What is Page Authority PA? (A-Z Explanations)

Page Authority is a common and significant concept in Search Engine Optimization (SEO). In SEO Focus Point we have already discussed Domain Authority but today we will give in-depth explanations about Page Authority. This Article will cover, Definition of  Authority, Its impact on SEO, How it can be measured, and How to increase it, and so on. Let’s start our discussion.

Google doesn’t have any kind of ‘authority’ metric. Webmaster trends analyst John Mueller said,

“In general, Google doesn’t evaluate a site’s authority. So it’s not something where we would give you a score on authority and say this is the general score for authority on your website. That’s not something we would be applying here.”

It’s true Google has no connection with Page Authority(PA), Because this concept is developed by MOZ, not Google.

But Page Authority is measured based on several factors. It may be more than 40 factors are considered in calculating PA.

Interestingly, Google also considers those factors in SERP Ranking. So, it is clear that Google does not use the term but the determinants are the same. we will discuss those determinants in this article later on.

What is Page Authority(PA)?

Page Authority, an innovative metric developed by Moz, an industry-leading SEO software company, serves as a vital tool for predicting the potential ranking success of a specific web page on search engine results pages (SERPs). While many metrics exist, Page Authority stands out for its focus on individual web pages rather than entire domains, offering a more granular assessment.

The computation of Page Authority involves a multifaceted algorithm, which considers several key factors. A prominent aspect is link metrics, encompassing the quality and quantity of incoming links directed toward the page. Pages that receive numerous authoritative backlinks tend to attain higher Page Authority scores, indicating a stronger likelihood of securing favorable search engine rankings.

How Page Authority is measured or calculated

Moz has not yet disclosed the specific formula, of how they calculate PA but we are well-known about this matrics because about a dozen SEO Tools exist that also use this formula independently of their own.

However, It’s almost the same as Domain Authority but the only difference is PA is for the Specific web page of a domain, and Domain authority (DA) is for the root or entire domain.

Moz uses a 100-point logarithmic scale to measure PA. That means the score must be 0 to 100. They always update their algorithm. that’s why the score may fluctuate over time calculations. MOZ Link Explorer can give your page authority score in seconds. It is super easy just put your web page link here and click Get free Link Data.


Moz Link Explorer

Not only Moz dozens of other Tools provide this service with their own name, as we mentioned earlier. Most of them are as follows:

  1. Ahrefs Website “Authority” Checker
  2. Domain Authority Checker
  3. Semrush Domain Owerview
  4. Duplichecker

However, Moz calculates Page Authority (PA) by following determinants:

Link Profile

The “link profile” refers to the collection of all the inbound links (backlinks) that point to a specific website or web page from other websites on the internet. In other words, it represents the network of websites that are linking to the target website or page. The link profile is a crucial element in search engine optimization (SEO) and plays a significant role in determining a website’s or web page’s authority and visibility in search engine results.

The quality and quantity of the links in a website’s link profile are essential factors in assessing its authority and credibility in the eyes of search engines. A strong link profile typically includes:

  • High-Quality Backlinks
  • Relevant Links
  • Diverse Link Sources
  • Natural Link Building
  • Link Anchor Text

It’s important to note that while a strong link profile is beneficial for SEO, spammy or low-quality backlinks can harm a website’s search rankings. Search engines continuously evolve their algorithms to identify and penalize websites engaged in manipulative link-building practices.


MozRank is a proprietary metric developed by Moz, an SEO software company, to measure the authority or popularity of a web page on the internet. It is one of the several metrics offered by Moz to help assess a website’s or web page’s search engine optimization (SEO) performance.

The MozRank score is calculated based on the quantity and quality of links that point to a web page. Specifically, it focuses on the number of external links (backlinks) that a page receives from other websites and the authority of those linking pages.

The key points about MozRank are as follows:

  • Link-based Metric
  • Quality over Quantity
  • Logarithmic Scale
  • Updates and Variations
  • Relative Metric

MozRank can be used as a quick reference to gauge the link authority of a web page. However, it is crucial to consider it in conjunction with other SEO metrics and factors to get a comprehensive understanding of a page’s SEO performance. For a more complete analysis of a website’s authority, Moz also offers other metrics, such as Domain Authority (DA) and Page Authority (PA), which consider additional factors beyond just the link profile.


