Domain Authority [DA]

Domain Authority
« Back to Glossary Index

Domain Authority or DA is a search engine ranking score developed by Moz that estimates how likely a website is to rank in SERPs. It ranges from 1 to 100, with higher scores approximating a greater likelihood of ranking.

The domain authority can also be used to describe a given website’s relevance to a specific subject area or industry.

How Valuable is DA?

The DA of a site can be a helpful metric to know a website’s status in relation to its competitors, but it is essential to emphasise that it is not a ranking factor for Google. Because of this, please be aware that improving your DA score will not directly contribute to an improvement in your rankings.

It should only be used to indicate performance and how your website looks compared to others.

Many other tools have their own Authority Score metric, but the original was created by Moz. Each calculates this score differently; for example, Semrush’s Authority Score uses data from backlinks, referring domains, search traffic, etc.

Whichever you use, remember to keep it consistent for accurate comparison.
