What is Domain Authority

// // 12 comments
Domain Authority
Domain authority (DA) is a score calculated logarithmically and given to your domain (most authoritatively by Moz.) calculated on the basis of the unique root domain linking back directly to your site.

It is also determined to calculate how a site will perform in search engine but it is not definitive as links are one of the factors by which search engines determine ranking of a website.

This does not mean that a site with better domain authority will always rank number one or we would see all pages of Wikipedia (with DA 100) at the top of SERP.

Domain Authority Measurement

Moz score Domain Authority on a 100-point, logarithmic scale. Thus, it's easier to grow DA score from 20 to 30 than it would be to grow from 70 to 80.
Domain Authority metrics are incorporated into dozens of SEO and online marketing platforms across the web.
You can measure Domain Authority using Open Site Explorer or the MozBar, Moz's free SEO toolbar. Moz incorporates Authority metrics into all Moz Analytics campaigns, as well as the Mozscape API.




Domain Authority Calculation Parameters

There are many major and minor factors behind Domain authority calculation. It is based on the data from Mozscape Web index, number of links from various sources, amount of content present in search results and several other factors.Let’s take a deeper look at the factors involved-


  • Age and popularity of the Domain :Simply put, the more is the age of the domain name the more reliable it is for getting information online. Up-time and regular updates too play a crucial part in it. Because of the humongous amount of domain names being launched every day, age becomes a crucial  factor.
Domain popularity too matters a lot. To be precise, it’s just the comparison of total outbound links to inbound links to your website. Obviously more number of inbound links means that your site is popular.
  • SERPS visibility : The more content you have in top search results the more likely you will gain authority. And future posts have a better chances to rank well.
  • Value back links : Back links can be made with an obvious strategy of commenting on do-follow blogs. But personally I never recommend it to my readers, my focus is always giving them the best, and so content gets naturally shared on high PR forums and blogs. That’s the best way to get back links. Let your work speak for you.
  • Amount of content : More the content published by you which has been indexed, more is the chances of having a higher authority. Writing more quality content will give you a better DA.

Domain Authority and SEO

Unlike other SEO metrics, Domain Authority is difficult to influence directly. It is made up of an aggregate of metrics (MozRank, MozTrust, link profile, and more) that each have an impact on this score. This was done intentionally; this metric is meant to approximate how competitive a given site is in Google.com. Since Google takes a lot of factors into account, a metric that tries to calculate it must incorporate a lot of factors, as well.


The best way to influence this metric is to improve your overall SEO. In particular, you should focus on your link profile—which influences MozRank and MozTrust—by getting more links from other well-linked-to pages.
