With over a billion websites trying to make their mark on the internet, it’s important for them to be ranked based on authority and trust. These range from well-established media publications to spam bots attempting to compromise countless internet users. When a user searches the web for a specific keyword, Google and many other search engines use algorithms to decide which results to display, based on a variety of factors that are not fully transparent to the average internet user.

The authority of a website can be determined using several SEO tools, with scores ranging from 0 to 100—0 representing a newly created website and 100 being a value that even Facebook or Google seem unable to reach. In this article, we will explain the process of checking a website’s authority and which values should be considered in a Link Building campaign.

As mentioned earlier, there are multiple SEO tools to determine a website’s authority because Google does not make its authority algorithm public. As a result, different organizations have developed their own algorithms to understand why one site is considered better than another. For example, MOZ has DA (Domain Authority), Ahrefs has DR (Domain Rating), and Semrush has AS (Authority Score).

This article is not about deciding which scoring system is the best. The truth is that each system has its pros and cons, but if you avoid comparing apples to oranges (like DR vs AS or AS vs DA), you can differentiate between them. From an SEO perspective, a site with 50 DA has more authority than one with 30 DA. MOZ’s DA is the most popular measurement system because it calculates scores based on the backlinks a site has, as well as traffic estimates and other variables such as content, on-page optimization, and more.

Marketing PixelFlowAgency uses moz.com. The menu includes a section for free SEO tools called Free SEO Tools, where you can analyze your domain for free. As shown in the figure below, this analysis provides information on DA, the number of links to the site’s root, and spam score. It’s important to note that this method of determining a site’s authority is only an SEO foundation and should not be considered the sole element in a Link Building strategy.

The value of a website should be determined based on multiple factors, including DA, content quality, spam score, and the niche the site operates in. For example, a site that publishes cooking recipes will have higher authority in the culinary space than a technology site. In conclusion, a website’s authority can be measured using various free online tools, but its value for link building or partnerships should be assessed by an SEO expert.
