Hi Friends,
PA(page authority) & DA(Domain authority). PA describe the probability that a specific page from the site will be found on the search engine. Higher PA means there are great chances of the page showing up on the search engines.

DA is very important for a website because it will help new pages of content in getting indexed more quickly and have a better chance of ranking prominently in the search results. Domain Authority measures the predictive ranking strength of entire domains or subdomains whereas Page Authority measures the strength of individual page.
