💡 Did You Know?
Did you know that Domain Authority (DA) isn’t a Google ranking factor? That’s right—search engines like Google don’t use DA when crawling, indexing, or ranking websites.
Instead, Domain Authority is a proprietary metric developed by Moz, designed to help marketers and SEOs estimate how likely a website is to rank in search engine results.
While not used by Google, it remains a popular way to benchmark website strength, track growth, and evaluate backlink profiles.
In this article, we’ll explore the best free SEO tools to check Domain Authority, so you can quickly assess your site or competitors without spending a dime.