MozTrust is another proprietary metric developed by Moz, an SEO software company, to assess the trustworthiness and reliability of a website or web page. It is one of the several metrics provided by Moz to help SEO professionals and website owners gauge the credibility and trustworthiness of a domain or individual page.

The key characteristics of MozTrust are as follows:

  • Trust-based Metric
  • Quality Link Sources
  • Propagation of Trust
  • Logarithmic Scale
  • Relative Metric
  • Updates and Variations

MozTrust is a useful metric for assessing the trustworthiness of a website’s link profile. It can help website owners and SEO practitioners identify potential issues with low-quality or spammy backlinks that might negatively impact a page’s trustworthiness and search engine rankings.

Linking Root Domains

Linking Root Domains (LRDs) refer to the unique root domains that contain at least one backlink to a specific website or web page. In other words, when multiple links originate from the same root domain, they are counted as one linking root domain. LRDs are a significant metric in search engine optimization (SEO) as they are used to assess the diversity and quality of backlinks pointing to a website.

Here are some key points about Linking Root Domains:

  • Uniqueness
  • Authority and Diversity
  • Relevance

Content Quality and Relevance

While not explicitly stated in the formula, the relevance and quality of the content on the page are believed to play a role in Page Authority. Pages with valuable, well-optimized content are more likely to attract links and higher authority.

Social Signals

Social media mentions, shares and engagement related to the page’s content might also influence Page Authority indirectly. Popular and shareable content may attract more backlinks and enhance the page’s authority.

User Experience Metrics

While not directly considered in Page Authority, user experience metrics such as page load speed, mobile-friendliness, and overall website usability can indirectly impact the page’s ability to attract backlinks and influence its authority.

It is important to understand that these determinants are not an exhaustive list, and other factors might also play a role in Page Authority calculation. Additionally, the exact weight and interplay of these factors in the algorithm are proprietary information kept by Moz.

What is a good page authority(PA)?

PA is scored on a logarithmic scale from 0 to 100, with higher scores indicating a stronger potential to rank well in search engine results. While there is no fixed threshold for what constitutes a “good” Page Authority, here’s a general guideline:

good page authority

  • 0 – 20:    Low Authority
  • 21 – 40Moderate Authority
  • 41 – 60Reasonable Authority
  • 61 – 80Strong Authority
  • 81 – 100: Very Strong Authority

A good PA varies depending on factors like your industry, competition, and specific goals. Generally, aiming for a Page Authority score above 50 can be considered quite favorable, and achieving scores in the 60s or higher indicates a strong level of authority. Remember, Page Authority is a relative metric and should be interpreted within the context of your specific website and objectives.

Significance of Page Authority in SEO

The significance of PA in SEO cannot be overstated, as it plays a pivotal role in determining a webpage’s ability to rank well on search engine results pages (SERPs) and attract organic traffic. Page Authority, a metric developed by Moz, evaluates the authority and credibility of a specific webpage based on a variety of factors. Here are some key reasons why PA holds significant importance in the field of SEO:

  1. Improved Search Engine Ranking: Page Authority directly impacts a webpage’s ranking on search engines. Webpages with higher PA are more likely to appear at the top of search results, leading to increased visibility and click-through rates. This improved ranking enhances the chances of attracting organic traffic and potential customers.
  2. Credibility and Trust: High PA is often an indicator of a web page’s credibility and trustworthiness. Search engines, like Google, consider authoritative pages as reliable sources of information. Users are more likely to trust and engage with content from pages that have a higher PA, establishing a positive user experience.
  3. Competitive Edge: In a highly competitive online landscape, having a strong Page Authority can give websites a competitive advantage. Pages with higher authority are more likely to outrank their competitors, capturing a larger share of organic traffic and potential customers.
  4. Organic Traffic Potential: A higher Page Authority leads to increased visibility and better rankings, resulting in a higher likelihood of attracting organic traffic. This organic traffic is essential for sustainable online growth without solely relying on paid advertising.
  5. Link Building Opportunities: Webmasters, bloggers, and other content creators are more likely to link to pages with higher Page Authority. This presents opportunities for natural and quality backlink building, which is a crucial factor in SEO success.
  6. Optimized User Experience: Pages with high Page Authority are likely to have well-structured content, relevant information, and a seamless user experience. As a result, visitors are more likely to spend time on these pages, reducing bounce rates and increasing engagement metrics, which can positively impact SEO rankings.
  7. Long-Term SEO Benefits: Improving PA requires a focus on producing high-quality, valuable content and building a strong online presence. These efforts align with best SEO practices and contribute to long-term sustainability, making Page Authority growth an essential component of a comprehensive SEO strategy.
  8. Brand Authority and Recognition: Consistently producing authoritative and high-quality content can contribute to building a brand’s authority and recognition in its niche. This can lead to increased brand loyalty, higher conversion rates, and a positive impact on overall business goals.
  9. Algorithm Updates and Adaptability: Search engine algorithms are continuously evolving. By focusing on improving Page Authority, websites can adapt to algorithm changes more effectively and maintain their competitive edge in the ever-changing SEO landscape.

