"Page Authority (PA) is a third-party metric created by Moz that estimates the relative ranking potential of a specific webpage on a 0-100 scale. A higher score suggests the page is more likely to rank competitively in search engine results pages (SERPs)."
"Moz calculates Page Authority using a machine learning model trained on thousands of search result data points. The primary input is the quality and quantity of inbound links pointing to a given page."
"One important clarification: PA measures a single page, not an entire website. If you want a domain-level signal, that is what Domain Authority (DA) is for."
"No. Page Authority is not a Google ranking factor. Google doesn't publish a Page Authority score, and it doesn't use Moz's PA metric in its algorithm."
Page Authority (PA) is a metric by Moz that estimates a webpage's ranking potential on a 0-100 scale. A higher PA indicates a better chance of ranking competitively in search results. The score is logarithmic, meaning improvements become harder at higher scores. PA is calculated using a machine learning model based on inbound link quality and quantity. It is important to note that PA measures individual pages, not entire websites, and is not a factor in Google's ranking algorithm.
