Page Authority (PA) refers to a metric developed by Moz, a company specializing in search engine optimization (SEO) tools. It predicts how well a specific webpage is likely to rank on search engine result pages (SERPs). PA scores range from 1 to 100, with higher scores indicating a greater likelihood of ranking well.
The score is based on various factors, including the number and quality of backlinks to the page, the page’s content, and other SEO-related elements. Page Authority is used by SEO professionals to gauge the strength of individual pages and to compare the ranking potential of different pages within a site or across different sites.
