What is Page Authority?
Page Authority is a score out of 100 that predicts the ranking ability of a single page in search engine result pages (SERPs). Oftentimes, it is used to measure the ranking strength of a page.
The metric is developed by Moz, it considers the backlink profile of a page and how often it is ranking in the SERPs. A page with higher Page Authority will have a greater ability to rank in the SERPs.
What is a good Page Authority?
It is best used as a comparative than a relative metric, so there is no absolute "good" or "bad" score. If the Page Authority of a page is higher than / or similar to other comparable pages, then its Page Authority is good.
