How is the Domain Authority Calculated?

Domain Authority (DA) is a metric developed by the SEO consulting as well as research company Moz which measures a website’s likelihood to rank on search engines.

Domain Authority is useful for a predictive measure for PageRank, Google’s proprietary algorithm that plays a major role in determining search engine results. Due to the shroud of secrecy around PageRank, Moz’s DA metric is extensively considered to be one of the best third-party tools for evaluating domain strength.

DA or Domain Authority is a search engine ranking score prepared by Moz that predicts how well a website will rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a superior ability to rank.

Domain Authority is measured by evaluating several aspects, including linking root domains and a number of total links, into a single DA score. This score can then be utilized while comparing websites or tracking the “ranking strength” of a website over time.
You can view a website’s DA by utilizing MozBar (a free Chrome-extension), Link Explorer (a backlink analysis tool), and the SERP Analysis section of Keyword Explorer as well as dozens of other SEO tools across the web.

Domain authority is a metric which was developed by Moz (SaaS company), for the purpose of rating a website on a scale of 1-100. So the superior the domain authority of a website, the higher it’s ranking in search engines.

Instead of thinking of domain authority as calculate of your SEO effort, think of it as a competitive metric against other sites.  So if you compare your website’s DA score with that of your competitor’s site, the site with the higher DA score is likely to get top page rank in Google.

DA consists of 40 ranking signals such as the number of links pointing to the site as well as the number of linking root domains – fundamentally the number of other sites linking to your site.

The technical definition of Domain Authority

Domain Authority is based on data from our Link Explorer web index as well as uses dozens of factors in its calculations. The actual Domain Authority calculation itself uses a machine learning model to predictively find a “best fit” algorithm that most directly our link data with rankings across thousands of real search results that we use as standards to scale against.

Since Authority depends on machine learning calculations, your site’s score will often fluctuate as more, less, or different data points are used in the calculation.

How domain authority is calculated?

DA measures the authority of the whole domain.  Similarly, page authority (PA) is the computer of an individual page.

Domain Authority assigns a website as a whole a numerical value on a 1-100 (100 being the best and 1 being the worst) logarithmic scale. That means it’s far trickier for a site to move from 20 to 30 than from 80 to 90. Thus, the highest-ranked websites score considered far more authoritative than lower-ranked ones. DA is developed by combining more than 40 individual signals which are tracked as well as measured by Moz, many of which are Moz’s own inventions.

MozRank: This measures the collective popularity of a web page by counting both the number as well as the quality of websites linking to it.

MozTrust: This focuses on the reliability of websites linking to a page being graded. Being linked to by highly responsible websites, such as universities, large businesses or specialist government pages, results in a higher MozTrust rank.

Link Profile: Link profiling looks at both internal as well as external links to and from a website. A page which links to highly reputable sources as well as is linked to by reputable sources will have a good link profile. The significance of anchor text to the link is an extra major factor here.

As with Google search results, a webpage’s Domain Authority will vary on a daily basis. Those relying on DA in their metrics usually track it consistently as well as take drops in DA as a sign that they require to fix a problem in their SEO.

Domain Authority is not an absolute determination of your website’s search engine standing. Like all other third-party tools, utilize it as a directional tool to monitor overall SEO progress. Keep a close eye on traffic as well as rankings; when those improve, Domain Authority should generally follow suit.

The finest way to impact your website’s domain authority is to set up the best SEO practices. SEO Link building services, on-page optimizations as well as social media marketing will slowly help a domain build authority.

When looking at opportunities to enhance domain authority, consider:

Internal linking: Enhance site navigation as well as make sure content is linked from relevant pages.

Anchor text relevance: If anchor text doesn’t regularly include target keywords, focus on link building initiatives to increase anchors for significant terms.

Partners: Look into opportunities to make links as well as social shares from any partners you work with.

What is a “good” Domain Authority?

Normally speaking, sites with a very large number of high-quality external links (such as Wikipedia or are at the top end of the Domain Authority scale, whereas small businesses and websites with fewer inbound links may have a much lower DA score. Brand-new websites will always begin with a Domain Authority score of one.

Because Domain Authority is meant to be a predictor of a site’s ranking ability, having a very high DA score shouldn’t be your only objective. Look at the DA scores for the sites you’re straight competing within the SERPs and aim to have a higher score than your competitors. It’s best utilized as a comparative metric (rather than an absolute, concrete score) while performing research in the search results and determining which sites might have more powerful/vital link profiles than others. Because it’s a comparative tool, there isn’t essentially a “good” or “bad” Domain Authority score.

Whereas Domain Authority measures the predictive ranking strength of entire domains or subdomains, Page Authority processes the strength of individual pages.
