10 Best Domain Authority Tools to Check in 2025 (Free & Paid)

How does your website stack up against competitors? The secret of SEO practitioners is understanding domain authority (DA) and comparing it to search engine results page (SERP) top results. But how do you measure it effectively? With the right domain authority tools.

These will be essential companions for evaluating your website’s influence and strength in search results. 💪

DA isn’t just a vanity metric, and knowing it thoroughly will definitely help you improve your site’s visibility, content strategy, and overall SEO performance. You’ll find many DA checkers out there, but using the right one can make all the difference.

That’s why we’ve compiled this comprehensive guide featuring the 9 best domain authority tools for 2025, both free and paid. From their standout features to pricing and limitations, we’ll help you navigate the options!

What is Domain Authority (DA)?

Domain Authority is a metric developed by Moz to estimate a website’s ranking potential in SERPs. Scored on a scale of 0 to 100, a higher DA indicates a stronger likelihood that a site’s pages will rank well.

This is not a ranking factor, which means Google does not use this metric. DA serves as a comparative tool for evaluating the competitiveness of a domain within its industry. 🤺

Search Atlas features Domain Power, a proprietary metric that’s more accurate than Domain Authority.

It’s calculated using various factors, with the most significant being the quality and quantity of inbound links pointing to the domain.

Importantly, DA isn’t about striving for a perfect score of 100, but rather about understanding what you need to improve on your website. For example, if your DA is lower than your competitors’, that might mean their website has a stronger backlink profile.

What is Page Authority?

Page Authority (PA) is a metric that predicts a single page’s likelihood of ranking in search results, also scored from 0 to 100. While PA measures the predictive ranking strength of a single page, DA measures the strength of entire domains or subdomains.

What Should Domain Authority Tools Do?

While there are many free domain authority tools available, you can’t afford to waste time testing unreliable ones or making SEO mistakes by basing decisions on flawed data. So, what should the ideal tool offer? 🤔

First, you need bulk analysis capabilities. If you’re competing in a crowded market, analyzing multiple websites simultaneously saves time and provides valuable insights into industry trends.

Second, it should provide both DA and PA metrics. This combination allows for a comprehensive view of overall domain strength and the ranking potential of specific pages.

Third, the best tools go beyond basic metrics. Look for those that double as complete SEO solutions, offering features like backlink analysis, PR outreach capabilities, press release distribution, and even automated link building strategy.
