Definition

SEMrush domain authority score is a compound metric used for measuring a domain or webpage’s overall quality and SEO performance. The score is based on several different metrics which represent trustworthiness and authority. It utilizes a neural network and machine learning to ensure the score is always accurate and fresh. Authority scores indicate a domain’s SEO quality and a higher number means a stronger domain. But keep in mind, Authority Score can measure a domain and page, but cannot measure a subfolder or subdomain’s authority at this time. If you are researching a subfolder or subdomain, this module will show the authority score of the root domain. All authority scores calculated are relative to the scores of the domains within the same range of authority score. Simply put, this means any improvements by close competitors can lower your score even if nothing on your site changes.

Domainers use the SEMrush Domain Authority score to determine if an expired domain currently has traffic or backlinks, and whether it might be spam or not. Generally speaking, the higher the Authority Score of a domain, the more trusted it is. It’s based on a scale ranging from 1 to 100, so the closer the Authority Score is too 100, the better.

How Is It Calculated

The SEMrush Domain Authority Score is a result of calculations run by a neural network algorithm which uses machine learning to measure every domains authority based on quality, popularity, and backlink signals. The calculation is carried out in two steps:

1) Their initial machine learning algorithm uses organic search data, website traffic data, and backlink data to understand the rankings of the most popular and trusted domain names on the web.
2) The second algorithm uses backlink data to detect how a website increases or decreases its authority by gaining links. The metrics in this calculation include: the number of referring domains, the authority of each referring domain, follow vs. nofollow links pointing to the domain, follow vs nofollow links pointing away from the domain, the total number of backlinks, the total number of referring IP addresses, and more.

The domain score value is measured on a scale from 0 to 100, with 100 being the strongest. The final score is measured in relation to the most authoritative domains. Keep in mind, there are only a few domains on the Internet with the scores above 95.

Usage

The purpose of an SEMrush Domain Authority Score is to serve as an indicator of the overall quality of a specific domain or website. For domain investors, this can give them more insight about an expired domain and how it was used in the past. A good Domain Authority Score (one that is similar to websites within the same or neighboring niches) will mean the domain likely good-quality and has existing traffic and backlinks. Ideally, you want to have the highest Domain Authority score out of your competitors, but you don’t want it to be so high that you’re out of competition with them. If all of your direct competitors have scored between 40 and 50, a good domain authority score for your website should fall between 55 and 60.

Businesses can also use the SEMrush authority score for domain comparison. When doing so, they should judge a domain names Authority Score in relation to similar websites in the same or neighboring niches. The more comparable a particular domains score is with others similar to it, the better. Remember, when looking at the authority score of an expired domain you shouldn’t only be looking for domains with the highest scores, but instead looking for domains with scores that are similar to others in its niche.

It’s extremely common to use SEMrush as a filter for SEO or traffic domains. If a domain was previously developed and has existing traffic coming into it which isn’t from type-ins, it is expected to have a domain authority score, even if it’s only in the 10-20 range. Domains which are not developed and receive mostly just type-in traffic (such as dictionary word domains that are not developed) will likely not be scored unless they have links pointing into them from around the web.

Availability

SEMrush Domain Authority can be seen by looking up your desired URL inside the Domain Overview toolkit after logging into semrush.com. The company has a Free Authority Score Checker tool available here. Anyone creating a brand new SEMrush account will also receive 10 free requests. After that, you will need to pay either monthly or annually for continued access.

SEMrush data is also available to Business Accounts via an API.

One simple web request can check the SEMrush domain overview which includes several different metrics: Domain Authority, Referring Domains, Backlinks, Keywords, and more (needs your own, working SEMrush API key from SEMrush). Keep in mind, you will need an SEMRush Business Account and will also need to purchase an API package. Here is an example web request:
https://api.semrush.com/?key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&type=domain_ranks&export_columns=Db,Dn,Rk,Or,Ot,Oc,Ad,At,Ac,Sh,Sv&domain=expireddomains.com.com&database=us

The SEMrush API allows customers to quickly analyze only what is relevant to their website, instead of spending hours of time parsing through tons of data. The API has also been designed to be easily integrated into any kind of application, widget, or dashboard. It also fits nicely with solutions built on e-commerce platforms or CMS like Magento, Shopify, Drupal, PrestaShop, and many others.

SEMrush distinguishes between three different types of requests made via the API: lines, calls, and keywords. The cost of requests is measured in units. Units are determined by the type of report or request. Delivering historical data requires more units than live data. One dollar is equal to approximately 20,000 API units and performing one SEMrush domain request is 10 API units per line.

It’s recommended that you calculate your API request limit before purchasing any API package. You can increase your request limit by upgrading your subscription or by purchasing API units at anytime.

Reliability

The wide variety of tools that SEMrush offers makes them a top choice for both businesses and individuals because they can perform so many different tasks in just one place. Domain Authority scores are determined using a neural network and machine learning which makes it almost impossible to manipulate. It can’t be faked with bots and no toolbars are used to gather data. If you try to cheat the system with spammy backlinks the SEMrush algorithm will notice it and your score will drop. Good backlinks and search engine traffic can’t be faked, so if a domain owns a high Domain Authority score than it’s likely a good-quality domain and not spam.
