But what exactly do these terms mean, and how do they impact your website’s visibility in search engine results? This is what we are going to answer in this guide. Read below as we discuss their definitions, differences, and significance in the world of SEO.

If you want to use the domain and page authority to your advantage and improve your SEO efforts, read this detailed guide, where we discuss the detailed definitions, differences, and the factors affecting the domain authority and page authority. Also, read about some common myths related to both of these metrics and how to use different tools to improve these metrics for your website.

Understanding Domain Authority

Developed by Moz, a leading SEO software provider, domain authority is a metric that tells us how likely a website is to rank higher in search engine results. 

Domain authority is actually a numerical score ranging from 1 to 100 that predicts the performance of a website in search engine rankings. The higher the domain authority score, the greater the potential for the website to rank well in search results. 

This authority is calculated with the help of a complex algorithm that takes into account various factors, including the number and quality of backlinks pointing to a website, the overall trustworthiness of the domain, and the website’s overall SEO performance. 


Factors Influencing Domain Authority


Several key factors influence a website’s domain authority score. Understanding these factors can help you improve your website’s overall authority and visibility in search engine results. Here are some of the main factors: 


  • Relevance of Content

Search engines value content that aligns with user intent and provides valuable information. Creating high-quality, relevant, and engaging content is essential for improving your domain authority. Valuable content attracts more backlinks and signals to search engines that your website is a reliable source of information, thereby increased PA and DA

Moreover, be sure to regularly update and refresh your content to help you stay relevant and authoritative. When creating and updating content, follow Google’s E.E.A.T guidelines

  • Quality of Backlinks

The quality of backlinks from other websites to yours significantly impacts your domain authority. High-quality backlinks from authoritative, relevant sources carry more weight than numerous links from less reputable sites. 

You can leverage strategies like guest posting, influencer outreach, and content marketing to build quality backlinks. This approach will need a robust link-building strategy focusing on acquiring high-quality backlinks from authoritative websites within your niche.

  • Website Age and Domain History

Established domains with a track record of consistent, positive performance may have higher authority. However, newer domains can still build authority over time through strategic SEO efforts. 

Focus on building a positive domain history by consistently delivering high-quality content, maintaining a clean backlink profile, and adhering to SEO best practices. This factor is what distinguishes domain authority vs page authority


  • Social Signals

Social media engagement and shares can indirectly influence your domain authority. When your content is shared and discussed on social media platforms, it can attract more traffic and potentially generate more backlinks. 

While not a direct ranking factor, social signals can boost your content’s reach and indirectly contribute to your domain’s authority. 


  • Technical SEO

Optimizing technical aspects of your website, such as meta tags, headers, site speed, and mobile optimization can contribute to a higher domain authority. A technically sound website is more likely to rank well in search engine results.

After understanding all these aspects, it is important to know that domain authority is not a ranking factor used by search engines like Google. Moz itself says that domain authority score is not a Google ranking factor and has no impact on the search engine results pages (SERPs). 


Understanding Page Authority

While domain authority measures the overall strength and credibility of a website, Page Authority (PA) focuses on the authority of individual web pages on that website. Let’s first see what does page authority mean

Also developed by Moz, page authority is a metric that predicts how likely an individual webpage is to rank in search engine results. Just like domain authority, page authority is scored on a scale of 1 to 100, with higher scores indicating a greater potential for ranking higher in search results.


Factors Influencing Page Authority Score 


  • Quality and Relevance of Content 

High-quality and relevant content is very important to increase the authority of a specific page on your website. Creating valuable, informative, and engaging content that meets the needs of your target audience and follows Google’s content guidelines can help improve the authority of your pages. 


  • Internal and External Linking

The way a web page is linked internally within your website and externally from other websites can impact its page authority. Internal links help search engines understand the structure of your website, while external links to reputable and authoritative websites can boost the authority of your page. 


  • User Experience and Engagement

User experience signals, such as the time spent on a page, bounce rate, and click-through rate, can influence Page Authority. A positive user experience, including fast page load times, easy navigation, and engaging design, can contribute to higher page authority. 


  • One-Page SEO Factors

Optimizing on-page elements, such as meta tags, headers, keyword usage, and URL structure, can contribute to higher page authority. Ensuring that your web page is optimized for relevant keywords and follows SEO best practices can improve its SEO page authority

One-Page SEO Factors

By focusing on these factors and implementing effective SEO strategies, you can enhance the page authority of your individual web pages and increase their visibility in search engine rankings. 

It is important to understand that both metrics work together to determine the overall strength and credibility of your website in search engine rankings. 


Difference Between Page Authority and Domain Authority

The main difference of domain authority vs page authority is that the domain authority provides an overall view of a website’s authority, considering the cumulative impact of all its pages. It reflects the collective strength of a domain in the eyes of search engines. 

