What is Domain Authority?

Domain authority is a metric generated by Moz (an external company unrelated to any search engine) that predicts how well a website will rank in search engines like Google. Each website is given a score from 1 to 100, with 0 being a brand new site and 100 indicating that a site is highly able to rank on search engines.

Your website’s domain authority (DA) tells you the overall authority of your entire domain. A website’s page authority (PA) is the authority of an individual page on your website.

Why is domain authority important?

As a webmaster, the domain authority metric gives you a better idea of how well your website is performing on search engines. Your website’s DA will indicate to you if your SEO efforts are working.

Also, it gives you an ego boost when you see your domain authority score increase after an update. It also gives you bragging rights (if you’re into that) because many bloggers use DA scores to gauge a website’s authority online.

It also allows you to have a better understanding of whether a particular website is ranking well on search engines or not. This will come in handy when:

  • You are choosing which website to guest post at
  • Deciding if a competitor is a “larger” or “smaller” organic competitor – it can be hard to determine a website’s clout just by looking at the website. DA is a good website metric to check.
  • To see where you stand in relation to your competitors

However, do note that the domain authority (DA) metric is not perfect. It does not indicate your website’s actual standing in Google’s eyes but only an estimate of it. Google does not take your DA score into account when ranking your articles.

How do you check your website’s domain authority?

You can check a website’s DA by using MozBar (a free Chrome-extension), Link Explorer (a backlink analysis tool), the SERP Analysis section of Keyword Explorer, and almost every other SEO tool on the internet.

Which domain authority checker tool should you use?

I highly recommend using the Mozbar to check your website’s domain authority if you are using Google Chrome.

It is free and easy to use. I personally use the Mozbar for all my domain authority needs.

If you don’t want to use Google Chrome as your browser, you can check your website’s domain authority by using the Link Explorer – all you have to do is type in your URL and it will crank out what your website’s DA is.


How do you install the Mozbar?

You can install the Mozbar like you install any other Chrome extension. Click on this link and then click on the “Download Mozbar Free” button:


You will then be asked to download the Mozbar from the Chrome Webstore.

Once you have downloaded the MozBar, you would be able to see each website’s DA. You may have to log in with a Moz account (free!) before you can see your website’s domain authority.

As you can see from this screenshot, my domain authority is currently 39.


You may need to double click on the extension icon if you can’t see a number:


What is a good domain authority score?

It depends on your competitor’s score. As domain authority is a comparative metric, there isn’t a definite “good” or “bad” score.

If I really had to give a ballpark number, I would say that the average website’s domain authority is probably at about 20 to 30.

Do note that it is much easier to go from 0 to 10 as compared to trying to get from 40 to 50, and so on.

How is your domain authority score computed?

Moz claims to use an aggregate of metrics and link data that have an impact on the authority score. It would be difficult to determine exactly how Moz calculates the DA because they use a complex algorithm.

The list of metrics that Moz takes into account include:

  • MozRank (Quantity of links)
  • MozTrust (Quality of links)
  • Spam Score
  • … and many more, Moz doesn’t really specify the exact list so we can only guess.

However, it is a well-known fact that the number of high-quality incoming links you have is the single most important determining factor that Moz takes into account when calculating your DA score.

When is the next Moz domain authority update?

Moz will typically update domain authority scores once a month. You can check this page to see when their next update will be.

How do you improve your domain authority score?

There are many different ways to increase your domain authority score, much like how there are many different things you have to do if you want to DIY your own SEO.
