t first glance, Domain Authority and Page Authority metrics may seem similar. However, there are several differences, albeit subtle, which set them apart. Let’s look at each below.
Purpose
Domain Authority helps you know the status of your web property compared to your competition and predicts the likelihood that your website will rank in the SERPs.
Page Authority, on the other hand, predicts how a particular page will rank on the SERPs. It helps you prioritize and define the actions you need to improve or develop based on the individual page with the most scope for improvement.
Data
Domain Authority data is drawn from Moz’s web index tool and considers several factors, including links and linking root domains.
Page Authority considers over 40 factors like link counts and others but doesn’t include keyword use or content optimization.
Calculation
When calculating Domain Authority, Moz uses an algorithm powered by machine learning that evaluates the linking root domains and number of links on your site to derive a score.
The score ranges from 1-100 and depending on the figure you get, you can track the ranking strength of your site over the competition.
Page Authority is also calculated using an algorithm, but it considers link counts and other factors to derive a score ranging from 1-100 on an individual page.
