DA PA Checker - ATZ SEO Tools
The Site DA score [developed by moz.com] reflects a website's "strength" and relevance for a certain subject or industry. It's a logarithmic scale of zero to one hundred points that predicts how well a website will rank in search engine results pages (SERPs). The number of points received by a website determines its DA.
Page Authority (PA) is a single-webpage quality score that predicts how well a website will rank on a search engine results page (SERP). Moz is the one that developed the term "page authority." Page Authority is a scale of one to one hundred. The majority of SEO professionals believe that the PA score is quite significant, and they are correct.
