Page Authority vs Domain Authority. The metrics DA and PA are essentially equivalent. On the other hand, the DA score predicts how well a domain will rank overall in the SERPs, and the PA score predicts how well a given webpage will rank in the SERPs. Website Authority (PA) is a score created and maintained by marketing analytics business Moz to predict where a certain website will rank on search engine results pages (SERPs). Page Authority is different from Domain Authority, which evaluates the authority of the entire website. Domain Authority (DA) is a Moz search engine ranking score that predicts how likely a website is to rank in search engine results pages (SERPs). Domain Authority scores range from one to 100, with higher scores indicating better chances of ranking. Domain Authority and its page-level counterparts Page Authority – DA and PA – are two of the most well-known and respected metrics in the SEO business, commonly used to assess the rankability of a domain or page.
