Google ranking factor, it can be a useful indicator of a page’s overall SEO strength.

In this guide, you’ll learn what Page Authority is, how it works, why it matters, and how to improve it for better search visibility.

What Is Page Authority?

Page Authority (PA) is a score developed by Moz that predicts the likelihood of a specific webpage ranking in search engine results.

The score ranges from 1 to 100.

A higher score generally indicates a stronger page with a better chance of competing for search rankings.

Unlike Domain Authority, which measures the strength of an entire website, Page Authority focuses on a single page.

Example

Imagine your website has:

Homepage.
SEO Services Page.
Blog Post About SEO Tips.
Contact Page.

Each page can have a different Page Authority score based on its backlinks, content quality, and overall SEO signals.

Why Is Page Authority Important?

Page Authority helps website owners understand which pages have the greatest ranking potential.

It provides useful insights for SEO planning and content optimization.

Benefits of Page Authority

1. Measures Page Strength

Page Authority helps determine how strong a specific webpage is in terms of SEO. It gives an estimate of the page’s ability to rank in search engine results based on factors like backlinks and overall authority.

2. Supports SEO Analysis

PA allows you to identify pages that are performing well and those that need improvement. By analyzing these scores, you can make better SEO decisions and optimize pages for higher rankings.

3. Helps Compare Competitors

Comparing the Page Authority of your pages with competitors helps you understand the level of competition. It also reveals how much effort may be needed to outrank similar pages in search results.

4. Guides Link-Building Efforts

Pages with higher Page Authority often have strong and quality backlinks. Tracking PA can help you focus your link-building efforts on pages that need more authority and visibility.

5. Tracks SEO Growth

Monitoring Page Authority over time helps measure the impact of your SEO strategies. An increase in PA may indicate improvements in content quality, backlink profile, and overall page performance.

How Is Page Authority Calculated?

Page Authority is based on several SEO factors.

Some of the most important include:

Number of backlinks.
Quality of backlinks.
Relevance of linking websites.
Link diversity.
Page trust signals.
Overall backlink profile.

Moz uses machine learning models to estimate a page’s ranking potential.

Because the algorithm is constantly updated, PA scores can change over time.

What Is a Good Page Authority Score?

There is no universal “perfect” score.

The right PA score depends on your niche and competition.

General PA Score Guide

PA Score	Authority Level
1 – 20	Low
21 – 40	Average
41 – 60	Good
61 – 80	Strong
81 – 100	Excellent

A page with a PA of 35 may perform very well in a low-competition niche, while a highly competitive industry may require a much higher score.

Page Authority vs Domain Authority

Many beginners confuse Page Authority and Domain Authority because both measure website strength. However, Page Authority evaluates the ranking potential of a single webpage, while Domain Authority measures the overall authority of an entire website.

Page Authority (PA)

Measures a single webpage.
Evaluates page-specific ranking potential.
Influenced by backlinks pointing to that page.
Helps assess individual content performance.

Domain Authority (DA)

Measures the entire website.
Evaluates overall domain strength.
Influenced by domain-wide backlinks.
Helps assess website-level authority.

Comparison Table

Page Authority	Domain Authority
Measures the authority of a single webpage.	Focuses on the whole domain.
Measures page-level ranking potential.	Measures domain-level ranking potential.
Affects individual content performance.	Reflects overall website authority.
Influenced by page-specific links.	Influenced by domain-wide links.

Both metrics are useful, but they serve different purposes.

Factors That Influence Page Authority

Several factors influence a page’s authority score and determine its ranking potential in search results.

High-Quality Backlinks

Backlinks remain one of the strongest factors affecting Page Authority.

Links from trustworthy and relevant websites can significantly improve a page’s strength.

Content Quality

High-quality content provides accurate, useful, and original information that meets user needs. Pages with valuable content are more likely to attract backlinks, increase engagement, and perform better in search results.

Internal Links

Internal links connect different pages within your website and help users navigate easily. They also help search engines understand your site structure and distribute authority across important pages.

User Experience

A good user experience ensures visitors can access information quickly and easily. Fast-loading pages, mobile-friendly designs, and clear navigation can improve engagement and reduce bounce rates.

Link Relevance

Relevant backlinks come from websites or pages related to your industry or topic. These links are often more valuable because they provide stronger context and credibility to search engines.

Content Freshness

Fresh content stays updated with the latest information, trends, and user needs. Regular updates can improve relevance, maintain rankings, and encourage more visitors to return to your website.

How to Improve Page Authority

Improving Page Authority takes time and requires ongoing SEO work. By creating valuable content, earning quality backlinks, and optimizing your pages, you can gradually increase your page’s authority and ranking potential.

Resource page outreach.
Broken link building.

Common Page Authority Mistakes

Chasing Scores Instead of Results

Many website owners focus only on increasing their Page Authority score. While PA is useful, real success comes from gaining organic traffic, generating leads, and improving user engagement.

Buying Backlinks

Buying backlinks may seem like a quick way to boost authority, but it can violate search engine guidelines. Low-quality paid links can harm your website’s reputation and SEO performance over time.

Ignoring Content Quality

Content is one of the most important factors for long-term SEO success. Even if a page has strong backlinks, poor-quality content can reduce user trust and limit ranking potential.

Building Low-Quality Links

Not all backlinks provide value. Links from spammy or irrelevant websites can weaken your backlink profile and negatively affect your page’s credibility.

Neglecting Internal Linking

Internal links help search engines understand the relationship between pages on your website. A strong internal linking strategy can improve page visibility and distribute authority more effectively.

Does Google Use Page Authority?

No.

Google does not use Moz’s Page Authority score as a ranking factor.

PA is a third-party metric designed to estimate ranking potential.

However, many factors that improve Page Authority—such as quality content, backlinks, and user experience, are also important for search engine rankings.

Why Page Authority Matters for Content Marketing

Page Authority can help content creators identify which pages have the best opportunity to rank and attract traffic.

By improving the authority of important pages, businesses can:

Increase organic traffic.
Improve keyword rankings.
Generate more leads.
Build credibility.
Strengthen online visibility.

A strong page often becomes a valuable long-term asset for a website.

Conclusion

Page Authority is a useful SEO metric that measures the ranking potential of individual webpages. Although it is not used directly by Google, it provides valuable insights into page strength, backlink quality, and overall SEO performance.

The best way to improve Page Authority is to focus on creating valuable content, earning quality backlinks, strengthening internal links, and maintaining a great user experience.

Rather than chasing a specific number, concentrate on building pages that genuinely help users. Over time, strong SEO practices often lead to higher authority, better rankings, and sustainable organic growth.
