The Simple Definition
Created by Moz, Domain Authority (DA) is a search engine ranking score that predicts how likely a website is to rank on search engine result pages (SERPs). Scores range from 1 to 100, with higher scores indicating a greater ability to rank.
How DA is Calculated
DA is calculated by evaluating multiple factors, including linking root domains and total number of links, into a single score. This score can then be used when comparing websites or tracking the "ranking strength" of a website over time.
Common DA Myths
-
01
"Google Uses DA in Rankings"
False. Google has their own algorithms. DA is a third-party estimate of those algorithms.
-
02
"Higher DA Always Means Better Traffic"
False. A DA 20 site with better content can easily outrank a DA 50 site for specific keywords.
Why Should You Care?
If DA isn't used by Google, why do SEOs obsess over it? Simply because it is the most accurate proxy we have for a site's overall quality and trust in the eyes of search engines.
