It is known as Domain Authority.

In this post, I would be discussing the 5 Best Free Domain Authority Checker Tools that will help you to know the domain authority of a website.

Domain Authority is quite a popular term these days.

However, if you still are not aware of this highly important term, here is the simple definition that explains what domain authority is.

What is Domain Authority?

Domain Authority is a Web Metric which has been developed by Moz. It’s a search engine ranking score that has been developed by Moz.

It is a score or grade (ranging from 1-100) that estimates or determines the possibility of a website for ranking on Google and other Search Engines.

What is Domain Authority

Higher the score, greater is the ability of a website to rank better on SERPs (Search Engine Result Pages).

With Domain Authority, you can come to know how well your website will rank on SERPs.

So, a website with high Domain Authority can rank well on Search Engines.

Domain Authority is used to compare one site to another. It can also be used to track the “strength” of your website over time.

In fact, multiple factors are evaluated for calculating the Domain Authority of a website.

Domain Authority is calculated by combining all other link metrics such as the number of total links, linking root domains, MozTrust, MozRank, etc. As much as 40 signals are used in this calculation. It is scored on a 100 point, logarithmic scale.

The domain authority score can be used for comparing websites. It can track the “ranking strength” of a website over time.

So, it means that your website’s Domain Authority score is not fixed. Rather it will often fluctuate.

So, it is advised that you should use Domain Authority as a competitive metric against other websites rather than using Domain Authority as a historic measure of your internal SEO efforts.

Domain Authority helps to answer the question, “How strong are the page’s links to rank for queries in Google?”

Having said this, it is difficult to influence the Domain Authority directly. So, it is difficult to grow your Domain Authority score from 70 to 80. However, by improving your overall SEO, it is possible to influence this metric.

Particularly, you should focus on the link profile of your website and make efforts on getting links from other well-linked and high ranked pages.

There are several tools for viewing the Domain Authority of a website. For instance, you can use MozBar (a free Chrome Extension). It can be measured using the backlink analysis tool, Link Explorer. In fact, there are dozens of SEO Tools across the web to measure Domain Authority.

Here, we have listed 5 Best Free Domain Authority Checker Tools to help you figure out the domain authority of your website.

The Technical Definition of Domain Authority

Domain Authority is based on the data from the Link Explorer web index. It uses dozens of factors in its calculations.

For example, Domain Authority calculation employs a machine learning model based on the “best fit” algorithm that correlates the link data with thousands of actual search results. They are used as standards to scale against.

What is meant by Good Domain Authority?

Sites with very large numbers of high-quality external links (such as Wikipedia or Google) stand at the top in the Domain Authority scale.

However, websites with fewer inbound links have a much lower Domain Authority (DA) score.

The brand-new websites have a Domain Authority score of one.

In fact, the Domain Authority of a website is indicative of its ranking ability.

That said, it should be kept in mind that getting a very high DA score shouldn’t be your only goal.

It means that you should look at the DA scores of the sites that you directly compete within the SERPs and go for having a higher DA score than your competitors.

So, Domain Authority should be viewed as a comparative metric and not as an absolute concrete score.

It is used to know which sites have more powerful link profile than others. Essentially there is not a “good” or “bad” Domain Authority score.

What is Page Authority?

Page Authority is a score that is also developed by Moz.

It predicts how well a specific page will get ranked on SERPs (Search Engine Result Pages). It is measured by a score ranging from one to 100.

Page Authority

So, a high Page Authority means a greater ability to rank. Page Authority is based on data compiled from web index. It takes into account dozens of factors.

For example, Page Authority uses a machine learning model for identifying the algorithm correlating with rankings across the thousands of SERPs to produce score using that specific calculation.

Page Authority scores on the 100-point logarithmic scale.

It means that it is easier to grow your score from 20 to 30 than to grow it from 70 to 80.

Moreover, the Page Authority algorithms are frequently updated, so you can find your PA score to fluctuate from time to time.

However, like Domain Authority, Page Authority is also best used as a comparative metric. It should not be taken as an absolute, concrete score. Rather it is used to determine which pages have more powerful link profiles than others.

So, Page Authority is a comparative tool.

What is Moz Rank?

Moz Rank is representative of a web link popularity score. It shows the importance of any given web page or website on the internet.

So, Moz Rank shows the popularity score for any website. It is measured on a scale of 0 to 10.

The websites which have zero (0) Moz Rank is least popular whereas websites with 10 Moz Rank is the most popular.

It’s calculated keeping into account backlinks to the page as well as linking websites quality.

So, good websites having many backlinks tend to get a high value of Moz Rank. The higher is the quality of incoming links; the higher is the Moz Rank.

It determines the popularity of a given page on the internet. It reflects the importance of a web page on the Internet viz a viz others.

High-quality links get to boost the Moz Rank of a web page.
