What Is Domain Authority And Page Authority & Why Does It Matter?


Table of Contents

You’ve probably heard of Domain Authority and Page Authority before. These are terms that Moz uses for different purposes.

Certain companies use DA to study and evaluate how well they’re performing in their strategies. It’s a qualitative measure of your website and how good it is at helping search engines rank websites higher than others in the search results.

This is why most SEO experts concentrate on developing quality and valuable content, link building, and other SEO techniques to increase their authority.

Authority is a strong signal of your overall Search Engine Optimization (SEO) performance. It isn’t the only technique to ensure that your web properties will rank and be visible in search results – you also need appropriate context based on the search query.

DA and PA are two popular authority metrics that are sometimes used interchangeably but differ. So what do these metrics ultimately mean? And what are their critical distinctions from one another?

In this article, we will define DA and PA and their functions so that you can better understand the main difference between them.

What Is Domain Authority?

Domain Authority (DA) is a metric developed by Moz, a leading SEO (Search Engine Optimization) software company, to measure the authority and credibility of a website.

It is a numeric score that ranges from 1 to 100 and is used to predict how well a website will rank on search engine result pages (SERPs).

The higher the score, the greater the chances of the website appearing at the top of the search engine results.

One important thing to remember is that DA is not a ranking factor used by search engines like Google but rather a third-party metric.

 However, it is still considered an important factor when evaluating a website’s overall strength and its potential for ranking well in search results.

Characteristics Of A Good DA Score

A good DA (Domain Authority) score is crucial to any website’s search engine optimization (SEO) strategy. DA score is a metric developed by MOZ, which predicts how well a website will rank on search engines. A higher DA score means your website has a better chance of ranking higher on search engine results pages (SERPs) for relevant keywords.

So, what are the characteristics of a good DA score?

  1. Relevance: A good DA score indicates that your website is relevant to your niche and industry. A relevant website is more likely to attract relevant traffic, leading to higher engagement, more conversions, and better search engine rankings.
  2. Quality of Backlinks: The quality of backlinks to your website is critical in determining your DA score. High-quality backlinks from authoritative websites in your niche will help to improve your DA score. Conversely, low-quality backlinks from irrelevant or spammy websites can harm your score.
  3. Content Quality: The quality of content on your website is another critical factor in determining your DA score. High-quality content that provides value to your audience will improve your DA score and encourage users to spend more time on your website and share your content with others.
  4. User Experience: A good DA score indicates that your website provides a positive user experience. A website that is easy to navigate has a clear and concise design and is optimized for desktop, and mobile devices will have a higher DA score.
  5. Consistency: A good DA score requires content quality and backlink-building consistency. It would be best if you aimed to produce high-quality content regularly and obtain high-quality backlinks consistently.

How is your DA calculated?

How DA Is Calculated

Multiple factors, such as the number and quality of backlinks to a website, the age of the domain, the content on the website, and other technical SEO elements, calculate the DA score.

Backlinks, also known as inbound links, link from other websites to a specific page on your website. Search engines consider backlinks a “vote of confidence” in the quality and relevance of your website, and a large number of high-quality backlinks can improve your DA score.

How To Check Your Website DA?

You can check your website’s DA for free using tools like Ahrefs’s Backlink Checker or Moz Link Explorer. Enter the root URL of the domain into these tools, which will calculate and display your website’s DA.

How To Increase Your DA?

Here are some tips to help you increase your Domain Authority (DA):

  1. Publish high-quality, original content: Content is the backbone of a successful website, and it is essential to publish high-quality content relevant to your target audience.
  2. Optimize your content for search engines: Optimize your content using keywords and meta tags to help search engines understand what your content is about and rank it higher in search results.
  3. Acquire backlinks from high-authority websites: Backlinks from high-authority websites are essential for improving your DA. Try to get backlinks from reputable sources such as government websites, educational institutions, and well-established businesses.
  4. Improve your website’s user experience: Make sure your website is easy to navigate, has a clean design, and loads quickly. This will improve the user experience and encourage visitors to spend more time on your site.
  5. Engage with your audience: Engage with your audience by responding to comments and feedback and sharing your content on social media. This will help you build a community of loyal followers and increase your visibility.
  6. Monitor your website’s performance: Use tools such as Google Analytics to monitor your website’s performance and identify areas for improvement. This will help you understand how visitors interact with your site and make changes to improve your DA.
  7. Stay updated with industry trends: Keep up to date by reading blogs, attending conferences, and networking with other professionals. This will help you stay ahead of the curve and ensure that your website remains relevant.

Remember, increasing your DA takes time and effort, but following these tips will help you make significant progress.

What Is Page Authority?

Page Authority is a metric that measures the strength of a particular page on a website regarding its ability to rank on search engine result pages (SERPs).

