Domain Authority Background
Google founder Larry Page developed an algorithm called PageRank.
PageRank is a measurement of the number of links to a website but also their perceived quality.
This gave an ‘authority’ measurement for a website and allowed for a method to determine and sort which websites were of a higher quality than others and should therefore rank higher in the Google search results.
The logic being that a website with a higher number and quality of incoming links will have a higher PageRank and ultimately will perform better in the search engine results pages (SERPS).
PageRank was for a long time a useful quality measurement of a website and the PR Score of a website was often touted as an indicator of its value.
It has now decreased in use as Google no longer publishes regular updates to PR Score and arguably it is used only as an internal metric for the company.
Domain Authority is a metric that was created by Moz and in many ways works the same way a PageRank did. The higher the score the better.
It is important to note that it is not used by Google. It does not have a direct effect on SERPS but it is a good indicator of a websites ability or likelihood to rank.
It looks at a variety of factors to establish the quality of a domain including:-
- Quality and number of links
- Quality and number of outgoing links
- The age of the Domain Name
- Range of Links and Diversity
- Range of Links over time
Current usage of Domain Authority
Arguably Domain Authority is a more useful metric to use then PageRank asm being more readily available it allows comparisons between websites.
This is for a number of reasons with the key one being that Domain Authority is kept up to date whilst PageRank has fallen in usage.
Many SEO tools and websites use Domain Authority and it is now a well established metric for those involved in Digital Marketing.
Checking Domain Authority of competitor websites gives a good indicator of how well a website is likely to rank in relation to its competitors.
What is a good Domain Authority score?
It is interesting to note that they do not score a perfect 100.
This is because the score is a comparison figure and gives a good indicator of how your website is likely to perform in search results compared to your competitors.
Comparing Domain Authority Scores
If your competitors are all scoring in the 40s and your website scores 60, then your score is very good and you should outrank them. Similarly, if your score is in the 30s and your competitors all score 60+ then you have work to do to improve your SEO ranking.
How to improve your Domain Authority
There is a lot that can be done to improve Domain Authority.
You should remember that it is easier to improve a score from 30 to 40 than it is to improve a score from 70 to 80.
It is also very difficult to obtain a score of 90+ as these businesses tend to be huge multinationals or organisations (e.g. Wikipedia) which have thousands if not millions of backlinks.
