What is domain authority?

Domain authority is the measurement of the power of a site in the search engine world. The higher the Domain Authority the higher you can rank for your content. Keep in mind other factors as well are taken into account but with a very low domain authority you will likely not rank well against your competitors.

Domain authority is based on the following factors:
  1. Age of domain name
  2. Popularity of your site
  3. Size of your website
How do I check the domain authority of my website?

Moz has a good free Domain Authority checker which you can use to get an idea of the DA of your domain.  Moz can be credited with the DA algorithm. DA is a great metric to view against your competitors. A brand new website would have a very low or 0 as the DA number.

Here is an example of Twitter which has really high domain authority. Notice the number closest to 100 is the idea which will give you great power in the eyes of the search engines.

You can use this DA number against your competitors domains to see how they look against your own website. If they have a higher DA it’s probably likely that there content will rank much higher than yours. Keep that in mind when your comparing authority rankings against your competitors.

How do I increase my Domain Authority?

It is difficult to directly increase your domain authority but establishing back links is a great way to start. I would focus on high quality backlinks in order to increase the DA otherwise lower quality backlinks will likely just be a waste of time. Learn more about backlinks here. Over time your DA will increase and your content should start ranking better.

What if I paid another site to link to me?

It’s possible to also get paid links but Google is really against doing such kind of behavior and we do not recommend you try this. It would be better if you can get another site to link to your site then you can link back to there site as well.

Technical details of domain authority:

Domain Authority is Moz’s calculated metric for how well a given domain is likely to rank in Google’s search results. It uses a machine learning model to predictively find an algorithm of search engine rankings across thousands of search results. It is based on data from the Mozscape web index and includes link counts, MozRank and MozTrust scores, and dozens of other factors.

It’s best to use Page Authority (PA) and Domain Authority (DA) as comparative metrics when doing research in the search results and determining which sites/pages may have more powerful/important link profiles than others. Specific metrics like MozRank can answer questions of raw link popularity and link counts can show the raw quantities of pages/sites linking—the authority numbers are high-level metrics that attempt to answer the question, “How strong are these page links in helping them rank for queries in Google.com?”
