Domain Authority Definition & Meaning

What Is Domain Authority?

Domain Authority is a search engine ranking score that estimates how well a website will rank in the search engine results pages. Domain Authority was developed by Moz and scores range from 1 to 100, with higher scores indicating a better possibility of ranking.

Domain Authority (or DA) is important for search engine optimization (SEO) analysis because it closely represents the ranking capability of a website ranking in Google. DA is a widely accepted scoring metric for SEO experts and link builders to measure a website’s performance in the search engine results pages (SERPs). That’s because a website with a high DA score typically ranks better than a site with a low DA metric.

However, it’s important to keep in mind that Domain Authority is not a metric that Google uses in its ranking algorithms. Google has its own proprietary PageRank and TrustRank algorithms that determine the popularity and trust of a domain using more than 200 factors. But, if you take a closer look at the highest-ranking websites in the SERPs, you’ll often see that they have a good Domain Authority score.

Therefore, you should work to increase your website’s Domain Authority score because it can indirectly help the overall search engine visibility of your website. A good Domain Authority is between 50 to 60 on the DA scale to compete in the SERPs for moderately competitive keywords.
