Domain Authority (DA) is a metric created by Moz. DA is measured numerically – from 0 to 100. It is considered by many to be a solid way to determine the quality of a website and that it affects search engine rankings.

While there are some SEO experts who believe that Moz’s DA is flawed and cannot guarantee the quality of a website in Google’s view, with the “death” of Google’s PageRank, DA is perhaps the best metric we can rely on today.

There are other, however, ways to determine the quality of a website, like using other tools to check the quality and quantity of backlinks, and keyword rankings. You can then put together the results of your research to identify the quality of your own site.

Still, DA is a convenient and quick metric that provides an overall view. It does help you rank better, so it is worth your while to take actions to increase website domain authority.

Before you do that, you need to understand what is taken into consideration in calculating DA.

1. Domain age
2. Number of backlinks
3. Authority of linking domains (and then some)

How can you increase website domain authority?

1. On-site elements (speed, internal links, etc.)
2. Linkable (high-quality) content
3. Content marketing
4. Linkbuilding

These are some concrete steps that will help you increase your site’s DA.

For more details and more elements that will push your DA score up, take a look at the infographic below. Just remember, it is a good idea to not rely solely on DA.