In conclusion, PA is a critical metric in SEO that directly influences a webpage’s search engine ranking, credibility, and overall online success. Websites that invest in enhancing their PA hrough strategic content creation, optimization, and link-building efforts are more likely to achieve sustained organic traffic growth and achieve their business objectives.

Differences between Page Authority and Domain Authority

PA and DA are both important metrics in the field of SEO, but they focus on different aspects of a website’s online presence. Understanding the distinction between these two metrics is crucial for implementing an effective SEO strategy. Here’s a comparison between PA and Domain Authority DA:

Aspect Page Authority (PA) Domain Authority (DA)
Definition Measures the likelihood of a single webpage ranking well in search results. Measures the overall strength and authority of an entire website domain.
Scope Assesses the authority of an individual webpage. Considers the collective authority of all pages within a domain.
Use Case Optimizing individual pages for better search engine rankings. Assessing the overall health and authority of a website.
Calculation Scored on a logarithmic scale from 0 to 100. Also scored on a logarithmic scale from 0 to 100.
Factors Considered Inbound links, social signals, content quality, and user engagement of a specific page. Inbound links to the entire domain, root domains, and overall website performance.
Example A blog post with high-quality backlinks, engagement, and valuable content. A website with many high-quality backlinks, engaging content, and a strong online presence.


This table provides a clear and concise comparison between Page Authority and Domain Authority, highlighting their definitions, scopes, use cases, calculation methods, factors considered, and examples.

Page Authority in Evolving SEO Landscape

PA continues to hold significant relevance in the ever-evolving landscape of Search Engine Optimization (SEO). As search engine algorithms become more sophisticated and user expectations evolve, understanding how Page Authority fits into this dynamic environment is essential. Here’s a look at the role of PA in the evolving SEO landscape:

  1. Algorithmic Updates and User Intent: Search engines are increasingly focused on understanding user intent and delivering the most relevant results. While factors like content quality, relevance, and user engagement remain crucial, PA provides a valuable signal about a page’s credibility and authority. As algorithms adapt to better interpret user intent, pages with higher PA are more likely to align with searchers’ needs, leading to sustained rankings.
  2. E-A-T and Expertise: Expertise, Authoritativeness, and Trustworthiness (E-A-T) have become pivotal in SEO. Page Authority contributes to the “A” and “T” components by indicating a page’s authority and trustworthiness. Pages with high PA are more likely to be recognized as authoritative sources, especially in niches where credibility is paramount, such as medical or financial content.
  3. Mobile-First Indexing: With the shift to mobile-first indexing, PA gains new dimensions. Mobile-friendly and responsive design, fast loading speeds, and a positive mobile user experience all contribute to higher PA. As more users access content on mobile devices, ensuring strong Page Authority on mobile versions of pages becomes crucial for SEO success.
  4. Voice Search and Featured Snippets: Voice search and featured snippets have changed the way users interact with search results. Pages with high PA have a better chance of being featured as a snippet or being selected as the voice search answer. As search engines rely on authoritative sources to provide concise information, improving PA can lead to better visibility in these new search paradigms.
  5. User Experience and Core Web Vitals: User experience is increasingly tied to SEO performance. Google’s Core Web Vitals, which measure aspects of user experience such as page loading speed and interactivity, impact Page Authority. Sites that prioritize user experience and optimize their Core Web Vitals are likely to see improvements in Page Authority, leading to better rankings.
  6. Content Format Diversification: The SEO landscape has expanded beyond traditional text-based content. Videos, infographics, podcasts, and interactive content now play a role in ranking. Pages with high Page Authority can leverage their credibility to create and promote diverse content formats, enhancing their overall SEO strategy.
  7. User-Centric Metrics: Search engines increasingly consider user-centric metrics, including click-through rates, dwell time, and bounce rates, to evaluate page quality. Pages with high Page Authority are more likely to attract clicks, engage users, and reduce bounce rates, thereby signaling their relevance and authority to search engines.
  8. Machine Learning and AI: Machine learning and artificial intelligence are shaping how search engines understand and rank content. Page Authority, being a reflection of authority and quality, aligns with these advancements. Pages with high PA are better positioned to benefit from the evolving capabilities of AI-driven algorithms.