On the other hand, page authority considers the authority of individual pages within a domain. While DA helps you calculate the overall credibility of your website, PA guides your SEO strategy to the page level. It helps you identify which keywords or topics to target for a specific page to make it rank well on search engines. 

This way, you can follow a granular approach to search engine optimization of your website and its pages. 

Let’s have a look at an example showing the difference between domain authority and page authority within a website.

Importance of Domain Authority and Page Authority

In the eyes of expert digital marketers, both domain authority vs page authority play an important role in determining a website’s success. A website with a high DA is perceived as an authority in its field. This authority extends across the entire domain, impacting the trustworthiness of all its pages. 

On the other hand, higher PA for specific pages reinforces your website’s expertise in particular topics, building trust among users seeking information in those areas. 

Moreover, users also trust websites with higher domain authority and page rank. This improves the credibility of that website and increases opportunities for more business your way. This ultimately increases your overall brand perception and trustworthiness in the eyes of search engines. 

So, even if domain authority vs page authority does not directly contribute to search engine rankings, they can have an indirect effect in increasing your online visibility and improving your rankings on search engine results pages. 


Importance of DA and PA in Link Building Strategies

Businesses looking to acquire backlinks opt for websites with higher domain and page authority. This page authority vs domain authority link building then increases the demand for your website in the digital marketing landscape. 


Tools for Measuring Domain Authority vs Page Authority

There are some popular tools for measuring domain authority and page authority in SEO. All of these tools have their own metrics and analysis algorithms to calculate the domain and page authority. Have a look at the top 3: 


  • Moz 

As mentioned above, Moz is a pioneer in providing DA and PA metrics. It offers a comprehensive suite of SEO tools, including the MozBar browser extension for quick insights and the Moz Link Explorer for in-depth analysis of backlink profiles and overall SEO analysis of a domain.

  • Ahrefs 

Ahrefs is also an SEO toolset that includes Site Explorer for domain analysis and individual page metrics. But Ahrefs has different metrics as compared to Moz. Domain Rating (DR) is a similar metric to DA, while URL Rating (UR) corresponds to PA.

  • SEMrush 

SEMrush is a digital marketing toolkit that offers insights into both domain and page authority. Its Site Audit tool provides a complete overview of a website’s SEO health. SEMrush’s authority score is different from both Moz and Ahrefs, which means it has its own metrics for calculating the domain and page authority scores.

In these screenshots from three different SEO tools, it can be easily seen that domain authority/rating/score is not a universal metric. This is the reason search engines don’t consider these metrics as search engine ranking factors. 


How to Increase Page and Domain Authority

There are different strategies used to increase the page and domain authority of your website. We have also discussed some of these strategies in the above paragraphs.  


Strategies for Increasing DA

To increase your website’s DA, you will need to invest in quality link-building for your website. Look for industry experts and relevant businesses in your niche and try to get backlinks from them. You can also avail Globex Outreach’s Link Building services to help you get quality and relevant backlinks from thought leaders in your industry. 

Another thing you can do is to publish content on your website and social media channels that is relevant and useful for your target audience. Moreover, investing your time and other resources in improving the technical SEO of your website also helps increase your site’s DA. 


Strategies for Increasing PA

While DA is more about getting backlinks and building the overall authority of your website, you will need to focus on internal linking best practices to improve the PA of your website. Also, ensure content optimization for specific keywords on each page of your website to make it visible to potential audiences on search engine result pages. 

User experience enhancements on your web pages can also be a good practice for improving the PA of your specific web pages. Last but not least, pay special attention to content. In this case, keep updating the old content on your website along with publishing the new one. This will improve the credibility of each page of your website and increase its PA. 


Common Misconceptions about Domain Authority and Page Authority


  • Higher Domain Authority Guarantees Top Rankings

While a high DA is generally a positive signal, it doesn’t guarantee top rankings for all pages. Individual page-level factors, relevance, and content quality also play crucial roles in rankings. 


  • Focusing Solely on DA Is Sufficient for Improved Rankings

While DA is an essential metric, focusing solely on it may overlook specific page-level optimizations. Ignoring page authority score can lead to missed opportunities for enhancing the visibility of key pages. So, you will have to work on page-level to improve the structure of your website and publish quality content to improve your website’s rankings on search engine results pages. 


  • DA and PA is Only Relevant for Link Building

DA and PA are relevant across various industries and business types. E-commerce sites, service providers, and informational websites can all benefit from understanding and optimizing DA and PA for websites and specific product or service pages. 


  • DA and PA are Fixed Metrics 

DA and PA are dynamic metrics that can change over time with the changes within a website. Regular monitoring, analysis, and optimization efforts are essential for maintaining and improving these scores, thereby getting the trust of consumers. 



So far, we have learned the definition and difference of domain authority vs page authority, factors affecting both of these, and some common misconceptions about both metrics. While not a direct ranking factor for search engines, domain and page authority is essential for effective SEO. So, it’s important that you understand how to use these metrics wisely to boost your SEO efforts.
