Domain Authority Defined
There are a variety of approaches to grading the quality of a website. One of the more black and white tactics is Domain Authority (DA). Once you know the DA of your site, you can use it in several ways, including to increase the quality of your SEO.
Domain Authority was developed by Moz and is described below:
Domain Authority is a score (on a 100-point-scale) developed by Moz that predicts how well a website will rank on search engines. Use Domain Authority when comparing one site to another or tracking the "strength" of your website over time. We calculate this metric by combining all of our other link metrics –linking root domains, number of total links, MozRank, MozTrust, etc. –into a single score.
Domain Authority scores are from 1 to 100 and is an indicator of how high on a search engine results page (SERP) a given site will show. Higher numbers mean that a site will show up higher on a SERP. It is also a sign of the credibility of your business. One way to increase your DA is to have many quality links to your site and from your site to other sites.

How Does Moz Compute DA?
Domain authority is computed using a logarithm that increases exponentially on a scale from 0 to 100. What does that mean? It means a few small changes might increase your DA from 10 to 20. But it will be considerably harder to move the marker from 90 to 95.
One of the main factors that goes into the Domain Authority is links. Links from a given website give it authority. It’s like getting points, and the total number of points, gives the final score, your Domain Authority. But not all links are worth the same number of points. Some are worth more points than others. High DA sites are worth more points than lower DA sites.
What is Considered a High Domain Authority Score?
Businesses that have a large following and are often seen as experts in their field are linked to often and therefore have higher Domain Authority scores. For example, websites like WebMD and Apple have high Domain Authorities, with scores over 90.
Smaller, start ups will have lower Domain Authorities, sometimes ranging between 20 and 30.
All sites will start at 1, until they can build up a following to start having other sites link to their site.
Why Worry About DA?
Domain authority is important when trying to get your site to rank against your competitors. The key phrase here is “against your competitors.” This means that if your competitors all have scores in the 20s, then you don’t need to shoot for a score in the 80s, but rather just one higher than your competitors.
You can always pay to be at the top, using PPC, but in the long run, you will want to organically get your site to rank higher. To do this you can use the DA to analyze the backlinks of your competitors and aim to make yours better. You should be trying to attract higher quality sites to link to yours.