In conclusion, Page Authority remains a crucial metric in the evolving SEO landscape. As search engines refine their algorithms to prioritize user intent, expertise, and user experience, PA continues to serve as a strong indicator of a page’s credibility and authority. Adapting SEO strategies to enhance Page Authority can lead to improved rankings, better visibility, and sustainable organic traffic growth in today’s dynamic digital environment.

Common Misconceptions about Page Authority

There are several common misconceptions about Page Authority that can sometimes lead to misunderstandings or misinformed decisions in the field of SEO. Here are some of these misconceptions and clarification of each:

  1. Misconception: Page Authority is the only factor that determines search engine rankings.
    • Clarification: While PA is an important metric, search engine rankings are influenced by a multitude of factors, including content quality, relevancy, user experience, backlinks, technical SEO, and more. It is just one piece of the larger SEO puzzle.
  2. Misconception: Page Authority and PageRank are the same thing.
    • Clarification: PA and PageRank are distinct metrics. PageRank was Google’s original algorithm for ranking web pages, while Page Authority, developed by Moz, is a similar concept but calculated using different factors. PageRank is no longer publicly updated, and modern search engines use more complex algorithms.
  3. Misconception: Page Authority is the only measure of a page’s quality.
    • Clarification: PA primarily evaluates the authority and potential for ranking, but it doesn’t directly assess content quality, user engagement, or other qualitative factors. High PA doesn’t guarantee valuable or relevant content.
  4. Misconception: Page Authority is determined solely by the number of backlinks.
    • Clarification: While backlinks are a significant factor in Page Authority calculation, their quality, relevance, and diversity are equally important. A few high-quality, relevant backlinks can have a more positive impact than a larger number of low-quality ones.
  5. Misconception: Page Authority doesn’t change over time.
    • Clarification: PA can change over time based on various factors, including changes in the link profile, updates to the page’s content, algorithmic shifts, and the overall competitive landscape. Regular monitoring and improvements can lead to changes in Page Authority.
  6. Misconception: Page Authority is a direct ranking factor used by search engines.
    • Clarification: PA is a third-party metric developed by Moz and is not used directly by search engines like Google in their ranking algorithms. While it correlates with how a page might perform in search results, it’s not the exact factor search engines use.
  7. Misconception: Page Authority can be manipulated easily.
    • Clarification: Attempting to manipulate Page Authority through unethical or spammy practices, such as buying low-quality backlinks, can lead to penalties from search engines. Genuine improvements require a holistic and sustainable SEO strategy.
  8. Misconception: Page Authority is the same across all search engines.
    • Clarification: PA is specific to Moz’s metrics and doesn’t directly translate to how pages are ranked on different search engines like Google, Bing, or others. Different search engines have their own algorithms and criteria for ranking.
  9. Misconception: Pages with high Page Authority are guaranteed to rank first.
    • Clarification: While higher PA increases the likelihood of ranking well, it’s not a guarantee of the top position. Search engine rankings consider a variety of factors, and even pages with lower PA can outrank others due to superior content and other optimization efforts.
  10. Misconception: Page Authority is the most important metric in SEO.
    • Clarification: SEO success depends on a combination of factors, and while Page Authority is important, it should be considered alongside other metrics like Domain Authority, content quality, user experience, and technical SEO.

Understanding these misconceptions helps SEO practitioners make more informed decisions and develop effective strategies that consider the broader context of website optimization and search engine rankings.
