What Is Domain Authority (DA)?

Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine result pages (SERPs). It ranges from 1 to 100, with higher scores corresponding to a greater ability to rank.

How Is Domain Authority Calculated?

DA is calculated using dozens of factors, but key ones include the number of linking root domains and the total number of backlinks. It uses a machine learning model to predict how often Google uses a domain in its search results.

What’s Considered a Good Domain Authority?

Generally, a DA score of 50 and above is considered good, while 60+ is excellent. However, what's "good" depends on your niche. For local businesses, even a DA of 20–30 could be competitive.
