What is Domain Authority?Domain Authority or DA is basically a search engine ranking score for websites, which is designed to predict how well a particular website or domain will rank on the search engine results page or SERP. To put it simply, this search engine ranking score is used to anticipate how high or low the position of a website might be, i.e., around what position a website might appear on the search engine results page. Domain Authority or DA is developed by the popular SEO tool site and SEO software company, Moz.
The Domain authority score of a website may range from 1 to 100. Moz evaluates numerous factors to calculate the Domain Authority or DA score. These factors include the linking root domains as well as the total number of links in a single domain score, among others. The ranking score of different websites can be used to compare those websites based on their respective ranking strengths or even keep track of how the ranking strength of a website changes over time.
The Domain Authority score of a website is not considered by Google and other search engines as a factor to determine how and in what position different web pages appear on the search engine results page or SERP. This means that the Domain Authority score of a website is not used to improve the SEO of that website. Rather, it is simply an indication of the performance of that website and its rank on the search engine results page.
Why is Domain Authority important?Even though the Domain Authority score of a website is not directly used by Google and other search engines to rank web pages and sites on the search engine results page, the DA score of a website is very important. This is because the Domain Authority score provides valuable insights on the overall performance and ranking of a website on the SERP. These insights can be very useful in simplifying the task of making appropriate changes to improve the performance of a website.
So, although the DA score does not directly impact SEO, its knowledge can be used to analyse and understand the things that can be done to improve the overall SEO of the site. In simple words, when the Domain Authority score of a website is known, an idea is obtained on how well the website is performing and ranking on the search engine results page and how this performance and rank has changed over time.
This information can be used to analyse what is causing the changes in the ranking of the website and then make the necessary modifications in the site and web pages to improve the SEO and performance. Apart from this, the Domain Authority score of a website can also be used to compare different websites based on their ranking strengths and conduct competitor research, which again can be very valuable for impacting the SEO of a website.
What is The Difference between PA and DA?There is only one major difference between Domain Authority or DA and Page Authority or PA. The terms, "Domain Authority" and "Page Authority" are very closely related to each other. In many ways, Domain Authority and Page Authority are very similar. While both Domain Authority and Page Authority are calculated using the same methodology and by evaluating the same factors, the only major difference between the two lies in the fact that the Domain Authority or DA score of a website indicates the ranking strength of the entire domain and its subdomains, whereas the Page Authority or PA score of a web page only predicts the ranking strength of a single page of the website.
Both the Domain Authority or DA of a website and the Page Authority or PA of a web page are very important for gaining insights on improving the performance and SEO ranking of the website. However, in some ways, Domain Authority holds more value than page authority. This is understandable because Domain Authority is concerned with the entire website unlike Page Authority, which is only concerned with one web page. Moreover, Domain Authority has a comparatively wider scope and greater potential than Page Authority in terms of effecting website visibility. Also, DA is bigger than PA and hence, it essentially helps to improve the performance and SEO ranking of a website for a much longer time than Page Authority.
How Does the 100 Point System Work?The value of the Domain Authority or DA score of a website can range from 1 to 100. This DA score has a direct relation with the ranking and performance of websites. This means that the higher the Domain Authority or DA score of a website, the greater is the chance of a high ranking or visibility of that website on the search engine results page. Whereas a website with a lower Domain authority score will likely have a lower ranking in the search engine results page, which is not good for the traffic or performance of that website. As the values of the DA score of websites are limited between 1 and 100, the lowest score for Domain Authority that a website can have is 1 whereas the highest possible DA score is 100.
Websites with the highest DA scores usually perform the best in terms of traffic. Websites that have a DA score of less than 40 usually don't rank very well. Such a DA score can be considered as below average. Average DA scores range between 40 to 50. A DA score ranging from 50 to 60 is considered to be above average or good while a DA score of more than 60 is considered to be excellent and the best ones are close to 100. Domain Authority uses a logarithmic scale, which means that it is easier to rise a below average DA score to an average DA score but much harder to rise a good DA score to an excellent DA score.
What is a Normal DA (Domain Authority)?The average range for Domain Authority is considered to be between 40 to 50 and a good score for Domain Authority is anything from 50 to 60. These two ranges make for a normal Domain Authority or DA. The reason for this is the fact that most of the websites have a Domain Authority score that falls in this range, i.e., a DA score which is either average or good. The DA score of a website is not always constant. It may go up or down depending on a number of factors. However, for most websites, the Domain Authority score range usually stays within the normal limit. It is very likely that a website with a normal Domain Authority or DA will rank higher than the ones with a Domain Authority score of below 40.
Compared to the websites with higher Domain Authority scores of more than 60, a website that has a normal DA score is likely to lag behind on the popularity scale, i.e., the performance of websites with normal Domain Authority will plausibly be lower compared to that of the top websites. As the Domain Authority follows a logarithmic scale, it becomes harder to increase the DA score as it progresses towards the higher end. However, it is not impossible to do so and many different measures can be taken to improve the DA score of a website from normal to excellent.
Where Should Your Focus Be - Page Authority or Domain Authority?The authoritative strength of the whole domain defines the domain authority whereas that of a single page on a particular domain is the page authority. Domain authority gives you flexibility as to when, where and how to create your content and related links. Its effects are wider but then, the time and efforts required to increase it are much more than the page authority.
Domain authority cannot be increased suddenly but there are tactics using which it can be improved over a period of time. But if you invest in it and give it enough time to improve, your inbound traffic will be more. This is so because here you are not focusing on just one page but many pages at a time. Domain authority works well in the long term and helps in building the brand. But the pages that will stand out from others will automatically attract many more links and also the authority. Also, working on a single page won’t make you suffer in the short term or long term.
Although both are important but still domain authority seems to have an upper hand and should be given more attention than page authority. The first reason is that it is a long term investment. It removes the issue of keeping all your eggs in a single basket (talking in terms of authority). Page authority should not be ignored either. If you want to emphasize on a particular page or maybe the content that you think is exclusive then you can push it with page authority. The point is to pay attention to domain authority for building your brand, and on page authority if you have a page to compete for a specific keyword.
