Domain Authority & SEO: Everything You Need To Know


If you have been poking into the SEO sphere, you may have unsuspectedly come across a thing we call Domain Authority, DA for short. 

In Australia, many businesses across all industries compete to rank higher for competitive search terms. If you find that your top ranking SEO keywords are dropping and are curious about how Domain Authority impacts your digital presence, we got you covered.

What is Domain Authority?

In a nutshell, Domain Authority is a well-known SEO metric that indicates a website or a domain’s overall strength, aka ‘Authority Score’.

Domain Authority runs from the scale of 1-100, with a higher score indicating that your website will have a better chance of ranking competitively in search engines.

Moz developed this particular SEO scoring system to approximate how well a website performs or ranks in Google SERPs. This came as a result of Google officially removing their famous PageRank scoring system from public view.

Over the years many leading SEO tools have also come out with their own variations. See below for the most popular ones.

Why is Domain Authority Important?

Calculating your website’s Domain Authority will help you assess your position and strength in the market.

To check your site’s Domain Authority, the scoring platform will compare your data along with millions of others through many significant ranking factors. Moreover, calculating Domain Authority involves complex machine learning that uses a bespoke set of algorithms to properly benchmark your site ranking across thousands of others.

How is Domain Authority Calculated?

DA calculation involves assessing several ranking factors into one score, including internal/external links and linking root domains. But keep in mind that Domain Authority isn’t one of Google’s official ranking factors and doesn’t affect how you rank on Google SERPs.

These scores will only reflect how well your website performs compared to your search competitors. That said, our SEO specialists use them, among other reliable metrics, to measure your ranking strength and gain data-driven insights over time.

The scoring system also uses a machine-learning algorithm to predict your domain’s popularity on Google’s search results. In other words, if your website appears more on several Google SERPs than a different site, then expect your overall DA score to be higher than the competitor.

Additionally, your Domain Authority score will fluctuate in real-time since it results from machine learning having to process new, incoming links in real-time. That means as new data and metrics get incorporated, the more likely your score will change.

Say a competitor site named Brand B acquired one million new links. In that case, Brand B will climb up the charts as they score a higher DA than others. As a result, your score and others below Brand B will slightly decrease, relative to how much it increased.

The sheer competition on the upper hand is the reason why growing your Domain Authority from 10 to 30 is more manageable than ranking from 80 to 90.

DA scores are highly subjective and do not affect your Google SERPs. That’s why our SEO specialists at Red Search use them for comparative analysis instead of an absolute metric.

How to Check Domain Authority Score?

If you want to assess your site’s Domain Authority, you can check out the free Link Explorer tool from Moz.

But if you only have so much time and knowledge to properly assess your brand, our SEO specialists at Red Search will gladly help you out. We can make an accurate evaluation of your SEO health and give you insights that you and your team will understand.

How Do I Increase Domain Authority?

One way to improve your DA ranking is to ramp up your link building efforts. That’s because Domain Authority primarily measures the quality and quantity of new backlinks.

However, the sheer amount of big data in measuring DA makes it virtually impossible to directly influence your ability to rank in Google’s search results. Domain authority only predicts how well your site will rank.

Since Google incorporates countless ranking factors to evaluate a website, the Domain Authority calculator can only approximate those results.

It’s important to note that diversification is key with any type of link building. To ensure your DA is constantly improving and stable, all various types of backlinks should be built, acquired or earned. Putting all your eggs in one basket, in one acquiring one type of link is a dangerous practice.

How are Domain Authority and Page Authority Different?

You might hear the word Page Authority along with Domain Authority and end up switching the two terms. 

However, Page Authority measures the ranking strength of a single webpage. At the same time, Domain Authority evaluates the domain as a whole, including all its subpages.

Hence, if you only want to see how well your latest blog post ranks on your desired keywords, running it in a Page Authority check will be the best way to assess it.

On the other hand, you should do a Domain Authority check if you want to evaluate your entire website’s ranking strength. DA results may involve more metrics and figures than PA, so you need an SEO specialist to sort out the vital insights to make data-driven decisions.

Final Thoughts

With more Australian businesses competing to rank on Google’s first pages, you should leverage every tool in your search arsenal.

That includes comparative metrics such as Domain Authority, along with confirmed search ranking factors, such as page loading speed and on-page optimisation factors. 

Domain Authority scores fluctuate over time, so you need to stay ahead of changes and potential opportunities to constantly improve your score.
