Why Domain and Page Authority Are Important in SEO
Page and Domain Authority are machine learning ranking models that can be used by a search engine optimization company to predict the likelihood or the possibility of a single page or domain to rank in search results, regardless of page content. They can be both used to quickly target pages and websites that have the best potential to perform well in search engine results pages (SERPs).
What is Domain Authority and its importance in SEO?
Domain Authority predicts the performance of a website in SERPs rankings. It is a calculated metric that measures how well a given domain is likely to rank in Google.com’s search results.
Search Engine Optimization Experts could be used it to compare one site to another and track the “strength” of their website (entire domains or sub-domains) over time.
Domain Authority is based off of the Linkscape web index. Linkscape is a link building “supertool” and includes link counts, mozRank, mozTrust, and dozens more. It uses a machine learning model in order to predicatively find an algorithm that best correlates with rankings across thousands of search results that we predict against.

How is Domain Authority Scored, Calculated and Determined?
Domain Authority is scored based on a 100-point logarithmic scale – logarithmic scale that ranges from 0 to 100-points. So the higher the Domain Authority, the greater is the potential for an individual page on that domain to rank well. It is calculated by combining all other link metrics (linking root domains, number of total links, mozRank, mozTrust, etc.) into a one single score.
It is determined by employing a machine learning model against Google’s algorithm to best model how search engine results are generated. The calculation includes over 150 signals. The model used is constantly refined over time. This means that a website’s Domain Authority score will often fluctuate. For this reason, Domain Authority is best used as a competitive metric against other sites as opposed to a historic measure of your internal SEO efforts.
