How Does Moz Calculate Page Authority?
Moz uses a similar scale as domain authority to score page authority, meaning a 100-point, logarithmic scale. Keep in mind that even if you haven’t done anything to a page, its score may still fluctuate due to the fact that Moz is constantly updating their algorithm.
The following are some of the ranking factors that Moz uses to determine page authority:
- Social signals such as the number Facebook Likes, Twitter Retweets or LinkedIn Shares a page has received.
- The number of root domains linking to the page.
- The number of root domains linking to the page using partial match anchor text.
- The number of subdomains that link to the page.
- The number of quality websites linking to the page.
- The number of external links a page has.
