What Is Website Authority?
Website authority (also called domain authority) is a measurement used to evaluate a domain’s overall quality and SEO performance.
For example, Semrush’s Authority Score is a compound metric that’s calculated based on the website’s referring domains, backlinks, organic traffic, and other factors.
This value is expressed on a scale from 0 to 100. The higher the number, the stronger and more authoritative the website is. And the likelier it is to rank well in Google’s search results.
How Does Semrush Calculate Domain Authority?
The Authority Score calculation is designed to mimic Google’s ranking systems. And it uses machine learning to measure every domain’s authority based on three main facets:
Backlink Signals
The quality and quantity of backlinks pointing to the website.
Organic Traffic
The estimated amount of organic traffic the website gets each month.
Spam Factors
An evaluation that detects manipulation or spam in the website’s link profile. This includes checking for the following spam indicators:
No organic rankings on the search engine results pages (SERPs)
An unnaturally high percentage of dofollow backlinks
An imbalance between links and organic traffic
Too many referring domains with the same IP address
Too many referring domains with the same IP network
The presence of another domain with an identical backlink profile
Why Is Authority Score Important
Compared to similar metrics, Authority Score is the least susceptible to manipulation when evaluating domains. This is because it considers signs of link spam in addition to the website’s backlink profile and organic traffic performance.
That said, Authority Score and similar metrics aren’t official Google ranking factors and don’t directly affect search results.
