Page Authority (PA)

What is a Page authority?

Page Authority is a score that determines how high will the web page appear on search engine result page (SERP). This metrics is provided by Moz.

Page Authority is based on various other statistics, such as Mozscape web index, link counts, MozRank and MozTrust.

The ranking is a number between values of 0 to 100. It is a comparative score, so you can not surely tell whether the page's ranking is good or bad. But overall higher Page Authority means that it should score better in the search results.
