How to Check the Authority of Any Domain Name (3 Best Tools)

How to Check Domain Authority for Any Website

Do you want to easily check the authority of any domain name?

You can check domain authority before you buy a domain to predict how well your website will rank in search results. You can also use domain authority checkers to find out how competitor domains perform.

In this guide, we’ll show you the best tools to use to check the domain authority of any website.

But first, let’s be clear about what domain authority is and what we can understand from it.

What is Domain Authority

Domain authority (DA) is a score from 1 to 100 given to a domain to indicate its SEO strength. The higher the score, the better your chances of ranking on search engine results pages (SERPs).

So in other words, it serves as a scale to know whether the website has a likelihood of ranking for certain keywords.

Domain authority was created by a company called Moz – a marketing analytics software for SEO, links, and branding. Since then, a number of other SEO and analytics platforms have created their own version of domain authority.

In general, DA scores are calculated based on a number of factors including:

  • Total number of links
  • Linking root domain
  • Relevance of backlinks
  • Content quality
  • Social signals

An important thing to note is domain authority does not have an effect on Google rankings. It works independently of Google and only predicts how well a domain might rank on Google search results.

That said, DA scores can be really helpful to website owners, domain buyers, SEO specialists, and marketing professionals. It can help you estimate the domain’s ability to get organic traffic from Google.

Now let’s take a look at the top 3 tools to check domain authority of any website.

3 Best Tools to Check Domain Authority

1. Ahrefs


Ahrefs has their own website authority metrics to find out a domain’s SEO strength.

We’ll be looking at 3 of these metrics:

  1. Domain Rating (DR)
  2. Ahrefs Rank (AR)
  3. URL Rating (UR)

Domain Rating

Similar to Moz’s Domain Authority, Domain Rating is a website authority score that runs on a scale from zero to a hundred. The higher the DR, the better the domain’s authority.

Domain rating in Ahrefs

Ahrefs calculates DR based on the quantity and quality of external backlinks to a specific domain. It checks how many unique links are coming into the target website and it also checks the authority of those linking domains.

After that, it checks how many unique domains each of those sites link to. Finally, it uses an algorithm to plot out the domain rating score.

So DR is dependent on not only the total number of high-DR sites that link to your domain, but also on how many other websites these high-DR sites link to.

Keep in mind, it doesn’t account for any other variables like link spam, traffic, domain age, etc.

Now Ahrefs makes it clear that there isn’t a specific score that you need to aim for, such as 70 or 80. Domain ratings are relative and should be viewed in comparison to similar sites.

If your DR is higher than competitor/similar websites, then you have a better chance of ranking on Google. If they’re doing better than your domain, then you can use Ahrefs Site Explorer to analyze their backlink profile and find untapped link opportunities.

Ahrefs Rank

AR (Ahrefs Rank) is a more granular version of DR and ranks all the websites in the Ahrefs database by the size and quality of their backlink profiles.

This comes in handy when you find that your DR is the same as other websites. You can go a step further and check Ahrefs Rank (AR).

So if your domain AR is 1990, it means you stand at the 1990th position in their database according to your backlink profile. Then you can compare that to similar websites and see if they at higher or lower positions than you.

URL Rating

URL Rating or UR shows the strength of a page’s link profile. Instead of analyzing a domain, it checks just that specific URL making it a page-level metric.

So for instance, if you check the UR for a website, you’ll get the metrics only for homepage.

This rating takes into account both internal and external links. It also respects the nofollow attribute.

To make sure there are no linking loops – where two websites are exchanging rating scores in a loop – Ahrefs has a spotter to find and cut off these loops. It also checks for links that can artificially increase UR.

2. Semrush


Semrush is a marketing platform that can help you boost your SEO, content marketing, and social media marketing.

The Semrush Authority Score is a metric that measures a domain’s overall SEO performance and quality. You can use this tool to check the score for domains and individual web pages.

Semrush Domain Authority

The authority score is based on a number of factors including

  • Number of referring domains pointing to the site
  • Authority of each referring domain
  • Total number of backlinks pointing to the site
  • Follow vs. nofollow links pointing away from the site (outbound links)
  • Number of outbound links from each referring domain
  • Follow vs. nofollow links pointing to the site (inbound links)
  • Number of referring IPs pointing to the site
  • Number of referring subnets pointing to the site

The score is then measured on a scale of zero to 100. The higher the score, the better your domain authority. Similar to Ahrefs, you need to read this score in comparison to similar domains to understand whether your domain is performing better or worse than others.

Similar to Ahrefs, Semrush also has a domain ranker.

You can check the Semrush rank tracker to see where your domain is placed in their database.

3. Moz


Moz, the original maker of domain authority, developed the ranking score to predict how likely a website is to rank in SERPs.

This tool is free and can be used by anyone without signing up.

On the results page, you can view the domain authority, linking root domains, ranking keywords, and spam score. You can also see the top pages by links and the top linking domains.

Moz domain authority page

Moz’s Domain Authority tool is based on machine learning models and a predictive ‘best fit’ algorithm that correlates all the data it has across thousands (maybe even millions) of search results.

They use dozens of factors to calculate these scores including the total number of links and linking root domain.

Keep in mind that the domain authority score can fluctuate often and change over time. It can be affected by other domains gaining quality backlinks faster than you.

You can install the MozBar which is a free SEO toolbar extension for browsers.


Then when you visit a website, you can automatically see its domain authority, linking root domains, ranking keywords, and spam score.

Moz also has a Page Authority score that measures the SEO strength of individual pages.

That’s it! These are the top 3 tools to check domain authority. Next we’ll answer important questions about domain authority.
