Domain authority (DA) is a search engine ranking score that relates to the authority and strength of a website compared to other websites. As a site owner, it’s a good idea to use a domain authority checker tool to monitor your DA and see if your efforts are paying off.
Various factors are used to calculate a site’s DA score, such as the quality of backlinks, internal links, the website’s age, content quality and usefulness, and overall performance and SEO structure.
If your DA and Google ranking start to dip or rarely improve, this could indicate that one or all of the above is not working.
Take a look below at the best website authority checkers so you can keep an eye on your domain growth over time.

I love it and use it myself. I also have the Moz SEO Chrome Extension installed, which allows me to instantly view the domain authority of any site I visit.
The main features of the free Moz toolbar offers include:

- Page analysis. Here, you can study on-page elements such as the URL, page title, and meta description.

Ahrefs offers its own website authority checker, but instead of using the term ”Domain Authority” they call it ”Domain Rating”.
This score also runs on a scale from zero to one hundred, with a higher number indicating more authority a site has.
To work out a domain rating (DR), Ahrefs looks at:
- How many unique links a site has
- The ”authority” of those linking domains
- How many unique domains those sites link to
- Competition level of the site topic
- General website quality and on-page SEO.
You can also check a website’s backlink profile, any referring domains, and top pages and perform a competitor analysis to see potential areas for improvement.
