What is Page Authority?
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. Higher page authority means greater chances of your page showing up on search engines, and that your page will be placed closer to the top of the search results. Note that page authority is related to the pages within sites, not the site itself.
