Domain Authority (DA) is a measurement from Moz of how powerful a domain name is in terms of link popularity. It ranges from 1-100, with most websites falling into the 30-50 range.
Some website owners and SEOs obsess over their Domain Authority score as if it’s an end-all-be-all ranking factor, but don’t fret if your site has a lower DA – there are plenty of things you can do to increase it.

Why are these tools needed?
Some small businesses might not need high DA scores because they focus on other marketing channels or niches that aren’t as competitive. That said, here are five free tools you can use to check your Domain Authority:
- Google PageRank Chrome Extension
- SEOMoz Open Site Explorer
- Ahrefs Toolbar (Chrome and Firefox)
- Contconcord Domain Authority Checker
Moz’s free toolbar extension for Chrome and Firefox, Mozbar, provides Domain Authority scores for any site you visit. You can also see other important SEO metrics such as Page Authority, link equity, mozRank, and more.
2. Google PageRank Chrome Extension
This simple chrome extension displays the Google PageRank of any page you’re visiting – a good indicator of how powerful that page is in terms of links (although it’s not always accurate). Install it here.
3. SEOMoz Open Site Explorer
SEOMoz’s Open Site Explorer is one of the most popular domain authority checkers available online today. It gives detailed information about a website’s backlinks, social shares, and more. You have to create an account to use it, but there are plenty of helpful resources on their blog if you’re new to SEO.
The Ahrefs toolbar includes domain authority checkers: “Domain Rating” and “URL Rating.” The former tells you how strong your entire website is compared to others, while the latter measures the power or strength of a specific URL against all.
Last but not least is the Contconcord DA PA Checker, which lets you check multiple domains simultaneously without going into the effort of checking them separately.
