Moz Domain Authority: How Is It Calculated?

What is Moz Domain Authority?

The Domain Authority (DA) score was created by Moz to predict how likely a website would rank in search engine results pages (SERPs). The Domain Authority score varies from one to one hundred, with a higher number indicating that a website is more likely to rank on SERPs, particularly in terms of your niche’s competition. This score can be used to compare websites overall Off Page SEO power and track the strength of their rankings over time.

How is Moz Domain Authority Calculated?

The Moz Domain Authority, according to Moz itself, is calculated using dozens of parameters and is based on data from their Link Explorer web index. Like most search engine optimization tools and metrics nowadays, the Domain Authority calculation employs a machine learning model to identify the best algorithm that links Moz’s link data with rankings on massive real-world search results, that they use as benchmarks. It does not take into account a website’s anchor text.

Domain Authority score is specifically evaluated using linking roots domain and a total number of links into a single score. The calculation can change over time because of algorithm updates. Last 2019, the Domain Authority 2.0 update is released, wherein the calculations come from the machine learning algorithm’s predictions on how often Google uses a domain in search results.

Since it is calculated using machine learning, a website’s score can fluctuate from time to time, as more, fewer, or different data points become available and are added to calculations. More established and authoritative domains will have increasingly larger link profiles, taking up more of the high DA slots. Therefore, it is easier to increase scores from lower scores than increasing scores closer to one hundred.

Domain Authority vs. Page Authority

Page Authority evaluates the strength of a single page’s predictive rating, while Domain Authority assesses the strength of the entire domains or subdomains. The measurements are still calculated by the same methods, so they are somewhat similar.

Sites with a very large number of high-quality links are at the top end of the Domain Authority scale, while small websites with fewer inbound links will have much lower DA scores.

  1. Suspicious link building. Unethical methods relating to increasing connections through link building such as engaging in link exchange for the sole purpose of cross-linking, using bots to generate links automatically, or purchasing or selling links that pass Google’s PageRank.
  2. Keyword stuffing, which practically aims to manipulate page ranking by stuffing ranking keywords onto pages.
  3. Slow page speed. Google, as most people do, isn’t fond of sluggish websites.
  4. Unmaintained technical SEO. Search engines are always evolving. Google, for example, provides new updates on a regular basis to improve its usefulness. It’s critical to stay current with search engine upgrades in order to avoid being penalized.
  5. Toxic backlinks. Spammy sites will link to your site on a regular basis in the hopes of improving their own ranks. Your DA may suffer as a result of this. When Google penalizes a website, it examines the sites to which it is linked.
  6. Unoptimized content. Not only meta tags and URLs should be optimized, but old content as well. Because the initial information may have changed, informational content must be reoptimized and modified.
