The measurements are still calculated by the same methods, so they are somewhat similar. Page Authority evaluates the strength of a single page’s predictive rating, while Domain Authority assesses the strength of the entire domains or subdomains. Therefore, it is easier to increase scores from lower scores than increasing scores closer to one hundred. More established and authoritative domains will have increasingly larger link profiles, taking up more of the high DA slots. 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. 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. The calculation can change over time because of algorithm updates. It does not take into account a website’s anchor text.ĭomain Authority score is specifically evaluated using linking roots domain and a total number of links into a single score. 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.

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. This score can be used to compare websites overall Off Page SEO power and track the strength of their rankings over time.

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.

The Domain Authority (DA) score was created by Moz to predict how likely a website would rank in search engine results pages (SERPs).