It predicts how well a specific page is likely to rank on search engine results based on various factors such as the quality and relevance of its content, the number and quality of external links pointing to it, and its overall popularity on the web. In other words, Page Authority indicates the strength of a page compared to all other pages on the web.

Developed by Moz, Page Authority is an essential metric for website owners and marketers to understand the performance of their particular page.

A high Page Authority score means a page is more likely to rank well on search engines, which can drive more organic traffic to the website. On the other hand, a low Page Authority score indicates that the page may need help ranking for specific keywords, which could result in lower visibility and fewer organic visitors.

Characteristics Of A Good PA Score?

Here are some characteristics of a good Page Authority score:

  1. Relevance: A high PA score usually indicates a website relevant to its target audience and provides valuable information and resources. This relevance is reflected in the number of high-quality, inbound links that point to the site.
  2. Strong Backlink Profile: A strong backlink profile is one of the critical factors in determining a high PA score. Websites with high-quality, inbound links are likelier to have a high PA score.
  3. Regular Content Updates: Websites that regularly update their content with fresh, relevant, and high-quality information are likelier to have a high PA score. This shows that the site is active and relevant, which is a critical factor in determining PA.
  4. User Engagement: Websites with high levels of user engagement, such as those with many comments, social shares, and return visitors, are more likely to have a high PA score. This indicates that the site provides valuable information and resources that users find helpful.
  5. Mobile-Friendly Design: With the growing use of mobile devices to access the internet, websites must have a mobile-friendly design. Websites optimized for mobile devices are more likely to have a high PA score, as they provide a positive user experience for mobile users.

How is your PA calculated?

Page Authority is determined by several factors, including the quality and relevance of the content on the page, the number and quality of external links pointing to it, and the website’s overall popularity.

For example, a page with high-quality content and many high-authority external links is likely to have a high Page Authority score. In contrast, a page with low-quality content and few external links will likely have a lower score.

How To Check Your PA?

There are a few ways to check the page authority of a webpage:

  • Moz: Moz offers a free tool called Open Site Explorer, which provides a page authority score and other important metrics like Domain Authority and backlinks.
  • Ahrefs: Ahrefs is a paid tool that provides a “URL Rating” that reflects the authority of a particular page.
  • Majestic: Majestic is another paid tool that provides a “Trust Flow” metric similar to page authority.
  • SEMrush: SEMrush is a paid SEO and marketing tool that provides a “Page Score” metric based on a combination of factors such as backlinks, organic search traffic, and other factors.

Note that these metrics are not absolute and can fluctuate, but they help compare the relative authority of different pages. Additionally, these metrics are just one of many factors that search engines use to rank pages, so while they can be valuable indicators of a page’s potential to rank well, they should not be the sole focus of your SEO efforts.

How To Increase Your PA?

While you can’t control PAs and rank in the SERPs, you can take some steps to increase the likelihood of a high PA and a higher ranking on the SERPs.

Here are some of the most important steps to follow:

  • To optimize your pages, focus on building direct links to them. Effective link-building should take place at the page level, where you can concentrate on producing high-quality, authoritative, and in-depth content to engage your audience.
  • Distribute the page authority throughout your website, and consider linking pages with less PA to those with higher PA, ensuring that the links are contextually relevant to the topic.
  • Ensure that each page is packed with valuable and unique content that is comprehensive and covers all aspects of the topic.
  • To boost your domain authority, utilize the tips discussed above and ensure your website has a clean URL structure and is optimized for search engines.
  • Eliminate harmful links to your pages, as they can undermine all your efforts and lead to a lower ranking or even a Google penalty.
  • To request the removal of such links, use Google’s disavow tool.
  • Creating a page on a high-authority domain and optimizing it for SEO and functionality will also contribute to boosting your page ranking.

What is the difference Between Domain Authority VS Page Authority?


Domain Authority (DA): To predict the overall ranking of a website’s domain.

Page Authority (PA): To predict the ranking potential of an individual page within a website.


Domain Authority (DA): DA considers multiple factors, such as the quantity and quality of links pointing to the website, the age of the domain, and the popularity of the website.

Page Authority (PA): PA considers multiple factors, such as the quantity and quality of links pointing to the page, the content quality and relevance of the page, and the internal linking structure of the website.


MOZ calculates Domain Authority using a machine learning-powered algorithm that assesses the linking root domains and the number of links on your website. The score is then determined and ranges from 1 to 100, allowing you to track your website’s ranking strength compared to your competition.

Similarly, Page Authority is calculated using an algorithm that considers factors such as link counts to determine a score ranging from 1 to 100 for an individual page within your website.”


Domain Authority (DA): DA measures a website’s ranking potential as a whole and can be used to compare the relative ranking potential of different websites.

Page Authority (PA): PA measures the ranking potential of an individual page within a website and can be used to compare the relative ranking potential of different pages within a website.

Wrapping Up
