You’ve heard the term before and you know it’s important, but you’re not exactly sure what it is — let alone how to use it to boost your business.
Never fear! By the end of this article you’ll know the exact definition of domain authority, how to increase your website’s domain authority score, and more. That’s right, we’re about to shine a light into the darkness and help you understand this important marketing concept.
Sound like a plan? Then let’s get to it…
What is domain authority?
Since Moz created the domain authority metric, we’ll refer to them for a definition:
Domain authority, or “DA,” is “A search engine ranking score that predicts how likely a website is to rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank.”
Moz goes on to say that, “Domain Authority is calculated by evaluating multiple factors, including linking root domains and the number of total links, into a single domain authority score.”
It’s important to note that domain authority predicts success, it doesn’t necessarily represent success. The metric is not used by Google and boosting your DA won’t automatically make your website rank higher in Google search results.
In a nutshell, your website’s domain authority score will help you determine your competitiveness in your niche. This, in turn, will help you choose keywords strategically.
For example, let’s pretend your website’s DA score is 56. If you’re competing for a specific keyword against sites with domain authorities between 39 and 47, you’ll know that a well-written blog post or web page has a good chance of ranking. But, if you’re competing against sites with domain authorities in the 80s, you’ll probably want to target a different keyword.
Other measures of page authority
Until about 2019, Moz’s domain authority metric was the gold standard when assessing websites’ reputations. Moz allowed anyone to perform unlimited free domain authority-checks anonymously. Through a little page on their website, users could type in a website’s URL and get domain and page authority results immediately.
As it happens, Moz made the decision to remove this feature from the public, requiring users to create accounts and provide an email address before using the tool. As a result, bots and automated systems that were using Moz’s DA metrics were unable to continuously ping the form, so other companies stepped up to the plate and devised their own domain reputation ranking tools.
These other tools don’t use the expression “domain authority” and are named close variants like “domain reputation” or “site authority,” but mean to ascertain the same phenomenon—a site’s specific reputation score.
It’s important to note that most of these systems do not play nicely with one another. A Moz DA of 51 might be equivalent to a 76 in another tool. Whichever metric of page health you use, be sure to keep it consistent.
Domain authority versus page authority
Before we dig deeper into domain authority, we need to clarify: domain authority and page authority, another metric developed by Moz, are different. In the company’s own words:
“Whereas Page Authority measures the predictive ranking strength of a single page, Domain Authority measures the strength of entire domains or subdomains.”
