About Domain Authority Checker

Search Engine Optimzation is the practice of getting a website to align with Google’s search engine ranking factors. It is the process of optimizing your website to rank as high as possible in organic search engine results. When talking about organic search results, we refer to free search engine results when users search for anything using a keyword. This is different from pay-per-click or PPC advertising, which is a paid strategy that focuses on paid search engine placements.

Organic rankings on Google are determined by an algorithm that takes into account various page rank metrics. Google does not disclose it's algorithm and ranking factors, but we do know many of them based on what Google has revealed to us and what many SEO companies have found through experimentation and study of the search engine results. We also know that while ranking factors and algorithm do change from time to time, Google takes into consideration things like quality content, trustworthiness, website performance and user experience.

Many companies and brands try to use different metrics to study and evaluate the results of their SEO strategies. Many SEO companies have introduced domain authority scoring systems like Moz’s Domain Authority (DA) score, Ahref’s Domain Rating and Majestic’s Trust Flow and Citation Flow. These scoring systems were introduced to predict how likely a website is to rank on search engine result pages (SERPs).

Moz, an SEO companies behind matrics like Mozrank, Moztrust, Page  was the first to introduce Domain Authority (DA) Score. But what does this DA score metric really mean?


What is Domain Authority and why is it Important?

Domain Authority (DA) is a search engine ranking score developed by Moz, an SEO company behind many SEO tools. Domain Authority (DA) predicts how likely a domain is to appear in the SERPs compared to its competitors. The metric uses a algorithmic score ranges from one to 100 with higher scores corresponding to a greater ability to rank. For example, a website like has a DA score of 96, has a DA score of 94, CNN has 96.

Domain authority is a way of trying to predict how well a website will rank on search engines by following closely Google’s algorithm called PageRank. Google uses different metrics to rank different websites and one way webmasters try to make sure that their websites rank high is to align their SEO campaigns based off some of these metrics. Domain authority can be a very useful metric to know the rank status of a website in relation to your competitors, but you have to know that it is not a ranking factor for Google.

Websites like CNN, Amazon and Facebook have near perfect DAs over 95, as do leading online news networks like the Wall Street Journal and the NY Times. Small blogs with low traffic have single-digit range scores, while highly trafficked online businesses, depending on size, have mid-tier and high range close to 100.

Whereas Domain Authority, which measures the strength of the entire website, there is another metric by Moz called Page Authority which measures the predictive ranking strength of a particular web page, You can check the Page rank of any webpage with a Page Rank Checker Tool from SEOCentralTools.

How is Domain Authority Calculated?

Domain Authority is calculated based on Moz algorithm systems that uses over 40 different factors. Some of the major factors include quality of external backlinks, mozrank scores from total number of links, moztrust from strength of the links, quality content, social signals and search engine friendlinessetc. Moz issues a DA score from 1-100 with higher scores corresponding to greater likelihood of ranking.

The number of unique backlinks your website has earned from different root domains is one major factor. So if your website has 30 external links from one website, then you only have one linking root domains. If you have 30 backlinks from 10 different websites, then you have 10 linking root domains. Th links from different sites is of a higher value and will boost your ranking more than earning many backlinks from a single website.

Domain Authority takes into account not just the number of backlinks that are pointing back to your website, but also the quality of the backlinks. It measures how closely your website is connected to trusted domains. Trusted domains are .edu or .gov websites. A backlink from any high quality domain is considered a sign of trust that helps increase your MozTrust rating, which is also based on a 0-10 rating.

The social signals and and the quality of the content on the website is also considered. For instant, it’s safe to assume that a piece of content that is shared, liked, and commented on hundreds of times must be of high quality. Moz uses the same social signals factor in determining domain authority scores.

The higher the domain authority score, the better your chances of ranking in the SERPs. You can check the Moz Rank of any website with Moz Rank Checker Tool from SEOCentralTools


Relevance of Domain Authority to SEO

How Google determines the authority of a website has long been a matter of debates, hence the introduction of metric system like DA score. In the SEO world, website authority depends primarily on how much credibility your website has built up online over the years. According to SEO sources, About 22 percent of Google’s ranking algorithm depends on the number of links to a domain which is also called “link authority characteristics,” and the quality of these links. Also, about 20 percent depends on the number of links to a particular page which is know as "page-level link characteristics".

So the authority of your website in the eyes of Google based on your link progiles influences how well you can rank in search engine results. Google wants to provide its users with reliable information and results. This means that the more authority your website has, the more visitors you can attract through organic search.

If Google doesn’t consider your website important, you will rarely make it to the top of search engine results for any of your targeted keywords. Consequently, the authority of your website has a direct impact on your ability to reach users or visitors online. This means that improving your reputation and building trust with search engines should be important factors in your SEO strategy.

Essentially, the most important factor in your site’s authority is the quality and quantity of links it gets from other sites. Since Moz Domain Authority uses these same factors to determine its scores, its safe to assume that you have a chance of ranking well in Google if you have a very good DA score.

When your website’s backlink profile is full of links from higher DA websites, you’ll see a greater impact than if you just have backlinks from lower DA websites.
