Domain Authority (DA) and Page Authority (PA) are Moz‐developed SEO metrics that estimate how well a website or web page may rank in search results. DA scores a whole website on a 0–100 logarithmic scale – higher scores mean greater ability to rank. PA applies the same idea to individual pages. These scores are based on factors like link equity and content quality. While Google itself doesn’t use DA/PA as ranking signals, SEOs rely on them as useful benchmarks. In short, a higher DA or PA generally indicates stronger SEO authority for that domain or page.
DA and PA help SEO professionals prioritize link-building and outreach. A site with a high Domain Authority is viewed as more “trustworthy” by search engines, and earning backlinks from such sites can boost your own rankings. Likewise, high Page Authority signals that a specific page is powerful in search. In practice, you want backlinks from pages and domains that both have strong scores. As one SEO guide explains, “DA does correlate with rank” and you “want links from high authority… pages… to rank higher”. By checking both DA and PA, you can find the best link targets. (For example, a page on a site with high PA but low DA might be less valuable than a link from a high-DA site.) Evaluating these metrics helps you spot strong competitors and promising sites for guest posts or partnerships.
