Definition: Domain Authority (DA) is a search engine ranking score that predicts how likely a website is to rank on search engine result pages (SERPs). Developed by Moz, it ranges from 1 to 100, with higher scores indicating a greater ability to rank.
Components: DA is calculated by evaluating multiple factors, including linking root domains and the number of total links, into a single DA score. The score is used to compare websites or track the "ranking strength" of a website over time.
Usage: While Domain Authority is not a metric used by search engines to determine rankings, it provides a useful way for marketers and SEO professionals to gauge the effectiveness of their SEO strategies and the competitive edge of their websites in search results.
