Moz Metrics

Anyone who has ever had the slightest interest in SEO will have come across the giant known as Moz. Over the years it has developed from an early (and rudimentary) backlink analysis tool into one of the largest and most respected SEO communities on the internet. Their open site explorer tool is often the first glimpse SEO newbies have into the world of backlink analysis (because there is a free version). It's generally seen to be inferior to the powerhouses of Majestic and Ahrefs due to them having a much smaller link database.

However, what they lack in quantity they make up for in quality. Moz and their open site explorer provide real and useful information to new and experienced SEOs alike. To prove this fact when people talk about link profiles in any way, shape, or form, they often use the metrics from Moz. Examples of these situations are:

 • When you are buying or selling links
 • When you are buying new domains
 • When you are doing keyword research
 • When you are assessing competition

Moz's metrics are seen as one of the most reliable ways to get an at a glance overview of the quality of a site's or URL's backlink profile. The two main metrics you should concern yourself with from Moz are Domain Authority (DA) and Page Authority (PA). However, our tool allows you to check Linking Root Domains (LRD), Inbound Links (IBLs) and Spam Score. Scroll down the page further and we will go into more detail about what information Moz provides.

What Is Domain Authority?

Domain Authority (DA) is the way Moz describes the overall power of a domain. The higher the domain authority rating, the more powerful the domain is. Domain authority is generally seen as how 'trustworthy' the domain is overall. It's an easy way to tell if a domain you are inspecting has the power of Wikipedia or if it is a random blog with spammy backlink profile.

It is scored on a scale of 10 to 100 and it is a logarithmic metric. This means that it's much harder to increase your domains DA from 50 to 60 than it is from 30 to 40. It is calculated based on a websites overall backlink profile. Moz say they use machine learning to take into account many factors when calculating DA. They say that their algorithm actually adjusts the way they rank DA based on thousands of real world rankings they are tracking. They are basically trying to mimic the way Google views the power and the reputation of sites.

To increase your DA you need to try and get more links to your website from powerful pages. What this means in practice is 'get links from pages that have lots of good links themselves'. The links can go to any indexed page on your website and do not have to go to any specific page to increase your DA.

What Is Page Authority?

Page authority (PA) is a very similar concept to domain authority. The only real difference is that it focuses on individual pages instead of the overall domain. The way PA is calculated is very similar to DA. Moz states that they use the same machine learning algorithm to deduce how much PA should be given to a page and that they adjust their equations regularly. The main difference, of course, is that Moz is only taking into account links that are going to the page in question.

The DA of a site does provide a little boost to the PA rating of a page. Sites with a higher DA will have a better starting PA rating due to internal linking. However, the primary concern of PA is the amount (and quality) of external links going to a page. To increase your PA you need to do the same thing as you do to increase DA - build links. But (at the risk of stating the obvious) you need to build links to the specific page you want to increase the PA of.

So there you have it, a brief overview about two of the most powerful and useful metrics in the world of SEO.

To Recap:

 • Domain Authority refers to how powerful and trustworthy the domain is
 • Page Authority refers to how powerful an individual page is

If you are new to SEO (or even experienced), we highly recommend you get yourself familiar with Moz and their DA / PA metrics. It's a free and valuable resource that will dramatically improve the quality of your backlink analysis efforts almost instantly.
