Once I began to take blogging seriously I kept coming across the mysterious term 'DA'. It didn't stand for District Attorney, or Deviant Art, or even Domineering Aardvarks. What it actually stood for was 'Domain Authority'.
So what is Domain Authority?
Domain Authority predicts how well websites rank on search engines, and comes in the form of a score between 1 and 100. The higher the score, the better the website will rank. Examples of websites with a DA of 100 include Facebook, Twitter and Pinterest.
Page Authority or PA, on the other hand, scores a specific page on the website.
Does my blog have Domain Authority?
The basic answer is: yes. The full answer is slightly more complicated. For your blog to have its own Domain Authority, it has to have its own domain. My domain is babiafi.co.uk, for instance. If your blog address is a subdomain, like babiafi.blogspot.uk, its DA will be 'shared' with the host domain.
When I had that blogspot address my DA would come up as 95 - but that was actually Blogger's DA. I had no Domain Authority of my own. You can find out your DA HERE; you can also download the MOZ toolbar which lets you be nosy and check out the DA of every website you visit. DA is not static either, it is updated roughly every month, when the Mozscape link index is updated.
Why is Domain Authority important?
DA is only a prediction of how well a website ranks and, as the cynical may well point out, is the rather recent brainchild of Moz, a digital marketing company. But - your DA is used in lots of other settings too. It impacts on your Tots100 score, for example, and many brands won't work with a blog which has a DA of less than 25 or so.
How is Domain Authority calculated?
There are over 40 different factors used to calculate a website's DA, but some of the big ones include:
- Age of the domain.
- Domain popularity. I.e. the ratio of links from and to your website.
- Size of the website. The more content there is to be indexed, the better chance a site has of being ranked highly.
- Number and quality of backlinks.
- Moz metrics like MozRank and MozTrust.
