Page Authority scores range from one to 100, with higher scores corresponding to a greater ability to rank.

Page authority is an SEO term used to describe the probability that a specific page from your site will be found on a search engine. Page authority is based on a logarithmic scale from 0 to 100 and deals with the relevance of information and links within site pages to one another.

Page Authority (PA) is a metric developed by Moz that predicts how well a specific webpage will rank in search engine results pages (SERPs).
