The world of Search Engine Optimisation (SEO) seems to get a little more complicated with every passing year. As search giants like Google introduce smarter ranking algorithms, digital marketers are frantically trying to keep up with the latest best practices. For example, the lack of an SSL certificate on your website could see your website slide down Google’s rankings.
However, your goal will never change. When someone is searching for something that you offer, you want your pages to be listed as high as possible on the Search Engine Results Page (SERP). SEO experts are always on the lookout for the latest metrics to discover what is determining their pages’ rankings and how to improve their SERP placement.
DEFINING DOMAIN AUTHORITY
One relatively new metric is called Domain Authority (DA). This ranking score was developed by Moz, a Software as a Service (SaaS) company that offers tools for digital marketing. Domain Authority is a ranking score that aims to predict how well a website will rank in search engine results. DA is scored on a scale from 1 to 100, and the higher, the better. This score is not used or even considered by search engines like Google. Instead, it attempts to predict how Google and others will rank the site.
Figuring Domain Authority involves over 40 factors but is primarily based on the number and quality of inbound links. This means to calculate the score, Moz looks at the total number of linking root domains and the number of total links. In other words, how many unique websites link to your website? And, what is the total number of links to your site from all their pages? Finally, it uses the quality of those pages to determine a value for each link.
The general idea is that search engines determine how valuable a web page is based on how many other websites link to it and the quality and relevance of those sites. The more high-quality sites linking to yours, the higher your Domain Authority and the higher your chances are for ranking high in the SERP.
WHAT IS A GOOD DOMAIN AUTHORITY?
Since 100 is the best DA score a website can receive, it may be tempting to make 100 your goal. However, that is not necessarily the best target. DA is meant to b comparative. You don’t need a top score. You simply need a rating higher than other sites you are competing with for a spot on the results page.
Don’t get disheartened by comparing your online presence with Google, Amazon, and the BBC. But it is useful to identify your competitors and compare your progress alongside them. The bottom line is if your Domain Authority is higher than your competitors, then your site will probably appear higher on search engine results pages.
